You have got to admire these blokes , no coolent on the lathe and I used to be a plant fitter and I cant imagine working in sandles , I still wear safety boots in my workshop at 72yrs old .
True Engineering Specialists!!!
its easy for them to take another person lol if he dies im sure many been injured for life. and then do reapirs on a sand bank? sometimes they put berarings on bare sand
He should really be wearing steel toe sandals for safety.
Yup!
What about eye protection for the "machinist"? Let's all just agree that these people do not know anything about safety. I wonder if or how anyone gets paid. .
Dirt and precision ground bearings should never come together, until you learn that you will never produce a long-lasting repair.
as long as it drives out of the yard!
Hola
You must realize that they are doing the best they can with what they have to work with. And I'm sure they clean the dirt out before reassembling.
@@dougalbyrne2817The Guys are clever. In 4 Wochen gibt es einen weiteren Auftrag zur Reparatur😅
You obviously don't work with earthmoving, it happens alot.
Hard to watch. Precision parts,in the dirt. Kudos to those men for the hard work.
Yep, precision parts in dirt, apparently no new gaskets used to seal covers, and am I wrong, I didn't see any grease applied to those new bearings or very little. And I never see any missing fingers toes or real safety equipment. Crude working environment but my hats off to the mechanics for getting the job done. Replacing tracks without cranes, jacks or lifts is impressive!
Missing fingers make it run better...
I was thinking the same thing. Working in dirt. How long will those bearings last?
I saw them putting new grease on
@@HobbyNut-sy3loI bet many are missing a few
I was thinking the same thing. At 41:45 one of the guys is rolling the seal around in the dirt. He even sprinkles a little more on it to insure a failure in the future.
These are some of the best bush mechanics I have ever seen on KZhead.
As a heavy equipment mechanic for over 45 years, this scares the crap out of me. One has to wonder what the life expectancy of a repair like this is.
In germany we say "von 12 bis mittag"
It's all sketchy AF but I suppose it beats the equipment not working. Labor and shop time are likely dirt cheap there, much cheaper than getting a new part, even if they have to repair it every 6 months. I still get a kick out of watching, these guys probably have zero formal training but still manage to get it (sort of) done.
About 100 hours +/-50. This is how it is in these countries. I have first hand knowledge.
These guys are the real thing, in the field with limited resource. Give credit where its due.
The repair keeps the machine working till next time. They are doing the best they can with what they have to work with.
I knew I wasn't the only guy who works on heavy equipment in sandals
Pristine conditions for the repair and the precision implements used when machining must be commended 👍🏻👍🏻😁
Eh? Learn English, as you sound illiterate.
Welding in the lathe with the earth going through the spindle bearings, never, not even on a cheap lathe, also the guy under the heavy housing with just a fan belt holding it nuts.
ive done about 200 final drives in my time, fair play that they have done this in the field without the proper tools, but jeeze! how have they still got fingers and toes to start with? when youve popped the sprocket just go a bit further to release the bearings would make it easier. bet the dead shaft threads took a beating, keep the nut on! i dont understand the dust on the duo cones, use swarfega . didnt see any preload on the bearings or red gasket seal. if my memory serves me right its a six foot tube and average size man with sprocket turning for the preload. would have been nice to see the state of the top pinion gear into the steering clutches. a couple of long bolts with the head cut off would make the case go on easier. good work though, not an easy job in the field.
Working on a Cat dozer with hand tools is next level.
Нижний и это так ,😢❤
Yes, always use some dirt before installing the new seal! '31:40
Oil, grease and sand lube, good stuff!
I had convinced myself that I had hallucinated that part! lol.
Это заявка на следующий неизбежный ремонт. Так сказать вызвал клиента
I had to back and look! Wtf.??
I literately just paused the video to see if I wasn't the only to one to have noticed that! 😂 edit: Also dude is stabbing at the seal with a flat head to get it in. 🥲
Come over to Alaska....Tony Beets would fire his mechanics and hire these guys on the spot!
LOve it. 27' Spend ages precisely redoing part on a lathe and then drop it in the shit...
I've replaced bearings on a crawler. I had access to a welder and torch. Heat and homemade pullers and an air over hyd. Porta-power got off one side. The other side, I had to cut the race and use a chisel. I cleaned everything up and polished the shafts prior to putting on the new bearings. I try to make it "surgically" clean. I've also rebuilt big flywheel driven punch presses. I rebuilt an 800 ton coining press, a 600 ton, three stage press with a six ft. Bed and a 2450 lb. Inertia weight (flywheel).
