When I served my time on lorries, mostly Bedfords, we didn’t have a place big enough to work in, so we did it all on the Main Street, this brought back many memories and total respect for these learned gentlemen, I worked in Northern Ireland, it was always raining, and the winters were grim! The garage was a Vauxhall Bedford dealership, the boss was wealthy, the foreman mechanic was a gentleman, in heaven today, I learned a lot from him!
I REMEMBER the feeling in my mid 30's when I had "made it" in life - cos when the car broke down I DIDNT have to crawl under it in the rain on the street and fix it. I called a garage to come and get it - THAT was the biggest luxury imaginable.
Thanks for showing what was broken and replaced. For people like me who are only slightly mechanically inclined, it makes the disassembly and assembly interesting.
@@gingersechelski9117 you don’t need a torque wrench for that kind of work. Loctite, and a 3/4 “ impact gun for the caps, and the yoke, loctite and 1/2” impact for everything else, tighten until they quit turning.

I just love watching these guys. I trained as a heavy plant fitter after leaving the army, I worked for 2 companies & this takes me right back to 1979. These guys are so very professional & so precise & do it with all with minimal equipment. My hat is off to them. Well done all of you.🤜🤛👏👏👏
Not really. They're making a lot of unprofessional mistakes, harmful to the equipment, like spreading the insulation paste, screwing bolts in incorrect order, improperly removing the roller bearings and so on. They show dedication, but skills are far from professional.
@@johno9507 This may have escaped your attention but these guys have very limited resources. If they wash these bearings out with say diesel & after inspection find nothing wrong with them, put them back with a good greasing, the bearing should be good for a limited future but save money & extend the life expectancy of that bearing. You or I would probably not do that, we wouldn't have to, but we are not them.
@@terryalang7283 Actually I was more having a go at what you term as 'professional and precise' and wondering how you came to that conclusion? If you saw this being done in the US or Europe you'd call them 'bodgy backyard mechanics' anything but professional. They didn't even apply Prussian blue to check gear mesh (or use a smear of grease if your broke).
@@johno9507 John O, it obviously works, right! They in my humble opinion have never been formally trained or at least I would assume that. I left the trade in 1979. So given that fact taking it into consideration from my point of view they did a cracking job. Up to your obviously superior capabilities they may not rise.

@@joshuagibson2520 Yeah I don’t want to it either. Many won’t anymore. Finding help is almost impossible. So in the future you’re either going to end up roofing your house yourself, or paying triple what it costs now, unfortunately. That’s some free advice. Start saving your money for maintenance on your home because there is a shortage of good people to do it which is going to drive prices sky-high
In a pinch you can make gear marking compound out of bulk titanium dioxide and some light oil. I've done it and its a useable alternate to the factory compound. Obviously having the factory marking compounds for checking the contact pattern is much easier, but still far better than the grease, which tells you nothing since it adheres to the surfaces. The marking compound does not adhere like a tacky grease does, and provides a good indication of the contact pattern. Even in the absence of tools, its possible to actually determine the correct contact pattern even on used gear sets by moving the pinion depth in .002" increments through the region where the gears are in mesh, while maintaining the correct back-lash after each shim change. This will provide a complete picture of all the possible contact patterns (assuming there are no run-out issues) and allow you to choose one that is close to the specification, or in a used gearset, re-establish the original mesh pattern. Also the bearing preload does not look anywhere close to correct in the finished unit. There needs to be at least some drag. There its spinning freely, which means the gears will be substantially out of mesh under load, and will chip again as the original set did. That setting is quite critical. Again without proper tools, at least in cars, the "cellularmitosis" bearing preload check can be used if your familiar with the type of rear end being worked on. While not precise in any way, shape, or form, it at least tells you if your in the ballpark. It should not just spin like that, even during the mock-up as it wont be representative of the final mesh. Even during the checking phase you want at least _some_ preload on the bearings so the gears are in mesh as they would be once installed. Hypoid differentials are quite touchy when it comes to setup. I suspect the original gearset may have had a similar issue if it was serviced in the past. Edit: 13:50 I can hear all the backlash in the gears, they are quite sloppy, and probably have at least .030", which is far out of typical specifications.
thankyou for the info, i though the bearings sounded abit sloppy as you can hear them slamming when he jigs it back and forth, never thought grease could be an issue but that makes alot of sense as the grease will stick huge gaps together making you think its okay when it isnt

