12:20 this pinion to ring gear backlash/clearance meter is very precise it uses HEB tech. ( Hands ,Ears, Brain ). I love how you guys do amazing things with nothing, i saw you even made the tool to rotate the adjustment rings with an old adjustment ring, brilliant. When i watch your videos i realize how much people around me are spoiled with fancy tools and workers conventions.. You guys are outside wearing nothing but sandals and basic tools and you still do miracles! It humbles me deeply when i see your level of perseverance in the face of adversity. Your courage is exemplary! Hats off to all of you.
I thought using the grease to verify proper adjustments was golden, an absolute master-stroke. Reminded me of times in my uncle's shop. He fixed dirt-moving gear.

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.
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.
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.

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?

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.
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…
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
That will not last long the contact patch is way off. They would be great mechanics with just a little proper training....A+ for effort....D- for execution of the technical bits. That being said I would hire them in a heart beat and give them some proper skills!
The pinion depth was done by "feel" as long as it not too tight should last awhile.It will probably get noisy but function.I was told that that type of damage comes from backing up and hitting something hard.Thats devastating to ring and pinion.
@@Z4Zulfiqar You misunderstood what I was saying. Not a gasket, but the actual lip seal for the pinion, they forgot to install it before the yoke and dust shield. Silicone would not work there.
It's not impressive it's amazing that anthing works there. Dirty, beating on everything with a hammer. Beating bearings off and reused and beaten back on. It's amazing that anthing works.
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
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?
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.
@@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.
DRRRR: 1) Propshaft NOT marked for PHASING match. 2) Strip-down process of wrecked differential insanely filthy, but otherwise irrelevant. 3) Wash-down process was spirited, but useless in a pan that re-introduces FILTH ito the assembly. No air-hose blow-out! 4) THE WORST: Re-installation of swarf-exposed (DAMAGED) bearings onto the pinion, 5) No measuring of pinion height (SHIMS??), no run-out check, no pre-load applied. No torque settings applied 6) Land/Heel engagement pattern checked incorrectly, backlash checked by hand (rather than by micrometer). This differential will FAIL AGAIN within 5000 km, parts quality is NOT THE ISSUE: The repair procedure (for want of a better expression) is insufficient. (for want of a better expression) . What a JOKE.
For some reason YT keeps throwing these videos at me. I mean, who really wants to watch these greasy rubes fix things by hitting them on the ground!? Also, we should pity the people gushing in the comments, they encourage ignorance.
baclash to set with dial guage to manufactures spec etched on crown wheel tooth contact use red and blue tooth contact paint and preload before turning
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?
Reusing metal contaminated bearings, spinning dry bearings, not setting pinion depth or ring gear backlash. Not to mention the axles and rear housing are still coated with metal contaminated gear oil. Makes me wonder how long the new ring and pinion will last.

Do you think this has been driven 6 million miles? if it has then I think its safe to say those Pakistani mechanics know their shit.
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.
Bro these mechanics are not educated ,they dont know what is back lash ,pinion depth,preload on pinion bearings ,ring gear carrier bearings .They just replace the items by copying their previous fitted fashion.

I’ve yet to see clean oil come out of a differential case. I would like to believe that occasionally changing oil goes a long way to prevent broken gears ? I dunno.
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.

I applaud them for working with what they have, but if they have access to a relatively unique tool such as C-clip removal pliers surely they can get a bearing/gear puller, that tool is literally just cast and threaded hunks of metal prongs that are meant to be used in situations like this, not special by any means, and easy to use.

Fair enough, I understand that their trucks get seriously overloaded and get driven over rotten pot-holed roads, but even so, at least some of the failures should not have occurred - not in the way they occurred anyway. What had probably happened is that trucks completed a reasonable service life and when something just got too worn out, these sledge hammer chaps repaired it so that it could be driven again, but due to the bad repair practices, it failed again - so they repaired it again.... And again ....
@@keithammleter3824 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?
@@jamesradcliffe3985 Oh, I wouldn't be surprised if that diff lasts 1,000 miles. Maybe 5,000 miles. But definitely not 100,000. And it should last 300,000. And after 300,000, fail by wearing down, not catastrophically eg broken teeth. This diff failed catastrophically probably because it got contaminated oil or it was repaired after wear out by these same turkeys, albeit maybe triggered by overloading and a pothole. Yes, these guys are not stupid, and they do know stuff. They didn't check meshing the way a competent Western truck mechanic would do it, but they used a grease method that works. But if you have worked in a mechanical repair business (and I have - I was the engineer - that's the man in charge of all work - in a large dealer for a large engine manufacturer) you see many things in these videos that would cause instant sacking in a Western country. Eg hitting bearings. Others on this video and other Pakistani truck videos have made the same comments, but I'll make a couple of them again for you - the first thing you learn at trade school and from your boss is cleanliness is absolutely essential. And these Paki guys work in the dirt. They let all fluids drain on the ground. If they captured fluids and kept a clean concrete floor, they could use their own gantry and not have to hire a mobile crane every day to lift things - that's what they do, watch other videos and see. A lot of what these guys do just doesn't make any sense. They are self taught. Pakistan is a lot like India - much of their culture comes from India, where sloppy work and ripping-off is the norm and nobody seems to understand that it need not be so. A place where sloppy work doesn't get them in court, because they don't have a suing culture and the competition is just as bad.
@@keithammleter3824 I saw them emptying fluids into a big pan. I saw them using cardboard under their parts after they were cleaned, yes, they didn't use a $600.00 snap-on diff cradle on a 400.00 jack to move the shit around, they're not stupid. Funny you mention sloppy work, I bet this truck was imported between 1930 and 1970 from somewhere in Europe, and just like all those other trucks you see, are still getting the snot beat out of them daily, and still running. Funny, but I look on our roads and all I see are top-of-the-line kenworths/ freightliners etc. that are no more than 10 years old.........
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.
only thing bad in this video is fake thumbnail of the giant gear