When people post comments about the lack of this or that such as oil or grease...etc you have to remember that this job probably took days to complete. The video is only a little over 41 minutes so you don't see everything. Personally, I think these guys do a fantastic job all things considered.
Graduates of the "See you next month" school of heavy equipment repair.
Thats how I do it...Throw dirt on A new Duo Cone Seal......
Keeps the o ring from slipping out I guess--Old Cat mechanic here.
I love how these Guys Can Fix Anything. America Used to be that way. But the thing that always has my mind Wondering is Their Man Dresses they wear everyday, they look like they never Change. I also know Water Is Available But They Seldom Wash Their Dresses.
cont....Another things to consider is the Cat D8K came out in 1974. Someone has kept her running all that time so someone must be doing something right.
Probly not these guys tho !!!!
Drink every time you think to yourself: "Nope, that'll never work." :)
Under the circumstances of making do with what you've got, these men are experts. They are not your typical Western 'Replacement Monkeys' in clean weather-proof workshops with all the bells and do-dads. The bearings and seals were the only new parts I spotted and they may well have been local knock-offs. Amazing that they all seemed to have all fingers!
31:36 just sprinkle a little of sand onto precision part and the job is done :)
Hey that D8K final drive sprocket. My boss in 1976 RAngus CAT dealer Alberta. Showed me this as a 1st year apprentice. Thread on the button to the dead axle . Use a 20 lb sledge and about two three solid hits pops the sprocket from the taper 😂 Well I tried the other side and near puked hitting that . I put the press assembly and puller legs on. Pops at about 40ton average.
Perhaps foreign aid in the form of steel cap work boots and overalls may be helpful maybe some workshops as well
I love the DIY Dial Gauge (piece of number 8 wire)to centre the work piece in the four jaw
Watch dem der toes Abdul.
It’s such a big job replacing anything on those large frame low drive dozers…dangerous too…those pullers are no joke!..
You guys didn't even seal the bull gear housing, how's that going to hold in oil? Should have used some type of sealant!, but great job, especially in those conditions 👏
To the guy who did all the welding👈👈👈👈👍👍👍👋
Unfortunately, you don't have the important tools to repair such heavy parts. I apply your will. You are good technicians. I would have warmed up the ball bearing; it expands better. I wish you all the best BRAVO ✌✌✌✌✌
I guess all the dirt and sand and chewed up gear teeth are ok. I'm impressed that they could get it done at all, but I suspect the life span might be kinda short.
no fingers or toes lost in this video great job guys
The Cat D8K was first introduced in 1974, and the power-shift models, as featured in Shaun's photos, were produced until 1982. During the production span, it is estimated that around 28,900 units were manufactured. The ratcheting socket wrench, with interchangeable sockets, was invented by an American, J.J. Richardson, of Woodstock, Vermont. The tool was patented (U.S. patent 38,914) through the Scientific American Patent Agency on June 16, 1863. The first illustration of the tool appears on p. 248 of the April 16, 1864 issue of Scientific American. In Pakistan they haven't made it there yet. 161 years behind us as of right now.
No pressure washers or work boots in this country?
Зубья на малой шестерне не стали восстанавливать.
Before a spanner went near that job it should gave been power washed like hell....
For job of this size I wonder what there quota is for the number of parts that must be thrown in the dirt?
I'm very skeptical about this repair, considering tools and method, and I wonder how long it will last....before breakibg down again... Very little! 😅
I like how they drop all the parts on the ground did it in the dirt and the guy doing the welding and machine work on that shaft using a pair of dividers or calipers to see how much Morias to take off yeah you’re within 0.009” when the tolerances need to be 0.0003. Another good chance he’ll Ron leaving the shop, but the warranty and life expectancy of it is not very long.
S3 Sicherheitssandalen, top.
those bearings are begging for more grease inside the cage.
impressive
勤劳，智慧的巴基斯坦师傅们
hard workers ..but it been painful to watch...something tell me they gonna redo it
Якши АХМЭТ! 👍
Should be titled “How to Give OSHA Inspector a Heart Attack”
A family friend worked in PK in the 1970s. One of the stories he told was how Volkswagen factory people had hard time trying to teach their local mechanics to put parts on a table when working on them, rather than doing the work on the ground.
Nice work boots
What do the techs and engineers at Caterpillar think when they see this? Hmmm....
31:34 Притрусил глиной - зачем?
CATERPILLAR authorised repairer... Pmsl. Remind me never to take my dozer to this place for repairs! Oil, sand, grease, and I'm guessing they've never heard of a torque wrench! Did they even fix the stripped teeth on that gear? Nah, it'll be right for another 10,000hrs.
