1 00:00:01,120 --> 00:00:03,960 Speaker 1: Ron Anian. You know it's funny. Metal does this funny 2 00:00:04,040 --> 00:00:06,440 Speaker 1: thing where it starts to grab and snag and you 3 00:00:06,519 --> 00:00:08,440 Speaker 1: can't turn it the other way. You can't turn it 4 00:00:08,560 --> 00:00:10,600 Speaker 1: this way and all of a sudden snap and your 5 00:00:10,720 --> 00:00:16,960 Speaker 1: dogs Bob girl. I had at the car doctor, I 6 00:00:17,000 --> 00:00:19,439 Speaker 1: would change the oil every five thousand miles good synthetic 7 00:00:19,480 --> 00:00:22,080 Speaker 1: oils today or five to seven thousand miles. But then 8 00:00:22,120 --> 00:00:25,400 Speaker 1: there's also whose oil filter is Welcome to the radio 9 00:00:25,520 --> 00:00:29,800 Speaker 1: home of ron and Anian the Car Doctor, since this 10 00:00:30,000 --> 00:00:33,120 Speaker 1: is where car owners the world overturned to for their 11 00:00:33,200 --> 00:00:37,320 Speaker 1: definitive opinion on automotive repair. If your mechanics giving you 12 00:00:37,400 --> 00:00:40,160 Speaker 1: a busy signal, pick up the phone and call in 13 00:00:40,560 --> 00:00:43,159 Speaker 1: the garage doors are open, but I am here to 14 00:00:43,159 --> 00:00:46,600 Speaker 1: take your call at eight five five five six and 15 00:00:46,680 --> 00:00:53,840 Speaker 1: now running. So I've got this way that you can 16 00:00:54,120 --> 00:00:56,760 Speaker 1: well all save money. Everybody's in for saving money, right, 17 00:00:56,800 --> 00:00:59,160 Speaker 1: and something that you can take into your own and 18 00:00:59,160 --> 00:01:01,520 Speaker 1: it gives you the power and the ability to do this. 19 00:01:02,840 --> 00:01:07,000 Speaker 1: I want you to think differently about repairs going forward. 20 00:01:07,640 --> 00:01:10,920 Speaker 1: And you know you can't do this. Gee. I took 21 00:01:10,959 --> 00:01:14,040 Speaker 1: it into a shop and it it did this noise 22 00:01:14,120 --> 00:01:16,360 Speaker 1: After the repair and I'm gonna take it back. And 23 00:01:16,400 --> 00:01:20,840 Speaker 1: it's eight months later because everything is changing. Here's the 24 00:01:20,840 --> 00:01:23,640 Speaker 1: classic reason why I went back to the gym this week. 25 00:01:23,680 --> 00:01:25,520 Speaker 1: I was started up again with cross fit so I 26 00:01:25,520 --> 00:01:28,399 Speaker 1: can be schelt come summer, which I've got a lot 27 00:01:28,440 --> 00:01:32,480 Speaker 1: to do between now and summer. Tom stopped and stop what. 28 00:01:32,560 --> 00:01:34,720 Speaker 1: I'm just gonna agree with you. Yeah, I just you know, 29 00:01:34,880 --> 00:01:37,600 Speaker 1: I just know what you're gonna say. And I was 30 00:01:37,640 --> 00:01:39,840 Speaker 1: talking to coach Brian and Coach Briant was telling me 31 00:01:39,880 --> 00:01:45,039 Speaker 1: about his wife's nineteen Honda Odyssey that the backup camera 32 00:01:45,160 --> 00:01:48,640 Speaker 1: wasn't working on and he said, you know, he goes, 33 00:01:48,880 --> 00:01:51,480 Speaker 1: there was an accident back in the fall and it 34 00:01:51,600 --> 00:01:54,680 Speaker 1: came out and it worked, but it didn't work, and 35 00:01:54,680 --> 00:01:56,960 Speaker 1: then it was staticky, and then it went dark, and 36 00:01:56,960 --> 00:01:59,320 Speaker 1: then it would come back, and then it stopped working altogether, 37 00:01:59,360 --> 00:02:02,960 Speaker 1: and now it just doesn't work. I said, okay, I said, 38 00:02:03,560 --> 00:02:05,800 Speaker 1: you know, because it was his somebody had backed into 39 00:02:05,880 --> 00:02:08,359 Speaker 1: or somebody hit the vehicle from behind, and they did 40 00:02:08,400 --> 00:02:10,120 Speaker 1: body work, they did hatchwork to it, you know, the 41 00:02:10,160 --> 00:02:14,200 Speaker 1: lift gate, and long story short, it came out and 42 00:02:14,240 --> 00:02:16,839 Speaker 1: he said it just wasn't right. And I said, well, 43 00:02:16,919 --> 00:02:19,960 Speaker 1: did they Did they do an a DOS calibration? I Well, 44 00:02:20,000 --> 00:02:22,040 Speaker 1: first I asked him, I said, does your vehicle, if 45 00:02:22,040 --> 00:02:23,680 Speaker 1: you look at your vehicle from the front, doesn't have 46 00:02:23,720 --> 00:02:26,320 Speaker 1: a camera under the rear view mirror looking forward through 47 00:02:26,360 --> 00:02:28,560 Speaker 1: the windshield And he said yes. I said, then your 48 00:02:28,639 --> 00:02:34,200 Speaker 1: vehicle has a DOS Advanced Driver Assist and he said, jeez, 49 00:02:34,240 --> 00:02:36,240 Speaker 1: what's that. I ran through the whole thing with him 50 00:02:36,240 --> 00:02:38,040 Speaker 1: and I explained it to him and he said, you know, 51 00:02:38,080 --> 00:02:41,959 Speaker 1: that makes sense, he goes, because also the blind spot 52 00:02:42,000 --> 00:02:46,280 Speaker 1: mirrors on the side don't work. And I asked him, 53 00:02:46,320 --> 00:02:49,239 Speaker 1: I said, did they do a calibration? If you look 54 00:02:49,240 --> 00:02:51,280 Speaker 1: at your invoice from the body shop, you know they 55 00:02:51,320 --> 00:02:54,120 Speaker 1: should give you some documentation. Does it say anything on 56 00:02:54,120 --> 00:02:57,320 Speaker 1: there about doing an ADS calibration? And he said, no, no, 57 00:02:57,639 --> 00:02:59,440 Speaker 1: not that I saw. He goes. It was just straight 58 00:02:59,440 --> 00:03:03,080 Speaker 1: you know, replay body work, you know, vendors, parts, paint, labor, 59 00:03:04,120 --> 00:03:07,960 Speaker 1: We're done. Well, that's the problem. So now he's got 60 00:03:07,960 --> 00:03:10,639 Speaker 1: to go back seven months later and play the ever 61 00:03:10,720 --> 00:03:13,120 Speaker 1: since game, which is tough, right, It's it's it's a 62 00:03:13,120 --> 00:03:15,400 Speaker 1: tough road to hoe and I feel for him, and I, 63 00:03:15,919 --> 00:03:17,760 Speaker 1: you know what, that's part of what I'm here for 64 00:03:18,040 --> 00:03:22,240 Speaker 1: is to explain this to you. It's it's not your imagination. 65 00:03:22,560 --> 00:03:25,799 Speaker 1: It is a different repair process. We're gonna fix cars 66 00:03:25,960 --> 00:03:30,440 Speaker 1: differently going forward. We have to. There's no choice. It's 67 00:03:30,480 --> 00:03:35,440 Speaker 1: the technology that's driving us here. So don't wait till 68 00:03:35,440 --> 00:03:37,960 Speaker 1: the last minute. If it's coming out of a body 69 00:03:37,960 --> 00:03:40,120 Speaker 1: shop after an accident, if it's coming out of a 70 00:03:40,120 --> 00:03:43,400 Speaker 1: mechanical shop and they've repaired something and that's something still 71 00:03:43,480 --> 00:03:46,680 Speaker 1: doesn't work, don't assume it's going to get better on 72 00:03:46,800 --> 00:03:50,120 Speaker 1: its own. And it's just you've got to get into it. 73 00:03:50,160 --> 00:03:52,120 Speaker 1: You've just got to get into it right away. I'm 74 00:03:52,120 --> 00:03:53,760 Speaker 1: gonna leave it there. We've got a lot going on 75 00:03:53,840 --> 00:03:56,400 Speaker 1: this hour. Uh you know, I want to get some 76 00:03:56,440 --> 00:03:58,920 Speaker 1: calls in. We've got Chuck kin Kaid from Mala coming 77 00:03:58,960 --> 00:04:00,800 Speaker 1: down around the on him of the hour to talk 78 00:04:00,800 --> 00:04:03,320 Speaker 1: to us about air conditioning. Next hour, we're gonna have 79 00:04:03,400 --> 00:04:06,520 Speaker 1: some memories of Uncle Steve as we celebrate him, and 80 00:04:06,920 --> 00:04:09,760 Speaker 1: memories of Memorial Day with Uncle Steve as we uh 81 00:04:10,200 --> 00:04:12,560 Speaker 1: observe Memorial Day weekend here on the Car Doctor. So 82 00:04:12,600 --> 00:04:14,200 Speaker 1: a lot to do, a lot to talk about. Let's 83 00:04:14,200 --> 00:04:17,160 Speaker 1: get the garage doors open, Let's go to Jeremy and Washington, 84 00:04:17,240 --> 00:04:19,560 Speaker 1: d C. Jeremy, Welcome aboard, sir, welcome back. How can 85 00:04:19,560 --> 00:04:23,960 Speaker 1: I help? What the perfect segue that you just had 86 00:04:24,000 --> 00:04:27,000 Speaker 1: For what I'm gonna ask you, I had a new 87 00:04:27,040 --> 00:04:29,279 Speaker 1: gears put in the front and rear of my silver 88 00:04:29,360 --> 00:04:31,520 Speaker 1: Rod and the differential to give me a little bit 89 00:04:31,600 --> 00:04:34,880 Speaker 1: of extra towing. I went from I guess GM had 90 00:04:34,880 --> 00:04:37,600 Speaker 1: went three forty two in it sounds right, and I 91 00:04:37,640 --> 00:04:40,280 Speaker 1: went up to yeah, and I went up to four elevens. 