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
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?
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!

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.

Re using bearings on new gears is bad, but especially so after running all the metal from the first failure though them will be the kiss of death.
Agreed, not worth re-using most bearings as they are cheap parts compared to the rest.

@@kinasc1575 I was wondering if they needed to be greased...
Not necessarily..if they had kept the races and cones together then it would have been ok..but they mixed them up....
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.

6:35 "моем до состояния, привет пиздец как-чисто"
I always say, "When in doubt, get a bigger hammer."
It's cool to see it in actual use.
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
It's not impressive it's amazing that anthing works there. Dirty, beating on everything with a hammer. Beating bearings off and reused and beaten back on. It's amazing that anthing works.
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.

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?
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.
DRRRR: 1) Propshaft NOT marked for PHASING match. 2) Strip-down process of wrecked differential insanely filthy, but otherwise irrelevant. 3) Wash-down process was spirited, but useless in a pan that re-introduces FILTH ito the assembly. No air-hose blow-out! 4) THE WORST: Re-installation of swarf-exposed (DAMAGED) bearings onto the pinion, 5) No measuring of pinion height (SHIMS??), no run-out check, no pre-load applied. No torque settings applied 6) Land/Heel engagement pattern checked incorrectly, backlash checked by hand (rather than by micrometer).
This differential will FAIL AGAIN within 5000 km, parts quality is NOT THE ISSUE: The repair procedure (for want of a better expression) is insufficient. (for want of a better expression) . What a JOKE.
For some reason YT keeps throwing these videos at me.
I mean, who really wants to watch these greasy rubes fix things by hitting them on the ground!?
Also, we should pity the people gushing in the comments, they encourage ignorance.
I love how they checked end play by sound. That's freaking awesome.
All you really need
And then we roll it around on the ground to see how much dirt we can get into the bearings!
The dirt will act as an abrasive media, helping the bearings break-in......
They not roll on the ground and they roll on the paper can you see that or not
Plus the washing of the parts in the dirty metal shaving water… just spreading the shavings around
baclash to set with dial guage to manufactures spec etched on crown wheel tooth contact use red and blue tooth contact paint and preload before turning
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 TH-cam 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?
Savage Mode Mechanics! 🔥 🔥
Incredible they do all this work in their pajamas
Reusing metal contaminated bearings, spinning dry bearings, not setting pinion depth or ring gear backlash. Not to mention the axles and rear housing are still coated with metal contaminated gear oil. Makes me wonder how long the new ring and pinion will last.

@@agt155 Might be a different story for new bearings. The gears were probably made in China.
I'm very surprised that they had a one inch air impact wrench! And they compressor to swing it!
These guys need to invest in a 1/2 " and a 3/4 " torque wrenches those bearings would last a lot longer if they had the proper torq on them
And how do you pretend they’re going to keep them coming?

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.
There was no preload on them pinion bearing or carrier bearings lol,but there getting it done,it will work but it's gonna eat them bearings up.
Bro these mechanics are not educated ,they dont know what is back lash ,pinion depth,preload on pinion bearings ,ring gear carrier bearings .They just replace the items by copying their previous fitted fashion. In whole pakistan such kind of mechanics only cause damage to these expensive vehicles by fitting differentials like this.Even engines cylinder head bolts are fitted without sequence without torque wrenches.Very disappointing.😭😭😭
And it appears no oil either.
Keep in mind these are poor people doing repairs without the benefit of a professional garage . All things considered they did a great job . I'm sure their repair job will last Equally as long as repairs done at a TRUCK DEALERSHIP .
What do you mean? They’ve got air guns? They do have a shop. are just used to Mother Nature’s air conditioner.
You say poor I say normal
These first 2 comments are proof that there are Jack@$$e$ on TH-cam are always looking for a excuse to argue . To clarify things for these Jack@$$e$ on the TH-cam comments section these mechanics are to poor to afford to buy all of the same tools that the OEM TRUCK DEALERSHIPS use and they also can't afford to build a OEM Truck Dealership style / approved garage to do their repair work in . They use aftermarket cheap tools and work in a makeshift garage & sometimes outside . But they still DO GREAT repair work for their customers despite not have OEM TRUCK DEALERSHIP approved garage and tools .
@@brieannateylar5810 oh boy.
OK you go ahead and drive a vehicle whose bearings have been pounded off with steel hammers, on their outer races.
I'll pass.
They're doing the best job they can with the tools they have. Doesn't mean it's a good job.
@@briandg25ify next time you go out on the Hwy look at the vehicles around you . I can guarantee you that at least 1/4 of those vehicles were fixed by a BACKYARD MECHANIC using the same techniques the guys are using . I can bet that their repair work will last Equally as long as a dealership . In fact I bet you've rode on a vehicle worked on by a BACKYARD MECHANIC before and just don't know it .
Always rubbed liquid lube on bearings when setting rear axles. Premature bearing failure may happen. Good job successfully completing job though.
I’ve yet to see clean oil come out of a differential case.
I would like to believe that occasionally changing oil goes a long way to prevent broken gears ?
I dunno.
Excellent! Work 🚛 smart.
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.