@@dan_6915 but they replaced the broken ring gear and pinion on this truck to complete the repair... that's a job that still gets done today on pickup trucks. They still did a R+R. Also I think I meant to reply to OP

things like this impress me to no end. this is 'in the dirt' REAL mechanics. miracles these guys perform are out of necessity. they are as good as any mechanic you would call "top notch". yeah ... low overhead.
Lucky him, he doesn't need to fight rust, no torch, PB blaster, knuckle busters and broken bolts. That looks like the easiest diff work I have ever seen, bolts don't slide out like that after one winter.
Having watched a few dozen of these videos I notice one regularity - they all specialize in a narrow area of work and thanks to that they achieve good efficiency.
They'll probably just add a bit of sawdust to the oil and it'll sound good as new.....until it snaps the teeth of the next set of gears and they do it all again 🤣
@@grrarg9319 Sawdust to the oil? Jeezoo...is that a thing? A nice space taking up, noise cancelling oil thickener... I never heard of that in my life, but it makes sense
Just what every truck driver dreams of...Having your rear diff rolled around in the dirt, reusing old bearings some guy beat the crap out of with a hammer, and putting the same diff oil back in that came out originally full of metal shavings and dirt? Oh wait, it was filtered by a dirty rag used with the last 7 jobs. The funny thing is that this shop is actually pretty clean compared to others I've seen on YT who work on heavy machinery. It's amazing how long these guys can make equipment last plus they're all working on the ground in sandals!
Western "professional" technician: "You are going to need to buy a new differential and accessories including new pistons and injectors. No sir, this can't be fixed only replaced. It's actually cheaper because we going to charge you less man hours, but actually, not really. Lol. You also need blinker fluid"
Everything done squatting down, amazing how difficult they make it, 3 or 4 guys on it... only slightly destroyed the bearings hammering everything together, truly outstanding it worked at all... good for another hundred miles.
To be fair , that's a very heavy diff plus working on a sand surface, impressive that they have some big air tools though , yes they are rough and crude ,they should have used new bearings but they would have still used a hammer to fit them lol 😂
@@englishbob5106 only the inner pinion bearing suffered by the hammering, with the rest they did not transfer force through the rollers. You can do a fair bit of hammer abuse to the bearing race itself without any negative impact. But I find it weird that they smear grease onto the main which gets bathed in oil, but put absolutely zero lubrication on any of the bearings, which can take quite a bit of time for the splashing oil in the diff housing to get to them...the main bearings did not sound all that nice when he was setting the preload :P I'm however really impressed by the cast iron housing taking all that beating like a champ and not cracking :D
Man I understand your point but sorry. this is how it works in many countries. I live in Brazil for exemple, things are much more expensive here than in the US or other hravly industrialized nations. Because of that we only change bearings when they are with a big slack or crearly damaged. Also sometimes use hammer Becuase don't have ansses to the proper tools. It's hard
@@5fudidao5 I hear ya man, things are tough in the US too, but not changing the bearings will cost you more in the long run. Those sloppy bearings with flat spots will wear those new gears right out again, there is a reason they were damaged in the 1st place.... the cost of new bearings is minor compared to breaking down and doing all that work again no matter where you live...
@@robertw1871 I get your point man it is a smart decision for sure. However sometimes we don't change the bearings becuase of the lack of money to change both the gears and the bearings Hahaha. But your are completely right.
Imagine giving these blokes power tools clean workshop , they are keen good workers and good attitude .they probably get paid jack for their effort I wish them well pity westerners not same work ethics cheers
Who says westerners don't have the same work ethics? Just because these guys are working on a diff in youtube video doesn't mean they have good work ethics. Good work ethics wouldn't allow workers to work on dangerous items with no shoes. Who is it that would give them a clean workshop? Wouldn't that be their own task?

Well for an individual like me who knows nothing about this measurement and that clearance, watching these men work is memories of lying under a 58 Chevy trying to put in the transmission back into position after swapping out the engine.

Ingenuity at work. I was wondering why they assembled the bearings dry until I saw how he did the setup where he spins it fast. Grease would hinder that. Also was surprised not to see any pinion shim. Neat video and nice work 👏

Amazing how they work in coordination with each other to disassemble and reassemble heavy and intricate pieces of equipment and get it correctly put together. Lots of experience and knowhow required to be able to accomplish these tasks. Thank you.
Too bad these guys are woefully ignorant of how to set up a R&P. They didn't check the pinion depth, ring gear carrier bearing preload, or backlash. The slathering of grease on the ring gear showed nothing. That gearset won't last 6 months there.
@@robertdivany1627 that’s hard to believe. I was surprised at the bigger machines that they have. The cost of new parts are significantly lower than the in states. A rear dif part they showed cost $300 new, would be over $1000 in states