92 00:04:41,200 --> 00:04:44,800 Speaker 1: And since I had that done recently, when it is 93 00:04:45,680 --> 00:04:50,880 Speaker 1: about forty five and I come off the throttle, you know, um, 94 00:04:50,920 --> 00:04:53,640 Speaker 1: when it's unloaded, I tend to get a little bit 95 00:04:53,640 --> 00:04:57,000 Speaker 1: of wine um in that forty five mile prior. And 96 00:04:57,000 --> 00:04:58,839 Speaker 1: I'm just wondering if it's something I need to worry 97 00:04:58,839 --> 00:05:01,400 Speaker 1: about or I should just you know, because I mean 98 00:05:01,400 --> 00:05:03,520 Speaker 1: I've had some trucks that have a little bit of 99 00:05:03,560 --> 00:05:06,440 Speaker 1: wine in the back before, and you know, I'm wonder 100 00:05:06,480 --> 00:05:08,640 Speaker 1: if it's a if it's a bearing, I need to 101 00:05:08,640 --> 00:05:11,080 Speaker 1: worry about her. If it's just like you know, I 102 00:05:11,120 --> 00:05:14,120 Speaker 1: could imagine that new gears being put in in a 103 00:05:14,200 --> 00:05:18,840 Speaker 1: shop are never gonna be as perfect, perfect perfect as 104 00:05:19,560 --> 00:05:27,000 Speaker 1: you know factory gears, they were preinstalled. They should be, 105 00:05:28,080 --> 00:05:30,120 Speaker 1: they should be. Let me let me ask you this 106 00:05:30,480 --> 00:05:35,640 Speaker 1: is it the same brand of gear front and back? Yeah? Okay, 107 00:05:35,760 --> 00:05:39,960 Speaker 1: does does the front rear make any noise? Well? I don't, 108 00:05:40,080 --> 00:05:42,120 Speaker 1: you know. I rarely ever put it in four wheel drive, 109 00:05:42,160 --> 00:05:44,760 Speaker 1: you know what I mean? Almost never. I don't know 110 00:05:44,800 --> 00:05:48,200 Speaker 1: if it does or not. You should just it would 111 00:05:48,200 --> 00:05:51,720 Speaker 1: aid in the diagnosis. What I'm curious is, and I'm 112 00:05:51,760 --> 00:05:55,040 Speaker 1: not bashing the brand, but just depending upon what brand 113 00:05:55,080 --> 00:05:58,840 Speaker 1: of gear could it be cut differ Yukons what they 114 00:05:58,839 --> 00:06:01,719 Speaker 1: put in there. So then I would talk to the 115 00:06:01,800 --> 00:06:04,360 Speaker 1: Yukon guys and I would tell you, yeah, I mean 116 00:06:04,360 --> 00:06:05,960 Speaker 1: they've got a good reputation. I would talk to the 117 00:06:06,000 --> 00:06:08,200 Speaker 1: Yukon guys and say, hey, are your gears? Do your 118 00:06:08,200 --> 00:06:11,960 Speaker 1: gears tend to be a little louder overstocked depending upon 119 00:06:12,040 --> 00:06:15,559 Speaker 1: how they're cut, because some gear manufacturers, you know, cut 120 00:06:15,600 --> 00:06:18,440 Speaker 1: their gears at at a different angle and for you know, 121 00:06:18,480 --> 00:06:21,719 Speaker 1: more aggressiveness, better wear, better strength, you know, a hundred 122 00:06:21,760 --> 00:06:24,919 Speaker 1: different reasons. And maybe what you're hearing is just the 123 00:06:25,000 --> 00:06:28,520 Speaker 1: byproduct of the gear. You didn't change tires in doing 124 00:06:28,520 --> 00:06:30,720 Speaker 1: the dips, right, You just did the gears. No, I 125 00:06:31,080 --> 00:06:35,320 Speaker 1: did not, so you know, just thinking as a tire noise. 126 00:06:36,000 --> 00:06:38,440 Speaker 1: But I would clearly go back to the shop and 127 00:06:38,480 --> 00:06:41,360 Speaker 1: talk to them because is it the beginning of is 128 00:06:41,400 --> 00:06:45,400 Speaker 1: it possible that the opinion isn't torked properly? Is the 129 00:06:45,560 --> 00:06:49,120 Speaker 1: depth not set correctly? You know? How did they do 130 00:06:49,200 --> 00:06:53,280 Speaker 1: it regarding the opinion? Okay, question for you just right quick. 131 00:06:55,160 --> 00:06:58,520 Speaker 1: I'm a complete novice when it comes to axles. Is 132 00:06:59,480 --> 00:07:02,839 Speaker 1: where it is that the opinion that's the that's the 133 00:07:02,880 --> 00:07:06,000 Speaker 1: one that comes off the drive that turns right the opinion. 134 00:07:06,320 --> 00:07:10,520 Speaker 1: The opinion gear is the smaller round gear in line 135 00:07:10,560 --> 00:07:13,840 Speaker 1: with the drive shaft that's supported by the two bearings. Now, 136 00:07:14,400 --> 00:07:17,880 Speaker 1: depth of opinion, how it sits in the case on 137 00:07:17,960 --> 00:07:21,240 Speaker 1: a GM product like yours, is determined by the shims 138 00:07:21,440 --> 00:07:27,600 Speaker 1: or shim that's located between the bigger bearing closest to 139 00:07:27,880 --> 00:07:31,560 Speaker 1: the head that find that that connects to the gear. 140 00:07:31,960 --> 00:07:35,000 Speaker 1: That's depth as it sits down into the case. And 141 00:07:35,040 --> 00:07:39,040 Speaker 1: then backlash and preload is determined by the shims on 142 00:07:39,080 --> 00:07:45,640 Speaker 1: the sides oh next to the axel bearings. So bearing 143 00:07:45,840 --> 00:07:49,480 Speaker 1: bearing depth is probably pinion bearing preload and depth is 144 00:07:49,520 --> 00:07:52,920 Speaker 1: probably the most critical adjustment. They're all critical, but pinion 145 00:07:52,960 --> 00:07:54,800 Speaker 1: will be the one that's causing this noise if it's 146 00:07:54,840 --> 00:07:59,000 Speaker 1: not correct. If I'm going in there this weekend before 147 00:07:59,000 --> 00:08:01,600 Speaker 1: I go out, see, I'm gonna take it on a 148 00:08:01,640 --> 00:08:04,640 Speaker 1: long trip this summer. And that's what I don't want. 149 00:08:05,640 --> 00:08:08,800 Speaker 1: If I go in this weekend and change the they 150 00:08:08,840 --> 00:08:12,080 Speaker 1: put in um regular flu I want to put in 151 00:08:12,120 --> 00:08:17,280 Speaker 1: synthetic v W ninety in there. Could I take a 152 00:08:17,360 --> 00:08:20,360 Speaker 1: torque wrench as a well. I have access to that 153 00:08:20,400 --> 00:08:23,000 Speaker 1: when I take that dift cover off to make sure 154 00:08:23,000 --> 00:08:28,080 Speaker 1: it's torque correctly. The torque for the preload on the 155 00:08:28,160 --> 00:08:33,080 Speaker 1: bearing is done at the pinion flange. But that torque 156 00:08:33,360 --> 00:08:37,240 Speaker 1: or opinion preload or that that the torque of the 157 00:08:37,360 --> 00:08:42,960 Speaker 1: nut on the opinion only determines the crushed tolerance of 158 00:08:43,040 --> 00:08:46,760 Speaker 1: the bearing against the race. You don't set pinion depth 159 00:08:47,200 --> 00:08:50,760 Speaker 1: how deep. And we're talking about measurements. You know in 160 00:08:50,880 --> 00:08:53,840 