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. .

Hard to watch. Precision parts,in the dirt. Kudos to those men for the hard work.

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.

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.

The repair keeps the machine working till next time. They are doing the best they can with what they have to work with.

Dirt and precision ground bearings should never come together, until you learn that you will never produce a long-lasting repair.

You obviously don't work with earthmoving, it happens alot.

These are some of the best bush mechanics I have ever seen on KZread.

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!

I knew I wasn't the only guy who works on heavy equipment in sandals

Graduates of the "See you next month" school of heavy equipment repair.

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.

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!

Keeps the o ring from slipping out I guess--Old Cat mechanic here.

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.

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).

Drink every time you think to yourself: "Nope, that'll never work." :)

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.

I love the DIY Dial Gauge (piece of number 8 wire)to centre the work piece in the four jaw

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.

It’s such a big job replacing anything on those large frame low drive dozers…dangerous too…those pullers are no joke!..

Watch dem der toes Abdul.

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.

To the guy who did all the welding👈👈👈👈👍👍👍👋

no fingers or toes lost in this video great job guys

Perhaps foreign aid in the form of steel cap work boots and overalls may be helpful maybe some workshops as well

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.

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 ✌✌✌✌✌

Awesome job

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.

31:36 just sprinkle a little of sand onto precision part and the job is done :)

Very hard work BRAVO

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 👏

impressive

Safety sandals and dirt, conditions are improving .

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.

Headed to nearest Richie Bros auction near you😂

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.

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.

For job of this size I wonder what there quota is for the number of parts that must be thrown in the dirt?

Before a spanner went near that job it should gave been power washed like hell....

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?

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.

Mad Max Style

Do you think they isolate and lock off during repairs? Do they go through a permit to work and have any RAMS?

Those segments are sharp enough to shave with, better change them out too.

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. 👍

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!

those bearings are begging for more grease inside the cage.

some extra sand should do the trick ;)

We completely rebuilt dozers in the mud back in the 70s, out on the grade, built around it, never thought anything of it.

And everyone is wearing their OSHA approved safety sandals.

...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

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

These guys are all certified CAT mechanics

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.

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.😂

God the comments from people criticizing how they are in dirt 🙄

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!