Americans would have insisted on a smooth paved shop floor with no grit or sand. The whole assembly would never touch the floor because it would be held by straps on a crane. During assembly backlash, clearances, and alignment would be set with micrometers and plastigage. All components would be coated with assembly lube at each step. The gears would have cost us probably 3 grand at least. And the labor would be 1.5k$. And the truck would have been parked in the shop parking lot for a month as we waited on parts. Probably made and shipped from Pakistan. Or possibly we would have just declared the truck a total loss and bought a new one.
I looked up a real common (and cheap) GM ring and pinion set as there have probably been over 100 million made. They are around $300 US. I would think $239 is pretty cheap for a much larger truck set? Still fascinating to see how well things can be done with minimal equipment.
@@1crazypj I dunno about doing the job well… I can come up with better ways to hammer out bearings and races. I didn’t see them do a very good job keeping dust out of the bearings or even piss on em to rinse the dust off before bolting up the diff…
And this is what men to to provide for their family and keep the trucking business rolling. Not the cleanest shop I have seen but its getting done. Cheers men.
Love these videos. I own a hot rod that I am always toying with and have done some pretty amazing stuff (as least, I thought so) as a shade tree mechanic, but nothing on these guys level. ❤
It is amaizing how they avoid any contamination of the diferentail from the dirt. Not to mention how experienced you have to be to insert a bearing without a press and not cause imature failiure of the components. Hats off
Reused the same bearings that already suffered through the metal debris from the broken pinion...AND mixed up the bearing races and cones...AND didn't do Preload or Backlash? HORRY-SHEET...Lots of luck
@@michaelvangundy226 That is not accurate whatsoever. The grease adheres and smears out all over the face of the teeth, and doesn't provide any other information than that they remembered to install the pinion gear before putting the carrier in. Marking compound is such that it comes away cleanly, and leaves useable witness marks to gauge the contact pattern. As the OP of this comment implies, this thing will probably fail in short order. The biggest issues will be the unknown mesh pattern, lack of any sort of proper preload, and the horrendous backlash. None of these were addressed at any point. It might get the truck down the road for a bit, but it will almost certainly start chipping teeth as the original one did, and probably make the driver go deaf from all the noise its likely to make.
@@mysock351C In the days before every backyard mechanic could afford special tools. We didn't have things like torque wrenches and dial indicators. The method that I learned and used quite a few times was exactly what you saw. You tighten the bearing that forces the two gears together. You make sure it settles then back it off about 3 notches. Tighten the other side to seat the bearing then back it off about 3 notches. Slowly spin it a few revolution to look for any wobble. Put some grease on the teeth and look for an even pressure for seating depth and again for un even travel.
@@michaelvangundy226 You can certainly rebuild them correctly without all the special tooling. Torque wrenches should be used, but even without those they could have gotten pretty close. Close enough for me to at least be comfortable that it would work for a reasonable span of time. As rebuilt, if they are lucky, the new gearset will be close in tolerance to the old one, so reusing the old components will be somewhat close to what's needed. Usually that can be used as more often than not, the housing is 90% of what needs to be compensated for as far as pinion depth goes. As far as runout and other issues go, they cannot be verified by eye, even on a large rear-end like this and a proper dial gauge and inspection of the contact pattern is needed. The grease might work a little bit if your used to seeing it a certain way, but it tells little about how your contact pattern is or any runout issues, and it seems quite sloppy when they installed it. at 13:50 you can hear all the backlash when he turns the coupling. It sounds super loose. That might be ok with spur gears, but without any real indication of preload, its asking for lots of noise and chipped teeth just like we saw at the start of the video. It is true that used bearings will not have quite the same preload, but there's not much indication there's any substantial preload present to keep the gearset in mesh under load. There's a cutscene there, so I could be FOS and they might have got it right in the interim before the camera came back on. I would hope for the owner of the truck that they did. However rebuilding like that relies on the new components being close to what your replacing them with. After chunking a gearset like that, I would want to start from scratch. I've rebuilt rear ends after that kind of failure and they need to be completely stripped and cleaned thoroughly as there are just fist-fulls of metal everywhere. Even if done right, there's probably enough metal floating around in there to doom it to failure again unless somehow they got it clean by hand.
Judging by the sounds this really is a ' Roadside job ' but expertly done. Funny part is the High speed playback makes them sound like an angry lot of Mosquitoes.
I was not aware how people in the region like to decorate their vehicles, the whole cab and frame of this truck looks incredible. Now I know why John Lennon's Rolls Royce was painted in that style. You can certainly put together a differential with way more care, but I give them credit for doing the job in what looks like a few hours without precision equipment.
@@Stroke2Handed He is lucky to have impacts, it sucks they don't have air couplings, he has to unscrew the hose every time he has to switch tools. I mean precise like having at least a torque wrench or a press set up that can handle the bearings. Clearly not an option here, they did the job and hopefully it holds up for him.
@@Stroke2Handed I bet there are vids of the 'correct way to, not just change,(you can buy new, reconditioned ,or used diffs.) but strip and correctly reassemble them.There is something called PR-LOAD....things squeezed hard against each other as well as 'back-lash'--looseness, 'play' between gears.There is fancy equipment and some training involved.
@@Stroke2Handed Ah well, you asked a question about changing diffs. and equipment.I was just pointing out that this was replacing parts IN a diff. and that there is special equipment used to do it so it is a lasting repair and if you had just been asking out of interest ,a video would answer the question I thought you were asking.Looks like you just wanted to make some kind of point. I was a mechanic too and have swapped diffs. but never done the more specialised internal stuff.