Speaker 1: thousands of an inch you're not going to you're not 161 00:08:53,880 --> 00:08:56,360 Speaker 1: going to change. If you can change pinion death by 162 00:08:56,400 --> 00:08:59,360 Speaker 1: tightening the nut tighter, you've got bigger problems than than 163 00:08:59,400 --> 00:09:03,240 Speaker 1: just a one what a foul? Okay, all right, so 164 00:09:03,760 --> 00:09:07,080 Speaker 1: you know again. Um, you know, maybe they need to 165 00:09:07,080 --> 00:09:09,840 Speaker 1: pace the gears, you know, put some blue or some 166 00:09:09,840 --> 00:09:12,280 Speaker 1: some grease on their spin them. Look at them, does 167 00:09:12,280 --> 00:09:14,040 Speaker 1: it look like it's hitting each other in the middle, 168 00:09:14,360 --> 00:09:16,520 Speaker 1: that they've got the right preload on it, that they've 169 00:09:16,559 --> 00:09:19,680 Speaker 1: got you know, how did the measurements, uh, you know, 170 00:09:19,760 --> 00:09:23,040 Speaker 1: tolerate out? How to how the tolerances measure out when 171 00:09:23,040 --> 00:09:26,840 Speaker 1: they put this together? Just very very important. But first 172 00:09:26,840 --> 00:09:30,880 Speaker 1: step for me to call you kind of just inquire. Yeah, absolutely, 173 00:09:31,520 --> 00:09:34,400 Speaker 1: and I'm I'm and I'm sure listen, there's no bad 174 00:09:34,480 --> 00:09:37,880 Speaker 1: first step when you're trying to get information. I don't 175 00:09:37,920 --> 00:09:40,680 Speaker 1: care what you're working on, all right, you know, even 176 00:09:40,720 --> 00:09:43,200 Speaker 1: if you're hearing the same story over and over again. 177 00:09:43,520 --> 00:09:45,640 Speaker 1: I do it all the time. If I've got something 178 00:09:45,640 --> 00:09:48,959 Speaker 1: that I've done a hundred times and it's been a while, 179 00:09:49,080 --> 00:09:51,280 Speaker 1: like how did that go, I'll sit. I always read 180 00:09:51,320 --> 00:09:53,240 Speaker 1: the procedure. If I have my doubts, I don't care 181 00:09:53,280 --> 00:09:55,800 Speaker 1: how many times I've done it, because you know, your 182 00:09:55,800 --> 00:09:59,440 Speaker 1: mind always remembers or see something. In this particular case, 183 00:09:59,480 --> 00:10:01,560 Speaker 1: you're not the first guy to put yukon gears in 184 00:10:01,559 --> 00:10:04,719 Speaker 1: a thirteen Silverado. I would be out looking at I 185 00:10:04,720 --> 00:10:07,480 Speaker 1: would be out looking on the forms. And if twenty 186 00:10:07,520 --> 00:10:10,679 Speaker 1: guys say, yeah, the gears are a little noisier, but 187 00:10:10,800 --> 00:10:14,360 Speaker 1: they were, you know what, that's probably your answer. But 188 00:10:14,720 --> 00:10:17,080 Speaker 1: at least you do your due diligence to avoid yourself 189 00:10:17,120 --> 00:10:19,400 Speaker 1: the hassle. One of the biggest things and the cautions 190 00:10:19,440 --> 00:10:22,200 Speaker 1: I want to leave you with here, Jeremy, is that 191 00:10:22,320 --> 00:10:25,360 Speaker 1: the old rule of thumb. It's often been said that 192 00:10:25,360 --> 00:10:29,520 Speaker 1: when you replace gears, fresh bearings and and and so forth, 193 00:10:29,559 --> 00:10:33,960 Speaker 1: you overhaul the dif that that first seventy five miles 194 00:10:34,000 --> 00:10:37,440 Speaker 1: is critical on how the gears were in and if 195 00:10:37,480 --> 00:10:40,760 Speaker 1: you can if you continue to drive it and preload 196 00:10:40,880 --> 00:10:44,160 Speaker 1: and tolerances are not set correctly, you could cause an 197 00:10:44,160 --> 00:10:47,959 Speaker 1: irregular wear pattern and cause irreversible damage. So you want 198 00:10:47,960 --> 00:10:49,559 Speaker 1: to get this resolved. You want to know if it's 199 00:10:49,640 --> 00:10:53,240 Speaker 1: right or wrong right away before you continue to drive it. 200 00:10:53,679 --> 00:10:55,920 Speaker 1: Do your due diligence. Brother, call me back. You know 201 00:10:55,960 --> 00:10:57,840 Speaker 1: where you know where to find me eight five five 202 00:10:59,480 --> 00:11:01,839 Speaker 1: zero running aiming the car doctor. We're all back right 203 00:11:01,840 --> 00:11:14,199 Speaker 1: after this. For the best in car advice, give Ron 204 00:11:14,240 --> 00:11:18,000 Speaker 1: a call eight by five five zero nine nine zero zero. 205 00:11:18,360 --> 00:11:21,120 Speaker 1: Now back to run. You know I had someone this 206 00:11:21,200 --> 00:11:24,360 Speaker 1: week talk to me about buying a new car, and 207 00:11:24,360 --> 00:11:26,720 Speaker 1: they were telling me how they were afraid to buy 208 00:11:27,240 --> 00:11:30,560 Speaker 1: an internal combustion engine vehicle because electric cars will be 209 00:11:30,600 --> 00:11:33,960 Speaker 1: here in thirty years or fifteen years. We're gonna comment 210 00:11:34,000 --> 00:11:35,319 Speaker 1: on that this hour because I want to. I want 211 00:11:35,320 --> 00:11:37,360 Speaker 1: to bring that up. I thought that was an interesting perspective. 212 00:11:37,400 --> 00:11:39,199 Speaker 1: I hadn't thought of it. But right now, let's get 213 00:11:39,200 --> 00:11:42,080 Speaker 1: over to Jim in Michigan sixty two Chevy Nova and 214 00:11:42,320 --> 00:11:44,319 Speaker 1: trying to get the front passenger hub apart. Jim, I'll 215 00:11:44,320 --> 00:11:47,360 Speaker 1: give you fifty bucks for its sight unstane. I think 216 00:11:47,440 --> 00:11:51,480 Speaker 1: we'll almost consider that a down payment run. So thank 217 00:11:51,520 --> 00:11:57,000 Speaker 1: you for your wisdom. This is one of those uh 218 00:11:57,400 --> 00:12:01,760 Speaker 1: fifty a week for five years. Well, yeah, let's work 219 00:12:01,760 --> 00:12:04,079 Speaker 1: on the interest rate. But what kind of probably not 220 00:12:04,120 --> 00:12:07,320 Speaker 1: don't enough? So how can I help you my phone? Yeah, 221 00:12:07,400 --> 00:12:10,240 Speaker 1: this has been one of those multi year restoration projects 222 00:12:10,240 --> 00:12:14,320 Speaker 1: were on. I lafely lost my brakes about two years ago, 223 00:12:14,400 --> 00:12:17,080 Speaker 1: so we just kind of parked it inside. Did you 224 00:12:17,120 --> 00:12:21,120 Speaker 1: know interior other parts of the car. I replaced the 225 00:12:21,200 --> 00:12:25,280 Speaker 1: wheel and the tire on the front passenger side a 226 00:12:25,320 --> 00:12:28,880 Speaker 1: couple of days ago. The old wheel came off. The 227 00:12:28,920 --> 00:12:31,760 Speaker 1: new one went on smoothly. But when I went to 228 00:12:31,880 --> 00:12:35,520 Speaker 1: spin the tire, it did not rotate. It did not spin. 229 00:12:36,880 --> 00:12:39,640 Speaker 1: I took the tire of the wheel off, whacked with 230 00:12:39,720 --> 00:12:43,240 Speaker 1: a hammer a few times, applied a little bit of heat, 231 00:12:43,760 --> 00:12:48,800 Speaker 1: and still no rotation, no spinning. It does have the 232 00:12:48,920 --> 00:12:52,440 Speaker 1: UM I guess the brake shoes or brake pads, and 233 00:12:52,480 --> 00:12:54,720 Speaker 1: I'm not sure if maybe some rust is maybe just 234 00:12:54,760 --> 00:13:00,960 Speaker 1: accompulated and preventing that hug from spinning. Yeah, I would 235 00:13:00,960 --> 00:13:07,480 Speaker 1: agree this is a break drum vehicle. Still correct, Yes, rum? 236 00:13:07,760 --> 00:13:11,480 Speaker 1: Can you can you get the center cap for the 237 00:13:11,480 --> 00:13:16,080 Speaker 1: wheel bearing off? I probably could, yes, And let's just 238 00:13:16,120 --> 00:13:20,920 Speaker 1: talk this out. What would be the danger in taking 