I used to worry that my workshop was too dusty, after seeing this, I now add dust
it takes up any gear lash. works great! Sawdust is better.
@@AffordBindEquipment Well saw dust holds the fluid/s much better over a longer period of time. OH, and works as an agent to capture any sand or other debris until next rebuild....
There's no dust some gasoline can't wash lol.
Their kitchens are just as filthy. What do you expect
Kkkkkk 🇧🇷
Using a precision torque wrench as a breaker bar with a pipe for extra leverage .priceless !!!!!!!
No worries; someone gave it to them so it doesn't matter!
They are rich bro
All you have to do is bend the indicator back to zero and you're golden. /s
I did not see any precision torque wrench.. I saw a beat the f up old beam or deflection type which was not used to tighten and might as well just been a long handle breaker bar.
I thought the same thing. Now it's a un-torque wrench.
If anyone is wondering the accent is Chipmunk, the worker’s names are Alvin, Simon and Theodore.
those mechanic robes are excellent around rotating equipment, and the sand absorbs all oil spill so no cleaning is required
Hard toed sandals as well.
poor to the environment
They machined the friction disc teeth away. The differential is no longer limited slip! They just added a major defect.
When I saw them grind the teeth away, I thought to myself... (So a limited slip diff is defective and must be open?) Sarcastic internal laughing follows.
Beat onit
I thought the same thing.
I thought they were machining a weld prep for a new set of teeth.
I'm assuming the clutch pack was causing problems so they made it inoperable so that the equipment could still be used?

А зачем они самоблок спилили?
И это не гипоидная. Гипоидная со смещением основного колеса, а тут смещения нет.
В чем был износ? Зачем точили фрикционные кольца?
As they have now machined the teeth out of the intermediate plates this differential is no longer in limited slip operation .
Exactly right, but why would you want an open diff ? I can only think to cut tyre wear, but you'd lose push into a pile ...... their nuts.
@@MUDNROCKS You wouldn't get much function out of that diff the friction plates were knackered anyway
yeah.....that's what i thought.
That's not fixing a "Defect", that's just removing the function of LS. So I wonder why they were doing that to begin with? I'm guessing it still functions, might be noisy and obviously loss of traction, but unless there was something gained seems like a lot of work for little (if any) reward. I suppose at least the oil get's changed (Maybe??? lol). I don't know that I'd say this was an "Experienced Mechanic", more like necessity in a third world country maybe.

@@huh4233 I live in the middle of nowhere In a third world country! Yup! These Cats still kicking!
Wait so you have enough experience to let us know the reason why they basically disabled the limited slip differential?
No more LSD! 🤣😂😂 Major defect repaired! 😂🤣👍🏿👍🏿👍🏿👍🏿
No LS oil
I'm not a mechanic but shouldn't there be several friction plates in the pack? Would removing the teeth from one make the LSD non-functional?
@@mikeall7012 If you use wrong oil in LSD diff, it will start to bind. They use Camel piss or something as oil. It doesent have LSD additives and lock will stick. They just disabled LSD.
@@juhomaki-petaja gotcha. Thanks for that explanation. I was having trouble putting all the pieces together.
I love the clean working in the dirt environment. Great for the innards of the gear.

I know from personal experience, once these backstreet mechanics get hold of your broken down machine, it is the kiss of death...Their methodology is, do half-a-repair to keep the machine going, then it'll be back when it breaks down again & that's more business for them...an endless & infuriating illogical vortex that is best avoided at all costs...
definitely, they forgot to put a gasket on the main drive shaft. now it'll leak oil and then it'll be back and need to be removed with a crane again, extra charge
For this part of the world, it can't be avoided because it's probably the cheapest way to get mc running and the other options is too expensive for them
What are you talking about? They are top notch, he even gave it a karate chop at 12:08. Not just any regular mechanic does that.
@@gungrave10 Doing a half ass job is way more expensive than fixing it right the first time always.
@@TheFeller1554 not for them apparently
I'm sure glad they have their best mechanics working on it, the good use of torque wrenches, and the new and improved semi-limited slip differential it's a winner. I'm very glad they used all the updated PPE's. Good job lads!
"new and improved semi-limited slip differential" LOL
@@ngrader I'm glad you liked the comment. I worked on many different styles diffs, but this one took the cake, still gotta learn a lot more from them. Cheers