One of the main things that gets me over all other is the fact that they do just about everthing while squating, I'm a retired master auto and heavy equipment tech and I can tell you working like that will make you walk strange and feel like an old man real quick.

Instructions: bearing pre load is critical. Guys on dirt floor: more aggressive hammering. This is great. Proves you don't need big fancy shop to get things done when you absolutely need it asap
My preference is to do a job like this properly rather than just "bang it out" to get back on the road quickly. What if that differential fails while driving on some mountain cliff road fifty miles from nowhere? By the way did you notice the condition of that oil draining out of the rear end housing?
Excellent. Gear-Pinion back lash is adjusted with out a dial indicator, kudos to you. Differential mechanism is one of the greatest invention, still more than half of the present population do not know how it works.
All the contamination aside, the pinion shaft bearings are trash after punching them out. I didn't knew this for a long time, but heres why: When driving bearings in you have to apply force on the race which is fitted. On a shaft, inner race, in a seat on the outer race. When you just hammer it in by the outer race while instaling on a shaft you push the outer race against the balls which push against the inner race leaving indentations on all 3 parts which will cause vibrations. When you dont reuse old bearings its irrelevant, but when reusing parts try to apply the pushing force directly on the race you try to push out. Again, bore-outer race, shaft-inner race. Dont use punching pins, i try to use a pipes/sleves, s so the impact goes not in one spot potentially deforming parts.
Absolutely amazing. It takes them a day to do what American mechanics do in a week and then charge us an arm and a leg for it. Love watching you guys work.
In America they use torque wrenches so the bolts don't loosen up and fall out. In America, they know how to set the pinion depth, diff bearing preload, ring gear backlash so the R&P lasts more than a couple of months. In other words, that repair in America will last a million miles at 70mph. The job done in this video won't last 6 months in that truck that might see 40-50mph tops.
So they have to overload the trucks to get the job, then drive a dangerous vehicle to make money. After that they have to pay for repairs. Not an ideal system.
Even in Thailand which is one of the underdeveloped countries as well ,The first thing that the teacher teaches is that the work area must be clean and free from sand and dust. I saw them put their oil-soaked gears on the gravel and couldn't figure out what was going to get in there.

@@bigcheese781 I know right, I don't even remove bearings so aggressively to throw them away, and they bloody reused theirs after banging ferociously on both the races and cages with a bigass hammer. Tragic workmanship, botched repair.
Inner pinion bearing should be good for at least 500 miles after its been pounded in like that. It’s weird that they do all the hard work and yet they don’t have a simple home made press to fit the bearings. They could make one with some steel box section and a bottle jack in a couple of hours. Also, that sounded nasty when the preload was being set!
@@numberpirate that's some fake news that you didn't bother to fact check because its confirmation bias for your sick mind. No wonder you can't afford something better than a damn prelude
Back before I had all the tools I do now, I installed bearings like that and... maybe I just got lucky but it was never a problem. Those bearings and races are pretty tough. But yeah... that bearing preload and backlash didn't sound good.
I'm very confident that this diff will be just fine 50,000 miles from now, if not 100,000. If this unit went bad within 1000 miles from now then there would be very serious consequences for the builder. This isn't America where you would take them to courrt and file a complaint with the BBB. Here this repair cost the owner a LOT of money (to him) and this truck is his living. He will NOT tolerate this failing prematurely. Its obvious these guys know exactly what they are doing and you have no idea what they did and didn't check and how they check it. The video is 14 minutes long, do you think they actually did this job in 14 minutes? These guys do this shit all day, every day and they know how to do it. They checked the pattern and with adjusters they are probably practiced enough to know backlash just by jiggling it. Do this stuff enough and inch-pounds torque required for preload can be felt. How many diffs this big have YOU set-up?
Guys, reusing old bearings that have been smacked apart and smacked back on…just… yikes. Use heat and cold next time. You also need feeler gauges to set the clearances corrected. Over torque and you massively increase friction.
despite all the imperfections in the assembly, this truck will again make a lot of miles. if not, the shop would have gone bankrupt long ago. the owners of the trucks aren't idiots......
In those countries all shops are the same. Basically the owner is now heading to another shop to change bearings. I live in one of those countries, even official Chevrolet dealer could not assemble correctly wheel hub, so it took me to buy a lot of tools and search internet for service manual.
That they are old(er) simple basic trucks helps too, no tiptronics, ABS, or all that kind of snitzsnatz making that alot easier to repair in the field, old sovjet doctrine, it has to be repairable with a hammer, a wrench and a farmboy, try to keep a modern western truck with all its gadgets running there, our trucks would give up after just one haul there.