A Brother advise to my brothers in Pakistan, please follow strictly to make a good , safe ,and long lasting job.
# 1 after disassembly, degrease parts, look for abnormal wear on gear teeth for spalling and chipped off material on gear teeth and replace as required. replace all bolts, washers, packing and retaining rings with new parts. when ready , to re- assemble, please move all parts to a clean area ( no dust please ) and start assembling according to OEM REQUIREMENTS, make sure you have all the parts required to assemble, also you will need torque wrench, clean oil or grease, locking nut and washers are new take picture where required, you will need dial indicator gage or stand to check for GEAR BACKLASH/ OR CLEARANCE USE SHIMS WHERE REQUIRED,BEFORE PUTTING AT BACK ON THE TRUCK, a quick look for ( FOD DAMAGDE) no tool of any kind in side. By the grace of God we can put it back, please pray for me and for all the ummah that is suffering from miscellanies calamities. ALLAHA HAFIZ from my beautiful city of JHELUM.

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
I applaud them for working with what they have, but if they have access to a relatively unique tool such as C-clip removal pliers surely they can get a bearing/gear puller, that tool is literally just cast and threaded hunks of metal prongs that are meant to be used in situations like this, not special by any means, and easy to use. Hammering the bearings with screwdriver is no bueno.
You can weld it yourself if you can't buy it. But looks they prefer hammering it.
Did you notice they never showed installing the front shaft seal...
@@iqoverlord yah i was about to say that
@@iqoverlord I'd bet it was pounded on. This is where formal training has its uses. These guys are definitely crafty, and can fix things, but the lack of some basic important info is evident.
@@iqoverlord i think they did when one of them was doing a pinion bearing the other used a punch to seat the seal by banging it in a bunch of places to seat it.
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 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.
What precision equipment does one require to to change the rear diff? He's lucky to have had an air impact.
@@Stroke-it-2-Handed 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.
@@Stroke-it-2-Handed 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.
@@ianrutherford878 I don't need to watch videos of people working on diffs. I'm well into my 40's and have been working on cars myself since the '90s.
@@Stroke-it-2-Handed 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.
Amazing work guys, just love it!!

hello brothers. do you wash parts in gasoline?
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 👏

Great job! Well done! I just didn't see if you poured new oil or the old one? I am curious :)
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!

What had probably happened is that trucks completed a reasonable service life and when something just got too worn out, these sledge hammer chaps repaired it so that it could be driven again, but due to the bad repair practices, it failed again - so they repaired it again....

Yes, these guys are not stupid, and they do know stuff. They didn't check meshing the way a competent Western truck mechanic would do it, but they used a grease method that works. But if you have worked in a mechanical repair business (and I have - I was the engineer - that's the man in charge of all work - in a large dealer for a large engine manufacturer) you see many things in these videos that would cause instant sacking in a Western country. Eg hitting bearings. Others on this video and other Pakistani truck videos have made the same comments, but I'll make a couple of them again for you - the first thing you learn at trade school and from your boss is cleanliness is absolutely essential. And these Paki guys work in the dirt. They let all fluids drain on the ground. If they captured fluids and kept a clean concrete floor, they could use their own gantry and not have to hire a mobile crane every day to lift things - that's what they do, watch other videos and see.
A lot of what these guys do just doesn't make any sense. They are self taught.
Pakistan is a lot like India - much of their culture comes from India, where sloppy work and ripping-off is the norm and nobody seems to understand that it need not be so. A place where sloppy work doesn't get them in court, because they don't have a suing culture and the competition is just as bad.
@@keithammleter3824 I saw them emptying fluids into a big pan. I saw them using cardboard under their parts after they were cleaned, yes, they didn't use a $600.00 snap-on diff cradle on a 400.00 jack to move the shit around, they're not stupid. Funny you mention sloppy work, I bet this truck was imported between 1930 and 1970 from somewhere in Europe, and just like all those other trucks you see, are still getting the snot beat out of them daily, and still running. Funny, but I look on our roads and all I see are top-of-the-line kenworths/ freightliners etc. that are no more than 10 years old.........
These chaps to a great job without special tooling. Not a torque wrench in sight. Great stuff.
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.
@@e-curb they also didn't even tear the diff apart to see if anything happened to it