239 00:13:20,920 --> 00:13:23,800 Speaker 1: the center cap off? And I'm just trying to think 240 00:13:23,840 --> 00:13:27,400 Speaker 1: of the parts we're gonna sacrifice here taking the center 241 00:13:27,480 --> 00:13:33,960 Speaker 1: cap off, the outer bearing off, and um, how would 242 00:13:33,960 --> 00:13:35,800 Speaker 1: we do this? Lower the car on the ground. I 243 00:13:35,840 --> 00:13:38,160 Speaker 1: want to use the weight of the car against the 244 00:13:38,200 --> 00:13:42,040 Speaker 1: brake shoes probably rusted to the drum. We're assuming the 245 00:13:42,400 --> 00:13:45,480 Speaker 1: shoes have rusted to the drum. That's kind of what 246 00:13:45,520 --> 00:13:48,400 Speaker 1: I'm thinking of. And I'm I'm just saying to myself 247 00:13:48,440 --> 00:13:52,880 Speaker 1: with the weight of the vehicle rocking against the shoes 248 00:13:54,400 --> 00:13:59,640 Speaker 1: cause them to pop and release. Okay, and the only 249 00:13:59,679 --> 00:14:03,640 Speaker 1: way I know to do that is to load against 250 00:14:03,679 --> 00:14:07,440 Speaker 1: the spindle, the hub, the bearing. But you know, we 251 00:14:07,480 --> 00:14:11,360 Speaker 1: stand the chance to ruin a few things here, namely bearings, 252 00:14:11,440 --> 00:14:15,400 Speaker 1: namely the brake, shoes themselves. Uh, the way the whole 253 00:14:15,440 --> 00:14:20,560 Speaker 1: down springs are affixiated, you know, et cetera. Um, I'm 254 00:14:20,600 --> 00:14:23,400 Speaker 1: willing to sacrifice the shoes that that part will not 255 00:14:23,440 --> 00:14:27,440 Speaker 1: be a problem. What about can you get to the 256 00:14:27,440 --> 00:14:30,640 Speaker 1: there's gotta be a there's gotta be a um A 257 00:14:30,640 --> 00:14:34,800 Speaker 1: self adjuster slot right through the backing plate. I believe 258 00:14:34,840 --> 00:14:37,760 Speaker 1: there is. Yes, What if we back that self adjuster 259 00:14:37,960 --> 00:14:42,880 Speaker 1: all the way off? And if if we back the 260 00:14:42,920 --> 00:14:46,400 Speaker 1: self adjuster all the way off, is there a and 261 00:14:46,560 --> 00:14:49,760 Speaker 1: I don't think there isn't sixty two? Is there an 262 00:14:49,800 --> 00:14:52,400 Speaker 1: inspection plug of some kind where we could look at 263 00:14:52,440 --> 00:14:55,480 Speaker 1: the depth of the shoes where we see the shoes 264 00:14:55,560 --> 00:15:00,240 Speaker 1: physically move away from the drum? I don't think. I 265 00:15:00,280 --> 00:15:05,360 Speaker 1: don't think. So. You know, if we back off the 266 00:15:05,440 --> 00:15:09,040 Speaker 1: star wheel self adjuster, does it look like you know 267 00:15:09,040 --> 00:15:12,440 Speaker 1: what's gonna happen? Is the self adjuster is likely going 268 00:15:12,600 --> 00:15:17,160 Speaker 1: to get sloppy right the shoes. If the shoes are 269 00:15:17,280 --> 00:15:20,840 Speaker 1: rusted against the drum, then the self adjuster is gonna 270 00:15:20,880 --> 00:15:24,800 Speaker 1: get sloppy where it wedges itself between the two shoes 271 00:15:24,840 --> 00:15:27,320 Speaker 1: at the bottom, and that that adjuster is just going 272 00:15:27,360 --> 00:15:29,680 Speaker 1: to eventually pick up enough slop. That was a bit, 273 00:15:29,760 --> 00:15:33,080 Speaker 1: you know, kind of just sort of wobble around. But 274 00:15:33,720 --> 00:15:36,240 Speaker 1: if that's the case, then we know the shoes are 275 00:15:36,280 --> 00:15:40,200 Speaker 1: frozen against the drum, and we know what we've got 276 00:15:40,200 --> 00:15:42,120 Speaker 1: to do. But at least if you get the adjuster 277 00:15:42,240 --> 00:15:45,520 Speaker 1: out of the way, maybe spring tension. I mean, you're 278 00:15:45,520 --> 00:15:48,320 Speaker 1: gonna have to overhaul the front brakes anyway at this point. 279 00:15:48,360 --> 00:15:51,880 Speaker 1: If the shoes are really frozen to the drum. You know, 280 00:15:51,920 --> 00:15:54,960 Speaker 1: the question is the least amount of damage. Heat's not 281 00:15:55,040 --> 00:15:58,160 Speaker 1: a bad idea. I don't think you could generate enough 282 00:15:58,240 --> 00:16:02,280 Speaker 1: without doing their damage to other break components. I'm trying 283 00:16:02,280 --> 00:16:05,720 Speaker 1: to get this thing apart as delicately as I can. Uh, 284 00:16:05,760 --> 00:16:08,240 Speaker 1: that's why I'm wondering the weight of the vehicle, you know. 285 00:16:08,240 --> 00:16:11,320 Speaker 1: And you my guess is if you pull the outer bearing, 286 00:16:11,360 --> 00:16:15,040 Speaker 1: that gives the drum the ability to cock itself. Uh, 287 00:16:15,080 --> 00:16:17,720 Speaker 1: you know, I would probably put the nut back on 288 00:16:18,960 --> 00:16:23,480 Speaker 1: so that God forbid, the drum can't somehow slide off 289 00:16:23,840 --> 00:16:25,440 Speaker 1: if the car would have got this swaying the drum 290 00:16:25,480 --> 00:16:29,160 Speaker 1: go that way, and obviously be careful. Jack stands or something, 291 00:16:29,200 --> 00:16:32,560 Speaker 1: maybe a jack stands or or some sort of safety 292 00:16:32,880 --> 00:16:36,240 Speaker 1: support that if the wheel fell, it's gonna fall on 293 00:16:36,280 --> 00:16:39,600 Speaker 1: the jack stand before it hits the ground, so to speak. 294 00:16:40,080 --> 00:16:43,040 Speaker 1: Um maybe a floor jack under the under the under 295 00:16:43,040 --> 00:16:45,880 Speaker 1: the cradle with a two by four two inches down. 296 00:16:46,000 --> 00:16:47,760 Speaker 1: It doesn't it's not gonna take much to move. If 297 00:16:47,800 --> 00:16:50,200 Speaker 1: you if you can get the car to change pitched 298 00:16:50,680 --> 00:16:53,160 Speaker 1: an inch, it's probably gonna pop the drum. I just 299 00:16:53,160 --> 00:16:54,840 Speaker 1: got a feeling when you put some weight on it 300 00:16:54,880 --> 00:16:58,240 Speaker 1: and there's nothing holding the shoes against the drum, it's 301 00:16:58,320 --> 00:17:02,800 Speaker 1: going to just, you know, snap, just a quick release 302 00:17:02,840 --> 00:17:08,280 Speaker 1: and away it goes. Yeah, okay, you know, let's give 303 00:17:08,320 --> 00:17:11,440 Speaker 1: that a shot. If that doesn't work. Last ditch before 304 00:17:11,440 --> 00:17:15,120 Speaker 1: I tell you to take the drum off is from 305 00:17:15,160 --> 00:17:16,920 Speaker 1: the top. You know, get it up, get the wheel 306 00:17:16,920 --> 00:17:21,000 Speaker 1: and the tire off. Soak start soaking from the top, 307 00:17:21,160 --> 00:17:24,439 Speaker 1: lip p B blaster, just get as much PB. It's 308 00:17:24,480 --> 00:17:26,840 Speaker 1: gonna make a mess. Of things. Put a drip pan underneath, 309 00:17:27,119 --> 00:17:29,919 Speaker 1: try and get some PB around the lip of the 310 00:17:30,000 --> 00:17:33,000 Speaker 1: drum as it sits against the backing plate and let 311 00:17:33,000 --> 00:17:35,720 Speaker 1: it soak. It might just be able to get enough 312 00:17:35,760 --> 00:17:40,040 Speaker 1: creep action that you can eventually work it free that 313 00:17:40,119 --> 00:17:42,320 Speaker 1: way too. But p B blaster is really great in 314 00:17:42,320 --> 00:17:46,200 Speaker 1: a situation like this. It tends to eat, yeah, the 315 00:17:46,520 --> 00:17:49,160 Speaker 1: big pill right, the big pail. And then when none 316 00:17:49,200 --> 00:17:50,880 Speaker 1: of this works, then I'm gonna tell you to split 317 00:17:50,920 --> 00:17:54,040 Speaker 1: the ball joints at the knuckle and you know, support 318 00:17:54,040 --> 00:17:56,360 Speaker 1: the control arm, get the get the knuckle