I REMEMBER the feeling in my mid 30's when I had "made it" in life - cos when the car broke down I DIDNT have to crawl under it in the rain on the street and fix it.
I called a garage to come and get it - THAT was the biggest luxury imaginable.

Not really. They're making a lot of unprofessional mistakes, harmful to the equipment, like spreading the insulation paste, screwing bolts in incorrect order, improperly removing the roller bearings and so on. They show dedication, but skills are far from professional.
Professional...Are you kidding??
They're reusing the old bearings after all those pieces of metal circulated through the oil.
@@johno9507 This may have escaped your attention but these guys have very limited resources. If they wash these bearings out with say diesel & after inspection find nothing wrong with them, put them back with a good greasing, the bearing should be good for a limited future but save money & extend the life expectancy of that bearing. You or I would probably not do that, we wouldn't have to, but we are not them.

Actually I was more having a go at what you term as 'professional and precise' and wondering how you came to that conclusion?

In a pinch you can make gear marking compound out of bulk titanium dioxide and some light oil. I've done it and its a useable alternate to the factory compound. Obviously having the factory marking compounds for checking the contact pattern is much easier, but still far better than the grease, which tells you nothing since it adheres to the surfaces. The marking compound does not adhere like a tacky grease does, and provides a good indication of the contact pattern. Even in the absence of tools, its possible to actually determine the correct contact pattern even on used gear sets by moving the pinion depth in .002" increments through the region where the gears are in mesh, while maintaining the correct back-lash after each shim change. This will provide a complete picture of all the possible contact patterns (assuming there are no run-out issues) and allow you to choose one that is close to the specification, or in a used gearset, re-establish the original mesh pattern. Also the bearing preload does not look anywhere close to correct in the finished unit. There needs to be at least some drag. There its spinning freely, which means the gears will be substantially out of mesh under load, and will chip again as the original set did. That setting is quite critical. Again without proper tools, at least in cars, the "cellularmitosis" bearing preload check can be used if your familiar with the type of rear end being worked on. While not precise in any way, shape, or form, it at least tells you if your in the ballpark. It should not just spin like that, even during the mock-up as it wont be representative of the final mesh. Even during the checking phase you want at least _some_ preload on the bearings so the gears are in mesh as they would be once installed. Hypoid differentials are quite touchy when it comes to setup. I suspect the original gearset may have had a similar issue if it was serviced in the past. Edit: 13:50 I can hear all the backlash in the gears, they are quite sloppy, and probably have at least .030", which is far out of typical specifications.

Just what every truck driver dreams of...Having your rear diff rolled around in the dirt, reusing old bearings some guy beat the crap out of with a hammer, and putting the same diff oil back in that came out originally full of metal shavings and dirt? Oh wait, it was filtered by a dirty rag used with the last 7 jobs. The funny thing is that this shop is actually pretty clean compared to others I've seen on YT who work on heavy machinery. It's amazing how long these guys can make equipment last plus they're all working on the ground in sandals!
Western "professional" technician: "You are going to need to buy a new differential and accessories including new pistons and injectors. No sir, this can't be fixed only replaced. It's actually cheaper because we going to charge you less man hours, but actually, not really. Lol. You also need blinker fluid"
Everything done squatting down, amazing how difficult they make it, 3 or 4 guys on it... only slightly destroyed the bearings hammering everything together, truly outstanding it worked at all... good for another hundred miles.
To be fair , that's a very heavy diff plus working on a sand surface, impressive that they have some big air tools though , yes they are rough and crude ,they should have used new bearings but they would have still used a hammer to fit them lol 😂
@@englishbob5106 only the inner pinion bearing suffered by the hammering, with the rest they did not transfer force through the rollers. You can do a fair bit of hammer abuse to the bearing race itself without any negative impact. But I find it weird that they smear grease onto the main which gets bathed in oil, but put absolutely zero lubrication on any of the bearings, which can take quite a bit of time for the splashing oil in the diff housing to get to them...the main bearings did not sound all that nice when he was setting the preload :P
I'm however really impressed by the cast iron housing taking all that beating like a champ and not cracking :D
Man I understand your point but sorry. this is how it works in many countries. I live in Brazil for exemple, things are much more expensive here than in the US or other hravly industrialized nations. Because of that we only change bearings when they are with a big slack or crearly damaged. Also sometimes use hammer Becuase don't have ansses to the proper tools. It's hard
@@5fudidao5 I hear ya man, things are tough in the US too, but not changing the bearings will cost you more in the long run. Those sloppy bearings with flat spots will wear those new gears right out again, there is a reason they were damaged in the 1st place.... the cost of new bearings is minor compared to breaking down and doing all that work again no matter where you live...