Very hard work BRAVO
Awesome job
Через видео прямо таки чувствуется запах редукторной смазки, жара и прочие адские условия работы.
Strange how ingenuity stops when it comes to working conditions. Like shading the light so it does not blind you when working on the lathe.
someone get these boys a milwaukee impact and a dial indicator!
Safety sandals and dirt, conditions are improving .
Buldozer buatan Amerika ini tembus juga sampai ke negara anda ya..!
Damn! That hurts my eyes. Having worked with heavy machinery, including a Caterpillar dealer, this is backyard shade-tree mechanics if I ever saw any. And so sterile. Before any piece of Cat equipment went into the shop it was power washed. I had to change the tracks on a D-8 in a dry and sandy desert wash just outside of Kingman Arizona in the summer of `67. With the crane on the back of the service truck we rolled out the new tracks in front of the tractor, un-pined the link and drove the tractor off the old tracks and onto the new ones and it was a world cleaner than this.
Clever but really not the slightest concept of constructional engineering. High pressure jet wash during the stages would make so much difference. All of the intellect seems to be on the lathe.
Headed to nearest Richie Bros auction near you😂
Очень качественная работа...
if these children had the opportunity to study their potential would be limitless
Why not pressure wash all the shite off the day before??
You can only use pressure wash as one available.
Respect ❤ And Subscribed.
13:25 вот молодцы ребята - даже на ногу никому не упало.
Wath about the big sprocket gear is it not pressured on with a ram ?
Походу это наше будущее!!!
What a big garage and ni impact tool??? Can you believe it removing parts from a gigantic bulldozer with a tire iron lol?????? THats not the way I was taught to pack a bearing!!!! Can you imagine one of those guys coming to a modern Caterpillar repair shop in America?
I love the PPE they use
They didn't address the chipped gear teeth...
Those segments are sharp enough to shave with, better change them out too.
I wonder how many of you poor guys go home without your fingers , i’ve done final Drive repairs in the field, but these guys got me nervous
...I thought I willgo to Pakistan to be a mechanic. I took my own steel toe caps, gloves, goggles etc. On my forst day when I went to work they took all the safety, protection gear I had. They said I can have it when I finish work. When I asked why they did that, they replied safety and protection gear is a hazard on a work site. lol
Mad Max Style
I was surprised they actually bought a few new parts
Nice safety boots
It sure looks like it was running dry.
Yup, my thoughts entirely. Not a drop drained out when the casings came off😂😂
This is what America needs is guys with this know how , The mechanics here go to endless hours of school to learn this and they end up Google this to get answers
Amazing what can be achieved by a group of men working under such dirty conditions. That has been one hard worked D8 the drive pinion gear was a bit rough, thought it may have been getting welded up. Well done you men. 👍
Are these guys CAT certified mechanics?? lol! 😳😳😳
All they’re missing are the Caterpillar patches on their nightgowns.
2:11 - I think that's the first time I ever saw a RATCHET WRENCH used in one of these videos instead of these third world INSECTS using breaker bars for all bolt turning jobs!
And everyone is wearing their OSHA approved safety sandals.
The dirt of India is of a very fine quality, and when it is combined with dung it will adhere to metallic surfaces producing a long-lasting repair.
Curry dung& dust
I can gaurentee this repair wouldn't last long.Probably biggest downfall being the rapid cooling of weld build up would produce hairline cracks and that hub would be coming off in 2( at least) pieces. Also this was two differant tractors, changed about half way through. I have personally overhauled numerous Cat low drive final drives and this one will need a hugh wing and a prayer.😂
Maaşallah.👍👍👍
they must not have any lawyers in that country, or they have very sympathetic judges!
Еслиб наш инженер увидел что без мойки трактор или ещё чего разбираем, отымел бы противоестественным способом и без капельки смазывающего вещества!
31:35 what was there?
These guys are all certified CAT mechanics
some extra sand should do the trick ;)
Proof that with big enough cheater bars, sledge hammers and brute force you can repair most anything! It pains me to see a precision assembly treated this way, but I guess ya gotta do what ya gotta do to git 'er done! Hard to believe the guy on the lathe is getting a proper interference fit to that tapered roller bearing inner race using a spring OD caliper, and transferring the measurement to vernier calipers!
incredible work. How much does this cost in US dollars?
Tyvm!!
Ведущая звездочка изношена и требует замены!
final drive repair wearing open toe shoes wow
Wo endet sich? Video zu Hälfte gedreht
41:45 Looks like some dirt and gravel took out those teeth! Just sayin🤔🤔
notice the safety sandals, all the damage is from no oil