and the 319 00:17:56,359 --> 00:17:58,960 Speaker 1: break drum assembly off and let's work on it in 320 00:17:59,040 --> 00:18:01,200 Speaker 1: advice so we don't have to you know, we don't 321 00:18:01,200 --> 00:18:02,800 Speaker 1: have to worry about the rest of the vehicle. I'm 322 00:18:02,840 --> 00:18:06,359 Speaker 1: just thinking you've got bigger issues here. Um, if you 323 00:18:06,400 --> 00:18:09,600 Speaker 1: have to sacrifice the drum, maybe take it to a 324 00:18:09,640 --> 00:18:12,800 Speaker 1: machine shop and have them machine the drum off, save 325 00:18:12,880 --> 00:18:15,480 Speaker 1: the backing plate and the spindle and uh, you know, 326 00:18:15,520 --> 00:18:17,680 Speaker 1: I think that will come out better for you. All right, sir, 327 00:18:18,760 --> 00:18:21,000 Speaker 1: all right, very well, you'd be you'd be well and 328 00:18:21,040 --> 00:18:23,720 Speaker 1: good luck. Let us know what happens. UM sixty two 329 00:18:23,760 --> 00:18:25,800 Speaker 1: Chevy two is Novas they're just neat little cars. Not 330 00:18:25,920 --> 00:18:27,919 Speaker 1: enough of them left, obviously, I'd like to hear how 331 00:18:27,960 --> 00:18:30,639 Speaker 1: this one comes out. Hey, coming up next, a C 332 00:18:30,880 --> 00:18:32,960 Speaker 1: one oh one and a little bit more chucking Kaide 333 00:18:32,960 --> 00:18:34,520 Speaker 1: from All is going to stop by the garage and 334 00:18:34,560 --> 00:18:37,080 Speaker 1: talk to us all about air conditioning. What we need 335 00:18:37,119 --> 00:18:39,320 Speaker 1: to know. Whether you're a repair shop or a consumer. 336 00:18:39,520 --> 00:18:41,159 Speaker 1: This is the place to be. I'm Ronini and the 337 00:18:41,200 --> 00:19:01,040 Speaker 1: Car Doctor. We're back right after this colcome back n 338 00:19:01,080 --> 00:19:02,760 Speaker 1: a name of the car doctorate. You know, our next 339 00:19:02,800 --> 00:19:06,600 Speaker 1: guest has such a long title because of his involvement 340 00:19:06,600 --> 00:19:08,560 Speaker 1: in the industry. We actually had to short it down 341 00:19:08,560 --> 00:19:10,920 Speaker 1: to we First it got down to a paragraph, and 342 00:19:10,920 --> 00:19:12,239 Speaker 1: then we took it down to a sentence, and then 343 00:19:12,240 --> 00:19:14,240 Speaker 1: we've got it down to a couple of words. Chuck 344 00:19:14,320 --> 00:19:16,520 Speaker 1: kin Kaid has been around the automotive industry for such 345 00:19:16,560 --> 00:19:18,760 Speaker 1: a long time as a product manager, and he's in 346 00:19:18,840 --> 00:19:21,639 Speaker 1: charge of engineering shop equipment for Mala Corporation. We're just 347 00:19:21,800 --> 00:19:23,960 Speaker 1: really glad to have him here with us today. Chuck, 348 00:19:24,000 --> 00:19:29,639 Speaker 1: Welcome to boards, sir, Hey, thanks, air conditioning systems and 349 00:19:29,720 --> 00:19:32,880 Speaker 1: cars and trucks. You know, it's often been said that 350 00:19:33,400 --> 00:19:37,080 Speaker 1: somebody might skimp out and not do the complete break job. 351 00:19:37,200 --> 00:19:40,120 Speaker 1: They might do a cheaper royal change. They might put 352 00:19:40,840 --> 00:19:43,320 Speaker 1: you know, tires, it won't last as long on the car. 353 00:19:43,359 --> 00:19:47,080 Speaker 1: But boy, when air conditioning doesn't work, it's over right, 354 00:19:48,200 --> 00:19:53,200 Speaker 1: every upset. Everybody's upset. Um. How has and it's it's 355 00:19:53,320 --> 00:19:56,000 Speaker 1: changed so much. Take us back real quick if you can, 356 00:19:56,359 --> 00:19:59,480 Speaker 1: how have a c systems and cars and trucks involved. 357 00:20:00,280 --> 00:20:03,159 Speaker 1: You know, back in the sixties a Cadillac with our 358 00:20:03,280 --> 00:20:05,760 Speaker 1: twelve had a capacity of over four and a half 359 00:20:05,760 --> 00:20:09,320 Speaker 1: pounds um. And how does that evolve fast forward to 360 00:20:09,320 --> 00:20:14,040 Speaker 1: today's vehicles. Yeah, so you know, the system sizes have changed. 361 00:20:14,200 --> 00:20:16,919 Speaker 1: We do smaller systems and you know with that, of 362 00:20:16,960 --> 00:20:20,600 Speaker 1: course comes new challenges. But you know you've got smaller components. 363 00:20:20,680 --> 00:20:24,200 Speaker 1: You uh, you've got uh less room in the vehicle, 364 00:20:24,320 --> 00:20:27,239 Speaker 1: you've got less airflow. Um. You know, there's been a 365 00:20:27,240 --> 00:20:29,640 Speaker 1: lot of a lot of changes through the years. Uh. 366 00:20:30,040 --> 00:20:35,280 Speaker 1: You know, so UM I think, uh, you know it's 367 00:20:35,280 --> 00:20:38,720 Speaker 1: important that you know, you people understand that. You know, 368 00:20:38,800 --> 00:20:41,560 Speaker 1: system system sizes are actually a lot smaller these days, 369 00:20:41,640 --> 00:20:45,080 Speaker 1: and so you know it drives the need for higher accuracy, 370 00:20:45,400 --> 00:20:48,040 Speaker 1: you know, really because you know, if you overcharge or 371 00:20:48,119 --> 00:20:50,320 Speaker 1: under charge, like like you say, a four and a 372 00:20:50,320 --> 00:20:54,000 Speaker 1: half pound system a little bit. Yeah, you generally you're okay, right, 373 00:20:54,080 --> 00:20:55,959 Speaker 1: you might want to top it off, it might make 374 00:20:55,960 --> 00:20:58,480 Speaker 1: it a little cooler. But these days, yeah, you can't 375 00:20:58,520 --> 00:21:02,359 Speaker 1: really do that anymore. If that's sixty six Caddy lost 376 00:21:02,359 --> 00:21:06,159 Speaker 1: eight ounces of refrigerant, what was that that was? It 377 00:21:06,240 --> 00:21:09,760 Speaker 1: was less than a quarter capacity, right, it wasn't capacity, 378 00:21:09,760 --> 00:21:12,080 Speaker 1: it was it was still cold in those cars. I 379 00:21:12,119 --> 00:21:15,399 Speaker 1: remember those cars. I wrote in those cars. Uh. You know, 380 00:21:15,760 --> 00:21:19,359 Speaker 1: you know, you get a modern day vehicle that you know, 381 00:21:19,480 --> 00:21:23,720 Speaker 1: something a twenty sixteen or seventeen anything, and it loses 382 00:21:23,760 --> 00:21:26,920 Speaker 1: eight ounces of refrigerant. That's that could be that could 383 00:21:26,960 --> 00:21:29,920 Speaker 1: be two thirds the charge. The car basically blows hot air, 384 00:21:31,280 --> 00:21:34,800 Speaker 1: yeah exactly. Yeah, so you have to get more accurate 385 00:21:34,840 --> 00:21:37,520 Speaker 1: with it, right, So so you know, it goes into 386 00:21:37,680 --> 00:21:39,760 Speaker 1: you know, the equipment that you use and things like this. 387 00:21:39,920 --> 00:21:42,720 Speaker 1: You know, we you see use gauges and engage sets 388 00:21:42,760 --> 00:21:44,480 Speaker 1: and that type of thing, and that moved into the 389 00:21:44,480 --> 00:21:47,480 Speaker 1: equipment space and now the equipments. You know, we have 390 00:21:47,600 --> 00:21:49,879 Speaker 1: new standards and different things that we do to make 391 00:21:49,920 --> 00:21:53,080 Speaker 1: sure these these are really accurate when they charge and 392 00:21:53,080 --> 00:21:54,680 Speaker 1: and so on and so forth. You know, so it's 393 00:21:54,680 --> 00:21:58,560 Speaker 1: been uh, it's quite a transition, what you know, if 394 00:21:58,600 --> 00:22:01,960 Speaker 1: you can you know, not not the whole story, just 395 00:22:02,040 --> 00:22:05,000 Speaker 1: maybe the first paragraph. But we know we went from 396 00:22:05,040 --> 00:22:08,160 Speaker 1: our twelve to one thirty four A. You know, obviously 397 00:22:08,200 --> 00:22:12,200 Speaker 1: ozone issues, and now we're transitioning from one thirty four 398 00:22:12,280 --> 00:22:17,040 Speaker 1: to one two three four YF why ozone issues again? 