Americans would have insisted on a smooth paved shop floor with no grit or sand. The whole assembly would never touch the floor because it would be held by straps on a crane. During assembly backlash, clearances, and alignment would be set with micrometers and plastigage. All components would be coated with assembly lube at each step. The gears would have cost us probably 3 grand at least. And the labor would be 1.5k$. And the truck would have been parked in the shop parking lot for a month as we waited on parts. Probably made and shipped from Pakistan. Or possibly we would have just declared the truck a total loss and bought a new one.
Well, such an assembly is not a fact that it will work for a long time. Commercial vehicles have never been cheap to repair.
@@scottsdale4899 Yea those bearings just had their lifespan severely shortened.
I looked up a real common (and cheap) GM ring and pinion set as there have probably been over 100 million made. They are around $300 US. I would think $239 is pretty cheap for a much larger truck set? Still fascinating to see how well things can be done with minimal equipment.

They set the backlash by grease and looking at the pattern. Tight and back off a couple of notches. That's ok.
@@michaelvangundy226 That is not accurate whatsoever. The grease adheres and smears out all over the face of the teeth, and doesn't provide any other information than that they remembered to install the pinion gear before putting the carrier in. Marking compound is such that it comes away cleanly, and leaves useable witness marks to gauge the contact pattern. As the OP of this comment implies, this thing will probably fail in short order. The biggest issues will be the unknown mesh pattern, lack of any sort of proper preload, and the horrendous backlash. None of these were addressed at any point. It might get the truck down the road for a bit, but it will almost certainly start chipping teeth as the original one did, and probably make the driver go deaf from all the noise its likely to make.
@@mysock351C
In the days before every backyard mechanic could afford special tools. We didn't have things like torque wrenches and dial indicators. The method that I learned and used quite a few times was exactly what you saw.
You tighten the bearing that forces the two gears together. You make sure it settles then back it off about 3 notches. Tighten the other side to seat the bearing then back it off about 3 notches. Slowly spin it a few revolution to look for any wobble. Put some grease on the teeth and look for an even pressure for seating depth and again for un even travel.
@@michaelvangundy226 You can certainly rebuild them correctly without all the special tooling. Torque wrenches should be used, but even without those they could have gotten pretty close. Close enough for me to at least be comfortable that it would work for a reasonable span of time. As rebuilt, if they are lucky, the new gearset will be close in tolerance to the old one, so reusing the old components will be somewhat close to what's needed. Usually that can be used as more often than not, the housing is 90% of what needs to be compensated for as far as pinion depth goes. As far as runout and other issues go, they cannot be verified by eye, even on a large rear-end like this and a proper dial gauge and inspection of the contact pattern is needed. The grease might work a little bit if your used to seeing it a certain way, but it tells little about how your contact pattern is or any runout issues, and it seems quite sloppy when they installed it. at 13:50 you can hear all the backlash when he turns the coupling. It sounds super loose. That might be ok with spur gears, but without any real indication of preload, its asking for lots of noise and chipped teeth just like we saw at the start of the video. It is true that used bearings will not have quite the same preload, but there's not much indication there's any substantial preload present to keep the gearset in mesh under load. There's a cutscene there, so I could be FOS and they might have got it right in the interim before the camera came back on. I would hope for the owner of the truck that they did. However rebuilding like that relies on the new components being close to what your replacing them with. After chunking a gearset like that, I would want to start from scratch. I've rebuilt rear ends after that kind of failure and they need to be completely stripped and cleaned thoroughly as there are just fist-fulls of metal everywhere. Even if done right, there's probably enough metal floating around in there to doom it to failure again unless somehow they got it clean by hand.
I never saw a pinion seal installed. I wonder if they caught that when they filled it up, or a few miles up in a mountain pass?