@@subtleusername5475 imagine being poor AND stupid? Good one idiot
Well, more like unlimited slip diff. Beacuse who likes limitations?
Every after-sales business unit that's part of a drivetrain corporation needs to see this. I worked for a large German diesel manufacturer for many years, and the majority of corporate had no idea this is what field service looks like in many countries.
No
А ему безразлично в целом, что происходит с техникой после гарантийного периода. В идеале для него техника на следующий день после завершения гарантии должна разваливаться и сгорать.
That’s why Japanese, Korean, and Chinese Heavy machinery are taking over! Germany is clueless
I don't get it what are the manufacturers supposed to do about these guys.......
As the chief safety officer and engineer for the country, I approve the use of the special safety pyjamas and safety sandals.

@@MikeZak101 They are doing it for years so I think their customers are happy.
@@harmandeepsingh9496 there's a difference between happy and no other choice
That’s why I respect these guys and hate American way because it’s way to expensive to do anything because there’s so many safety 3rd party bullshit and it only slows down production and raises the cost to astronomical level but these guys across the world with the most basic tools just get it done without the bureaucratic clutch, Americas always have to deal with.
Причина выхода из строя - попадание песка при прошлом ремонте :-)))))
The good thing is they finally found the wrenches they lost last time they opened it. What a waste of my time, some babuin with a cam, filming a differential assasination and make a dime from that on TH-cam (LOL)

@@stevenhorne5089 ... none of this is nuclear it's just oil
I worked at an industrial gear shop for a few years. The lack of everything was driving me nuts. No measuring. Forcing bearings in place. I wish I could give these guys a bearing heater. I have seen worse though. Work with what you have.
You've seen worse than this? Please tell me more 😃 🤣
@@PatTheRiot mate, had a loader crap it’s gearbox in the middle of a muddy field. Driver pushing to hard to get out of the mud hole. No way to recover so repair done in situ!

I am impressed by the number of men working as they start during the day and only stop at night. My congratulations to all of you, with each video I watch I am more impressed. I'm from Brazil and I watch several of your videos.
pulling the clutch packs and taking the teeth off them was probably just to scam a few more hours labor out of the owner. otherwise all they did was put some new bearings in.
you could definitely be a fleet managers for a company.
Actually it is MUCH worse than that, they turned a limited slip differential into a regular freespinning diff.
Those teeth are to supposed to lock the output shafts to the housing as more force is applied to the plates inside, and now they're just going to be spinning a tire instead.
Good luck to that operator next time it rains and he actually needs to push on something.
@@nickopedia5669 1 wheel peel.

@@AbChauhan they are scammers who fucked the machine up and should be made to say sorry before being violently re-educated
I like how they got the gasket maker almost all of the way around the cover before bolting it in place. At least it will only leak in one small spot.
Hey bozo's he is not using that "gasket maker" to create a seal. He is using that to hold the o-ring in place while he moves the plate perpendicular to the ground while installing it in the correct position...

@@LTVoyager spoken like a fucking 6 year-old, for sure. At least you stopped short of "I know you are, but what am I?"
"That an Experienced Mechanic had repaired"
Ima come right out and say it. This whole video was an experience. A roller coaster of thrills, spills and inappropriate use of tools.
I'm pretty confident if that loader didn't have a problem beforehand it does now.
I agree with Bob W. There was no "defect". They have altered the function of the differential.
Yep, they destroyed the LSD part of it. LSD's only give trouble generally if you put the wrong oil in it.
The effectively took the "posi" out of it by not allowing the spider gears to engage with the clutches.
i was wondering about why they wanted to make the clutches not work, wierdness
The clutch pack in the diff won't engage anymore tho it seemed like a lot of work to make a machine less capable but i have seen it before, i would be interested to know what is the reason to do such modes (most of the time it's about saving a buck).
@@walidben7893 The question is; what are You accomplishing by turning a posi unit into an open diff? I spent a lot of money to go the other way on My car.
I love it when you make them sound like munchkins
My god... I really hope these guys get paid piece work, because who the hell could afford to pay 6 techs to do the job 1 guy does in a proper shop? I guess it helps that you can guarantee you'll be seeing it again soon enough. Because the machining was a nightmare (and I'm pretty sure it did more damage than it helped), and you can guarantee all the bearing surfaces, oil seals and fluids are heavily contaminated with sand. . Job security!
I'll bet that whole job cost £25.00.