399 00:22:17,080 --> 00:22:21,080 Speaker 1: The environment again? No, yeah, that's it's actually the environment. 400 00:22:21,160 --> 00:22:24,480 Speaker 1: So you're absolutely right. So when we transition from our twelve, 401 00:22:24,560 --> 00:22:29,160 Speaker 1: that was really had to do with the ozone depletion, right, So, um, 402 00:22:29,520 --> 00:22:32,360 Speaker 1: our our twelve is really bad for the environment. So 403 00:22:32,720 --> 00:22:34,919 Speaker 1: you know, we need that ozone in our stratosphere to 404 00:22:35,200 --> 00:22:38,320 Speaker 1: you know, really protect us and things. And so now 405 00:22:38,560 --> 00:22:41,359 Speaker 1: you know what didn't happen when we transition. So we 406 00:22:41,520 --> 00:22:46,720 Speaker 1: we transition from our twelve to one, and you know, 407 00:22:47,640 --> 00:22:50,720 Speaker 1: now we're getting into what's called the global warming potential, right, 408 00:22:50,760 --> 00:22:54,639 Speaker 1: so our twelve is also bad for global warming potential. 409 00:22:54,720 --> 00:22:57,879 Speaker 1: So this is a CEO two has a global warming 410 00:22:57,920 --> 00:23:00,920 Speaker 1: potential of one, So we use that as a rep prints. Okay, 411 00:23:01,200 --> 00:23:03,959 Speaker 1: so we say c O two is the one, our 412 00:23:04,080 --> 00:23:08,960 Speaker 1: twelve is ten thousand, nine hundreds. So so one pound 413 00:23:09,240 --> 00:23:13,119 Speaker 1: of our twelve would is really you know what is 414 00:23:13,160 --> 00:23:16,639 Speaker 1: that five tons of c O two equivalents in the 415 00:23:16,680 --> 00:23:21,000 Speaker 1: atmosphere one four A UM. It is also bad, not 416 00:23:21,080 --> 00:23:25,080 Speaker 1: quite as bad. It's it's actually fourteen thirty so almost 417 00:23:25,080 --> 00:23:28,560 Speaker 1: a ton for every pound that you release. And so 418 00:23:28,600 --> 00:23:33,880 Speaker 1: now we're transitioning to one four y U and that's 419 00:23:33,880 --> 00:23:36,800 Speaker 1: got a global warm potential of four so that's it's 420 00:23:36,840 --> 00:23:40,320 Speaker 1: literally ninety seven percent better than one thirty four A. 421 00:23:40,440 --> 00:23:42,199 Speaker 1: So that's really driving a lot of changes in the 422 00:23:42,200 --> 00:23:44,280 Speaker 1: industry right now. I didn't realize our twelve is that 423 00:23:44,359 --> 00:23:46,920 Speaker 1: bad or twelve is like a bazooka shot to the ozone. 424 00:23:47,080 --> 00:23:50,760 Speaker 1: Let's just blow a hole in in in the atmosphere. Yeah. 425 00:23:50,840 --> 00:23:52,840 Speaker 1: So the O zone, yeah you want to talk O 426 00:23:52,960 --> 00:23:55,520 Speaker 1: zone one three four A is way better for ozone 427 00:23:55,560 --> 00:23:58,480 Speaker 1: than our twelve used to be. It's not zero, but 428 00:23:58,520 --> 00:24:01,560 Speaker 1: it's it's it's way better to our twelve. If our 429 00:24:01,600 --> 00:24:04,080 Speaker 1: twelve is a one one four A is like zero 430 00:24:04,119 --> 00:24:07,159 Speaker 1: is your point zero zero zero one uh five, you 431 00:24:07,200 --> 00:24:11,680 Speaker 1: know something like this. So from that standpoint, yeah, it's 432 00:24:12,000 --> 00:24:15,040 Speaker 1: I think we've got the ozone problem. Okay with one 433 00:24:15,400 --> 00:24:18,119 Speaker 1: four A and with YF. But what we need to 434 00:24:18,160 --> 00:24:20,399 Speaker 1: get a handle on is the global warming. So the 435 00:24:20,440 --> 00:24:24,720 Speaker 1: CEO two gases and warming the planet. Um. And so 436 00:24:25,240 --> 00:24:28,440 Speaker 1: you know there's more A C systems these days. Um. 437 00:24:28,480 --> 00:24:30,560 Speaker 1: You know, we we have more people, so on and 438 00:24:30,560 --> 00:24:33,760 Speaker 1: so forth. So uh, you know, moving to a lower 439 00:24:33,840 --> 00:24:37,600 Speaker 1: g wt refrigerant just just something that's gonna make sense 440 00:24:37,640 --> 00:24:40,560 Speaker 1: for us. So when you look at a modern vehicle, 441 00:24:40,760 --> 00:24:42,480 Speaker 1: and for those of you just joining us, we're talking 442 00:24:42,520 --> 00:24:45,560 Speaker 1: to Chuck in Kid from Mala Corporation about air conditioning, 443 00:24:46,440 --> 00:24:49,919 Speaker 1: when you look at a modern day vehicle, Chuck, you 444 00:24:49,960 --> 00:24:52,560 Speaker 1: know it's it's not that sixty six caddy with a 445 00:24:52,560 --> 00:24:55,320 Speaker 1: four and a half pound system, it's a one pound. 446 00:24:55,640 --> 00:25:00,960 Speaker 1: Typical system capacity today is sixteen ounces are less the 447 00:25:01,119 --> 00:25:03,439 Speaker 1: shop that's you know, and the reason we went to 448 00:25:03,480 --> 00:25:06,040 Speaker 1: all this is right. We we need the grill area. 449 00:25:06,200 --> 00:25:08,960 Speaker 1: The design of the vehicle has affective components, and we're 450 00:25:08,960 --> 00:25:11,920 Speaker 1: trying to make everything more compact. That's a given. But 451 00:25:12,080 --> 00:25:14,680 Speaker 1: the shops that are out there, and I want you 452 00:25:14,720 --> 00:25:17,960 Speaker 1: to speak directly to this, that are trying to charge 453 00:25:18,040 --> 00:25:23,040 Speaker 1: air conditioning new old whatever, without a machine, how can 454 00:25:23,080 --> 00:25:28,520 Speaker 1: they be accurate it's really difficult. UM. Yeah. So you know, we, 455 00:25:28,920 --> 00:25:30,960 Speaker 1: you know, not just us, but a lot of in 456 00:25:30,960 --> 00:25:34,400 Speaker 1: the industry spent a lot of time really tuning these systems. 457 00:25:34,440 --> 00:25:36,800 Speaker 1: And there's new standards that we have to meet today. 458 00:25:37,160 --> 00:25:40,200 Speaker 1: If you look back in UM the R twelve days, UM. 459 00:25:40,560 --> 00:25:43,280 Speaker 1: You know, the the j so f A has standards 460 00:25:43,280 --> 00:25:46,040 Speaker 1: for equipment and uh used to be j I think 461 00:25:46,040 --> 00:25:50,199 Speaker 1: it's standards, but you know those standards for that we 462 00:25:50,200 --> 00:25:53,720 Speaker 1: were under, they really have nothing for the efficiency of 463 00:25:53,720 --> 00:25:56,840 Speaker 1: the recovery or the charge accuracy, right because of the 464 00:25:56,880 --> 00:25:59,760 Speaker 1: systems were so big. Be fast forward to two thousands 465 00:26:00,040 --> 00:26:04,480 Speaker 1: and as the standard came out and that that forced 466 00:26:04,560 --> 00:26:10,159 Speaker 1: us to do recovery in every case half oun charge accuracy. 467 00:26:10,400 --> 00:26:12,879 Speaker 1: UM added some other things like you know, you can't 468 00:26:12,920 --> 00:26:15,760 Speaker 1: cross contaminate, so if you know, you know, uh or 469 00:26:15,840 --> 00:26:17,960 Speaker 1: if you know, but if you know, I'm sure you know. 470 00:26:18,040 --> 00:26:20,320 Speaker 1: But tag oil and poe oil, you have to be 471 00:26:20,359 --> 00:26:23,280 Speaker 1: careful if you get an electrically driven compressor. You don't 472 00:26:23,320 --> 00:26:26,240 Speaker 1: want that oil to be conductive. Uh. You know that 473 00:26:26,280 --> 00:26:29,600 Speaker 1: can cause fires and electrical issues in this so UM. 474 00:26:29,640 --> 00:26:32,280 Speaker 1: So there's some standards that were put in there, and 475 00:26:32,320 --> 00:26:34,440 Speaker 1: then now we've got a new standard that we've got 476 00:26:34,440 --> 00:26:38,399 Speaker 1: to meet, which is h J seven for r F, I, 477 00:26:38,480 --> 00:26:43,560 Speaker 1: D and J, which is for the wife equipment in whole. 