Єто точно, уровень ремонта всегда один - дилетантский.
One of the main things that gets me over all other is the fact that they do just about everthing while squating, I'm a retired master auto and heavy equipment tech and I can tell you working like that will make you walk strange and feel like an old man real quick.
I have nothing but respect for this folks!!!
I found that really enjoyable and relaxing to watch. These guys get sh*t done !!!! OH&S might like a chat, haha.
I love the way they always have a cleaning rag in their hands, and they always clean things...brilliant...
These guys seriously do amazing work with very little bravo!
The gentlemen working in quite a precise sequence, deserves a large respect for their "know hows", in all that they perform; such great perfomances! God bless each one of them! And I know He does too! Aleluia Amene? Aloha
Instructions: bearing pre load is critical.
Guys on dirt floor: more aggressive hammering.
This is great. Proves you don't need big fancy shop to get things done when you absolutely need it asap
He also tossed his slip yoke in the sand too. Wtf
Lmfao, thats how you keep ‘em coming buddy ;), how you think they can make so many CZcams vids
set gear backlash by ear lol and did you see the contact pattern? Amazing. i cant do that well with a dial indicator lol
Our mechanic would take 3 days to do this with all the fancy tools
My preference is to do a job like this properly rather than just "bang it out" to get back on the road quickly. What if that differential fails while driving on some mountain cliff road fifty miles from nowhere? By the way did you notice the condition of that oil draining out of the rear end housing?
It's amazing what can be accomplished with rudimentary equipment. Not the right way to do preload, backlash or pinion depth, however.
Hate to think the noise from an axle that hasn't had correct preload & pinion mesh set
Ya , But they got it done !
Excellent. Gear-Pinion back lash is adjusted with out a dial indicator, kudos to you. Differential mechanism is one of the greatest invention, still more than half of the present population do not know how it works.
Good to see that they work in other things not just calling people about their social’s being suspended.
And air duct cleaning 😄
Or the Warranty on the five hundred dollar F350 I’ve been rocking for 4 years
Я один думал что они сейчас электродом насрут новые зубья, а потом болгаркой почухают в нужный профиль?
Не один...
Тоже ожидал возрождения пары из картона)
не один.
не говори вообще охренели, тоже ждал чего угодно кроме нового)
I love watching these videos. They are very efficient in their craft.
I love watching these guys work.
All the contamination aside, the pinion shaft bearings are trash after punching them out.
I didn't knew this for a long time, but heres why:
When driving bearings in you have to apply force on the race which is fitted.
On a shaft, inner race, in a seat on the outer race.
When you just hammer it in by the outer race while instaling on a shaft you push the outer race against the balls which push against the inner race leaving indentations on all 3 parts
which will cause vibrations.
When you dont reuse old bearings its irrelevant, but when reusing parts try to apply the pushing force directly on the race you try to push out.
Again, bore-outer race, shaft-inner race.
Dont use punching pins, i try to use a pipes/sleves, s so the impact goes not in one spot potentially deforming parts.
“This truck is loaded”, yeah most likely overloaded, way overloaded.
They usually are lol
If they took all that sh1t off the front end the load capacity would be doubled
Hard work nice job bro
Very satisfying watching these craftsmen at work. 👍👍
That's an expensive fix, over there. I love how quick they got this done. Take me a day to pull the rear, them 30 min...
These guys are skinny and strong all muscle. Americans all have a pot belly me too we work slow.
@@Mike-01234 Sure... They do not even have mechanic hands. Small.
Obrigado comentaristas do mundo inteiro, dei várias risadas!
Hate to see bearings and shafts hit with hammers 😳 Doing what they can for a price i suppose.
Heh - they mounting the same old bearings with hammer. Real engineering here :)
"it's fine as long as the truck's moving again" a concept you can find in any individual repair shop in any developing nations =_=
I'm wondering if that pan of oil was re-used to (yikes!). Do what you can with what you have I suppose.
Nope, can make a bearing puller from some scrap flat bar and threaded rod, no excuses for that gimpy haha.
Those bearing probably have a million miles on them
Меня больше уделяет как они работают на земле с мазутом в своих светлых халатах
Absolutely amazing. It takes them a day to do what American mechanics do in a week and then charge us an arm and a leg for it. Love watching you guys work.
You get what you pay for
In America they use torque wrenches so the bolts don't loosen up and fall out. In America, they know how to set the pinion depth, diff bearing preload, ring gear backlash so the R&P lasts more than a couple of months. In other words, that repair in America will last a million miles at 70mph. The job done in this video won't last 6 months in that truck that might see 40-50mph tops.
So they have to overload the trucks to get the job, then drive a dangerous vehicle to make money.
After that they have to pay for repairs.
Not an ideal system.
Even in Thailand which is one of the underdeveloped countries as well ,The first thing that the teacher teaches is that the work area must be clean and free from sand and dust.
I saw them put their oil-soaked gears on the gravel and couldn't figure out what was going to get in there.
i would not call Thailand an underdeveloped country ..much more manufacturing than here in the UK and fewer potholes in the roads ..and my mate broadband was faster than mine
you do realize that the ring and pinion were replaced with a new ring and pinion that were not rolled around in the sand?
@@jamesradcliffe3985 : Good on you, take your broken diff to them then and tell me how long it lasted. 🤣🤣👍
Me, personally will not (for the exact reason David states).