man this is painful to watch but the respect I have for these Mechanics for teh conditions and tools they have to use and work in......... this you I am so lucky to have the tools and service truck I have this is usually 1 man 2-3 hour job and no machining as we have the proper parts in stock but they are very ingenuitive and well my respect to them 100%
I have a lot of respect for these mechanics, it is near impossible to get this much work done without proper tooling ,let alone a proper work place.
Oh yea major respect someone has put the wrong diff oil in or they've run it way to low causing the plates to lock up making turning ruff then took it to these cheap cunts instead of putting new friction plates in and lsd oil they lathed the teeth off so its open diff just gonna have 1 rear tire spinning now while driving into a pile of rocks so yea major respect
Also seen no paint on the ring gear to spin and check the tooth engagement after new bearings might eat the ring and pinion over time bet when that happens they will just pull the rear drive shaft have a fwd loader very professional
Respect for risking their own life? I am a mechanic and there is many problems with this called repair.. That is one thing but also a huge issue is to someone going under an equpment hanging on a crane rope. Hell no... Just pure stupidity.
Definitely interesting when changing the structural design is considered a repair.....
The bits when they are putting it back together and can’t figure out the order are hilarious… when they are scratching their heads at how the friction discs were packed was my favourite
Like watching and listening to Jawas work.
Honestly; I shudder at the bulging plastic bag that comes with every flat pack, but these guys take this apart, but most importantly, reassemble it without a page or booklet. I tip my hat at the ability of these lads to do such work, in less than ideal conditions, but most of all, taking the millions of complex parts and put it all back together. If I done it, I'd have more than one jar of spare bolts and washers..

it seems that they've removed the differential blocking ability... the grooves in those inner rings were meant to act as a brake when pressed against the other alternating plates that have the slots to hold them on the outside...
yep they made it an open diff. they prob don't have the correct slip additive on hand so they did all this instead. the work looks smart and impressive but it prob only needed a flush and a fill with the correct fluid combo.
@@Nathan-gj8ch I'm also willing to bet they reused the old diff fluid as well.

There is no doubt this differential will run like new now that it has had an infusion of dirt, no torque on bolts, and no gaskets. Well done.
and no run-out or lash checked.
tiny bits of glass in that dirt
And the teeth removed from the friction discs
I should start a business selling cheap work benches in these countries. How do their knees even work anymore???
Might be a good opportunity tbh.
Blow their damn minds with a ryobi 18v 1/2 driver.
Looks like they are converting a limited slip diff into an open diff, probably for a tighter turning radius or to conserve tire life.

This is a new level of service. Even the best authorized workshops do not have such specialists.

What makes no sense is they are notoriously known for destroying rear ends now they claim its Cats fault. They are smoking some bad shit making them ignorant. Maybe it's that tea or whatever it is.
I'm baffled
There are many possible mistakes and dangers in this type of work. There is no academic knowledge or skill behind this. Just experience
Yeah, experience in doing is wrong.
Brilliant rebuild, I dont think they could have done it without the minions helping, Pretty sure I heard stuart giving directions in the background. Cheers from Canada !

That's about what to expect from a Cat authorized repair here in the states also.
They have funny voices this people.
I give these guys credit they work with what the have,it’s like they are old school witch I admire
It’s because it’s a 3rd world country. They know no better. Which is why they all move in their millions to countries like the UK or other countries. To ruin those counties with their Stone Age mentality
Ok guys this bit of gear is about $300.000 so only drop all the parts in clean dirt. And if the bolts are tight get a bigger hammer. And if we have parts left over we can put them in next week because it will probably be back.
All of these videos are actually good advertising for CAT durability and ease-of-repair

The high-pitched voices and all the tinkering reminds me of the Jawa from Star Wars.
What problem were they having with this diff? As a retired mechanic I was dismayed at what I saw here. Filing the teeth off the LSD friction plate! Why, you now have rendered limited slip useless. Using a cold chisel to hammer a bearing into place! I see one fellow broke off the bolt head on diff housing, but showed not replacing it. And, no gaskets!!! But, you have to give them an A+ for effort. They only can do with what one has on hand! I enjoyed the various responses.
My hats off to them they're doing the best they can with what they got they're making do. There's a good chance that Cat was bought at auction in Australia and shipped there already worn out and they're grateful.
There was nothing wrong with it.
The shipping itself would probably be way to much than they could afford