478 00:26:44,200 --> 00:26:46,359 Speaker 1: And that's due to the there's just the changes in 479 00:26:46,440 --> 00:26:50,040 Speaker 1: the refrigerant um. The playability of the refrigement was a 480 00:26:50,040 --> 00:26:52,439 Speaker 1: big driver for a lot of that. Right, you know 481 00:26:53,040 --> 00:26:55,440 Speaker 1: it's been said, and I'm gonna, I'm gonna, I'm gonna 482 00:26:55,480 --> 00:26:57,159 Speaker 1: put it here before we take the plus, Chuck, I 483 00:26:57,119 --> 00:26:59,480 Speaker 1: want to hold you over another segment. A C is 484 00:26:59,480 --> 00:27:04,359 Speaker 1: assisted of precise measurement and accuracy, and I want to 485 00:27:04,400 --> 00:27:06,560 Speaker 1: talk about how you put that into a machine and 486 00:27:06,640 --> 00:27:08,520 Speaker 1: make that work. Stay right where you are, Chuck and 487 00:27:08,600 --> 00:27:11,359 Speaker 1: Kaid Mala Corporation on Ronanini in the Car Doctor. We'll 488 00:27:11,359 --> 00:27:20,560 Speaker 1: both be back right after this. Don't go away, Welcome 489 00:27:20,560 --> 00:27:23,119 Speaker 1: back the car Doctor here with Chuck in Kid, product 490 00:27:23,119 --> 00:27:27,280 Speaker 1: manager and Equipment Engineering Equipment UH, Workshop manager for the 491 00:27:27,440 --> 00:27:31,680 Speaker 1: Automotiva after market at Mala and Um, Chuck, your your 492 00:27:31,680 --> 00:27:36,280 Speaker 1: title changes by the way, by the minute. I'm sorry. Uh. 493 00:27:36,320 --> 00:27:40,159 Speaker 1: You know there's far too many cars out there that 494 00:27:40,800 --> 00:27:43,160 Speaker 1: you know you'll drive along in the A C. It'll 495 00:27:43,160 --> 00:27:45,080 Speaker 1: blow cold out the left side and hot out the 496 00:27:45,160 --> 00:27:49,320 Speaker 1: right and to the layman or even to some mechanics, 497 00:27:49,320 --> 00:27:52,000 Speaker 1: they'll think that, gee, there's a problem with blend doors 498 00:27:52,440 --> 00:27:55,720 Speaker 1: or maybe the controls are not working properly. But in 499 00:27:55,720 --> 00:27:59,760 Speaker 1: a lot of cases it's a charge issue. And you know, 500 00:27:59,760 --> 00:28:03,000 Speaker 1: we're talking about being off by four ounces. The system 501 00:28:03,040 --> 00:28:06,800 Speaker 1: is not properly charged. It does that. You need a machine. 502 00:28:06,840 --> 00:28:09,640 Speaker 1: You absolutely have to charge by a machine. It's it's 503 00:28:09,680 --> 00:28:12,800 Speaker 1: the law in a lot of cases. But you know, 504 00:28:13,680 --> 00:28:17,640 Speaker 1: speak to that precision, that that that accuracy, that's that's 505 00:28:17,640 --> 00:28:21,080 Speaker 1: a standard that's they don't they don't really let go of, 506 00:28:21,240 --> 00:28:25,520 Speaker 1: do they now? And you're right, right, I mean exactly. 507 00:28:25,520 --> 00:28:26,920 Speaker 1: I mean a lot of times it would be a 508 00:28:26,920 --> 00:28:30,040 Speaker 1: blend or but it could also be under charging, right, 509 00:28:30,119 --> 00:28:33,879 Speaker 1: And so there's consequences to under charging or overcharging the system. 510 00:28:34,160 --> 00:28:36,920 Speaker 1: Overcharging could damage a compressor. There's all kinds of different 511 00:28:36,920 --> 00:28:40,120 Speaker 1: things that could happen, and it really depends on the vehicle. Um. 512 00:28:40,200 --> 00:28:43,600 Speaker 1: But yeah, I mean, you absolutely need a certified machine. 513 00:28:43,640 --> 00:28:48,520 Speaker 1: All these sort of units are certified. They need testing standards, 514 00:28:48,840 --> 00:28:51,680 Speaker 1: and you're really you're really doing the customers a disservice 515 00:28:51,720 --> 00:28:54,120 Speaker 1: if you're not using machine on a modern vehicle. Uh 516 00:28:54,640 --> 00:28:56,840 Speaker 1: you know, you know, we take a lot of factors 517 00:28:56,840 --> 00:29:00,680 Speaker 1: in new account temperature pressures, weights, COUMP and say factors 518 00:29:00,680 --> 00:29:02,480 Speaker 1: and things like this so that you can get a 519 00:29:02,480 --> 00:29:05,400 Speaker 1: good service, in a repeatable service out of it. And 520 00:29:05,560 --> 00:29:07,920 Speaker 1: if you're doing that mannually or with especially with older 521 00:29:07,960 --> 00:29:11,280 Speaker 1: equipment which really just doesn't have those kind of standards, um, 522 00:29:11,320 --> 00:29:13,960 Speaker 1: you know, it's tough to get that accuracy of the unit. 523 00:29:15,160 --> 00:29:18,800 Speaker 1: One of the things, one of the things that I 524 00:29:18,840 --> 00:29:23,040 Speaker 1: love the way my Mama machine works is that and 525 00:29:23,080 --> 00:29:25,280 Speaker 1: in comparison to some of the older machines we used 526 00:29:25,320 --> 00:29:28,680 Speaker 1: to run through the shop, is that the Mala sort 527 00:29:28,680 --> 00:29:31,560 Speaker 1: of gives you training on the job. You know, you 528 00:29:31,560 --> 00:29:33,920 Speaker 1: you walk through an automatic sequence. It tells you, now, 529 00:29:33,960 --> 00:29:35,640 Speaker 1: I'm gonna do this, how does this look? I'm gonna 530 00:29:35,680 --> 00:29:37,120 Speaker 1: do that? How does that look? You know? Now we 531 00:29:37,120 --> 00:29:39,880 Speaker 1: need to do this, and it teaches you the process 532 00:29:40,640 --> 00:29:43,480 Speaker 1: and asks you the question at the same time, and 533 00:29:44,040 --> 00:29:46,200 Speaker 1: not to mention the display is very nice. Can that 534 00:29:46,240 --> 00:29:48,520 Speaker 1: thing get like YouTube channel? I mean, can I can 535 00:29:48,560 --> 00:29:50,800 Speaker 1: I get like bugs buttons? You know it's like sometimes 536 00:29:50,840 --> 00:29:52,680 Speaker 1: you want to watch TV. You're doing a c service, 537 00:29:52,720 --> 00:29:57,080 Speaker 1: but um uh yeah, we could do that, but yeah, 538 00:29:57,520 --> 00:29:59,760 Speaker 1: we we tend not to. But yeah, you're right. We 539 00:30:00,160 --> 00:30:03,160 Speaker 1: user manuals in there right in the interface. And um, 540 00:30:03,240 --> 00:30:05,240 Speaker 1: you know, we always tell customers, you know, follow the 541 00:30:05,280 --> 00:30:07,680 Speaker 1: instructions on this greet and that's really what you have 542 00:30:07,760 --> 00:30:10,200 Speaker 1: to do, and you know we walk you through it. 543 00:30:10,240 --> 00:30:12,640 Speaker 1: You know. So there's things get more complex, you know. 544 00:30:12,680 --> 00:30:15,520 Speaker 1: We obviously we put more technology into these units, but 545 00:30:15,680 --> 00:30:17,640 Speaker 1: part of the reasons to do that is really to 546 00:30:17,680 --> 00:30:20,480 Speaker 1: make life easier for the technician. Right, So you know 547 00:30:20,680 --> 00:30:23,280 Speaker 1: it sounds more complicated with touch screens and things like this, 548 00:30:23,360 --> 00:30:25,640 Speaker 1: but the point of the technology is to make you 549 00:30:26,000 --> 00:30:28,720 Speaker 1: make it easier to use, make life easier, uh, for 550 00:30:28,800 --> 00:30:31,200 Speaker 1: the technician. So you know, well, we do things like 551 00:30:31,280 --> 00:30:33,960 Speaker 1: we have WiFi in our enclosure that gives us you know, 552 00:30:34,000 --> 00:30:36,600 Speaker 1: we can network print full page reports, or we have 553 00:30:36,640 --> 00:30:38,600 Speaker 1: a phone mapp you can be across the shop or 554 00:30:38,600 --> 00:30:40,440 Speaker 1: at lunch and you you get a push notification note my 555 00:30:40,480 --> 00:30:45,040 Speaker 1: services done, or monitor the pressures while you're doing the service. Um, 556 00:30:45,080 --> 00:30:47,520 Speaker 1: you know, we we could also give us some advantages 557 00:30:47,560 --> 00:30:50,160 Speaker 1: for like diagn diagnosing machines. If you have a problem 558 00:30:50,160 --> 00:30:52,840 Speaker 1: in the in the field, we can remote into those machines. 