@@77appyi Also watch the video on the long tailed boats. The engine building and supercharging they do is amazing. One even shows the super cars they build as well.
@@bigcheese781 I know right, I don't even remove bearings so aggressively to throw them away, and they bloody reused theirs after banging ferociously on both the races and cages with a bigass hammer. Tragic workmanship, botched repair.
I'm sure the one that failed was assembled exactly the same way this one was. Stay tuned for the next replacement.
Can't last forever, it's normal After 800 000 KM on the Roads !!
When doing rear ends it’s imperative to use blue dye and set the lash properly otherwise you’re just gonna repeat the same problem
You are 100% Right
I just eye ball it, works out the same
Lovely work lads Greetings from Ireland.
Very good job! I miss doing this kind of work sometimes, but then I come to my senses :)
i dont miss that shit at all lol my back axhes everyday from that heavy shit
@@aegismule13 I know, right? My body is ruined from 35 years of it.
Inner pinion bearing should be good for at least 500 miles after its been pounded in like that. It’s weird that they do all the hard work and yet they don’t have a simple home made press to fit the bearings. They could make one with some steel box section and a bottle jack in a couple of hours. Also, that sounded nasty when the preload was being set!
Everything in pakistan requires a hammer and a bigger hammer!
What preload? Everything seemed to spin much too freely, plus the crownwheel was out of mesh?
@@numberpirate that's some fake news that you didn't bother to fact check because its confirmation bias for your sick mind. No wonder you can't afford something better than a damn prelude
Back before I had all the tools I do now, I installed bearings like that and... maybe I just got lucky but it was never a problem. Those bearings and races are pretty tough.
But yeah... that bearing preload and backlash didn't sound good.
I'm very confident that this diff will be just fine 50,000 miles from now, if not 100,000. If this unit went bad within 1000 miles from now then there would be very serious consequences for the builder. This isn't America where you would take them to courrt and file a complaint with the BBB. Here this repair cost the owner a LOT of money (to him) and this truck is his living. He will NOT tolerate this failing prematurely. Its obvious these guys know exactly what they are doing and you have no idea what they did and didn't check and how they check it. The video is 14 minutes long, do you think they actually did this job in 14 minutes? These guys do this shit all day, every day and they know how to do it. They checked the pattern and with adjusters they are probably practiced enough to know backlash just by jiggling it. Do this stuff enough and inch-pounds torque required for preload can be felt. How many diffs this big have YOU set-up?
I dont know anything about truck repairs, but these guys look like they really know what they're doing.
Guys, reusing old bearings that have been smacked apart and smacked back on…just… yikes.
Use heat and cold next time.
You also need feeler gauges to set the clearances corrected. Over torque and you massively increase friction.
A pin doesnt just break without a reason, and its most likely the bearings :D
Or use a proper press/puller.
It's a good temp fix. Truck is moving, I think.
Yea that will not be on the roads for a long time, bearings are not so expensive nowdays anyway. at 11:55 you can hear the bad bearings
like to show this to the local snap-on / mac reps.
despite all the imperfections in the assembly, this truck will again make a lot of miles.
if not, the shop would have gone bankrupt long ago.
the owners of the trucks aren't idiots......
In those countries all shops are the same. Basically the owner is now heading to another shop to change bearings. I live in one of those countries, even official Chevrolet dealer could not assemble correctly wheel hub, so it took me to buy a lot of tools and search internet for service manual.
@@donalexey in those countries?
a chevrolet dealer anywhere in the world cannot assembly anything ...
That they are old(er) simple basic trucks helps too, no tiptronics, ABS, or all that kind of snitzsnatz making that alot easier to repair in the field, old sovjet doctrine, it has to be repairable with a hammer, a wrench and a farmboy, try to keep a modern western truck with all its gadgets running there, our trucks would give up after just one haul there.
@@arranchace1306 it would give up only because either there's no dealer who can provide spare parts Or the spare parts are very much expensive and can't be affordable by these guys.
I get a kick out of how impressed people are with this. They are professionals so ofcourse they can fix a broken truck.
A kick isv very well deserved for these hardworking mice
These guys are legends, it takes a lot of skill to set up that new alignment
Ну надо же! Пневматические гайковерты! Прогресс однако!
И тележка про то находка. Уже не на земле.
So fast an the speed they talk is astounding
All I hear is squeals
It's called urdu
What a good street Humam resource.I am so happy to watch this video though I am not an engineer. Very good job.
Great respect to these men. Seeing them do all this in sandals and no protective gear is mind blowing. LOL
Хм, в одном из прошлых роликов (или похожих), зубья восстанавливали наваркой, что дикий колхоз, а тут новые детали. Вопрос - куда же пошла та деталь??!! А так, норм ремонт, разобрали - собрали.
Думаю они заварили шестерню по приколу, ради контента!😅
Смотришь как фантастику
Есть методики востоновления зубьев. Электроды не тока ок46. И уони 5412
Это тот же грузовик успел до ехать до следующей мастерской
Ну да. На холодную то подшипники с посадок молотком долбить - норм ремонт :)
I take it they replace these as often as tires.
These guys are Good Techs.
They fix junk with almost nothing and Whirled continues to motor on
В принципе все сделано по уму. Детали отмыты, отдефектованы. Пара заменена и отрегулирована. Пятно контакта выставлено. Даже картонка при сборке подложена) У нас такая работа рублей 100 стоит. Интересно сколько они берут.
Ну я думаю не больше косаря.
А вылет морковки?