559 00:30:52,920 --> 00:30:55,840 Speaker 1: We can take over control. We can do live training 560 00:30:55,840 --> 00:31:00,080 Speaker 1: in some cases UM diagnosed the machine. UM actually a 561 00:31:00,080 --> 00:31:02,440 Speaker 1: lot of cases prevent the need to have to send 562 00:31:02,760 --> 00:31:05,760 Speaker 1: service providers out. And and I really like it to 563 00:31:05,800 --> 00:31:08,360 Speaker 1: tell you that, because it really gives me the opportunity 564 00:31:08,400 --> 00:31:11,000 Speaker 1: to offer more features. So these you know, we work 565 00:31:11,120 --> 00:31:12,920 Speaker 1: with O E. M. S and and a lot of 566 00:31:12,920 --> 00:31:15,520 Speaker 1: different people get a lot of great ideas. A lot 567 00:31:15,520 --> 00:31:18,440 Speaker 1: of those ideas actually turn into features and enhancements of 568 00:31:18,480 --> 00:31:20,360 Speaker 1: the product that we can just you know, give to 569 00:31:20,400 --> 00:31:22,720 Speaker 1: our customers. And so you know, your machine gets better 570 00:31:22,760 --> 00:31:25,160 Speaker 1: and better over time. You know, you're never out of date. 571 00:31:25,400 --> 00:31:28,040 Speaker 1: The great one of the great things about the mala 572 00:31:28,120 --> 00:31:30,720 Speaker 1: A C machines is I'll walk up, turn it on, 573 00:31:31,480 --> 00:31:33,920 Speaker 1: and I'll watch it go through an update before I 574 00:31:34,000 --> 00:31:37,200 Speaker 1: use it that day. And it's kind of comforting to 575 00:31:37,320 --> 00:31:40,840 Speaker 1: know that you're working on a problem vehicle in some 576 00:31:40,880 --> 00:31:44,479 Speaker 1: cases and your machine has the absolute up to the 577 00:31:44,560 --> 00:31:49,240 Speaker 1: second latest technology and and and bug fixes. Right, It's 578 00:31:49,280 --> 00:31:51,920 Speaker 1: just it's comforting. It's it's like working with a scan 579 00:31:52,040 --> 00:31:56,520 Speaker 1: tool that that you know is constantly being updated. And 580 00:31:56,880 --> 00:31:59,200 Speaker 1: I haven't seen anybody else in the marketplace do it 581 00:31:59,280 --> 00:32:01,560 Speaker 1: to the level that MALA is doing it, so you 582 00:32:01,560 --> 00:32:04,720 Speaker 1: get you get kudos from me for that, you really do. Hey, listen, Chuck, 583 00:32:04,760 --> 00:32:06,600 Speaker 1: we're gonna we're gonna wind it up because we're gonna 584 00:32:06,640 --> 00:32:09,000 Speaker 1: run out of time. Where before we go, where can 585 00:32:09,040 --> 00:32:11,600 Speaker 1: the listeners get more information? Because obviously we're gonna have 586 00:32:11,640 --> 00:32:13,840 Speaker 1: you back, but in the interim, where can we get 587 00:32:13,880 --> 00:32:16,480 Speaker 1: more information about MALA and a C and all that 588 00:32:16,520 --> 00:32:20,320 Speaker 1: we're gonna deal with this summer and summer's next.

I think they just changed their name recently. 593 00:32:34,280 --> 00:32:38,800 Speaker 1: But um, that's also a good place for training. Um. 594 00:32:38,840 --> 00:32:41,440 Speaker 1: You know, people are gonna want six or nine certification 595 00:32:41,520 --> 00:32:44,920 Speaker 1: certifications to even buy a refrigerant these days, so that's 596 00:32:44,920 --> 00:32:48,000 Speaker 1: a great place for training as well. Good Okay, Well yeah, 597 00:32:48,160 --> 00:32:49,880 Speaker 1: and you're right. You know what we could do three 598 00:32:49,880 --> 00:32:52,240 Speaker 1: more interviews, Truck.

UM, good stuff, really good stuff. 611 00:33:32,320 --> 00:33:35,280 Speaker 1: We use them in the shop. I had a recent call. 612 00:33:35,880 --> 00:33:38,880 Speaker 1: I want to address this. Someone called the shop this 613 00:33:38,960 --> 00:33:42,840 Speaker 1: week and we were talking about she's interested in buying 614 00:33:42,840 --> 00:33:45,040 Speaker 1: a new vehicle and you know, what do I think 615 00:33:45,040 --> 00:33:47,480 Speaker 1: about buying an electric vehicle now? And I said, well, 616 00:33:47,560 --> 00:33:49,920 Speaker 1: you know, I we ran down the list and you 617 00:33:49,920 --> 00:33:52,000 Speaker 1: know the pros and the cons. And I said, but why, 618 00:33:52,080 --> 00:33:54,760 Speaker 1: I said, you've you know, you've been driving this little 619 00:33:54,800 --> 00:33:57,400 Speaker 1: four cylinder Honda Civic for so many years that you know, 620 00:33:57,440 --> 00:33:59,400 Speaker 1: why would you change and get away from that? And 621 00:33:59,760 --> 00:34:02,520 Speaker 1: she she actually drives a stick She's driving an older 622 00:34:02,560 --> 00:34:04,960 Speaker 1: Civic with a stick and she's a stick girl. And 623 00:34:05,040 --> 00:34:08,040 Speaker 1: she you know, she likes to drive stick and I said, 624 00:34:08,080 --> 00:34:09,880 Speaker 1: you know you're gonna get an automatic. I said, aren't 625 00:34:09,880 --> 00:34:12,120 Speaker 1: you gonna miss that the driving style? And she said yeah. 626 00:34:12,160 --> 00:34:14,760 Speaker 1: But she said, you know, why would I buy another 627 00:34:14,800 --> 00:34:18,080 Speaker 1: internal combustion engine a gas engine, because in fifteen years 628 00:34:18,080 --> 00:34:22,759 Speaker 1: everything is gonna be electric. Anyway. I can't imagine being 629 00:34:22,840 --> 00:34:26,080 Speaker 1: ready or trying to buy an electric vehicle now because 630 00:34:26,160 --> 00:34:29,840 Speaker 1: in fifteen years you're worried about getting parts for an 631 00:34:29,880 --> 00:34:33,399 Speaker 1: internal combustion engine. Listen, the electric vehicle isn't gonna last 632 00:34:33,440 --> 00:34:36,319 Speaker 1: five years. You don't think the computer chips and the 633 00:34:36,400 --> 00:34:39,440 Speaker 1: modules and the software that runs that isn't gonna have 634 00:34:39,520 --> 00:34:42,360 Speaker 1: to be updated more than a few times over the 635 00:34:42,360 --> 00:34:45,080 Speaker 1: course of the next fifteen years if it lasted that long. 636 00:34:45,920 --> 00:34:48,360 Speaker 1: From the way the market's talking, I don't think electric 637 00:34:48,400 --> 00:34:50,600 Speaker 1: vehicles are gonna go beyond the five six year mark 638 00:34:50,680 --> 00:34:55,799 Speaker 1: with given current technology and even projected technology. So you know, 639 00:34:56,360 --> 00:34:59,560 Speaker 1: don't count the internal combustion engine out just yet, and 640 00:34:59,680 --> 00:35:01,960 Speaker 1: don't jump the gun. Make sure if you're going to electric, 641 00:35:02,000 --> 00:35:04,839 Speaker 1: you're going for all the right reasons, and make sure 642 00:35:04,880 --> 00:35:07,320 Speaker 1: you're able to deal with the pros and the cons 643 00:35:07,840 --> 00:35:12,400 Speaker 1: of either or so. Just some good long thought processes needed. 644 00:35:12,520 --> 00:35:14,360 Speaker 1: I'm running any in the car. Doctor, thanks for stopping 645 00:35:14,360 --> 00:35:17,440 Speaker 1: by this hour until the next time. Good mechanics aren't expensive, 646 00:35:17,520 --> 00:35:18,840 Speaker 1: they're priceless. Signa
