Incredible Work How Caterpillar D8k Bulldozer Tube FinalDrive Wheels Repairing Mass Production

[@IVAN-bs5bq]

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 .

[@stoffes]

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

[@scottkuchciak]

He should really be wearing steel toe sandals for safety.

[@boondocker7964]

Yup!

[@taxicamel]

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. .

[@James-ru4jx]

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

[@johnkemas7344]

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!

[@HobbyNut-sy3lo]

Missing fingers make it run better...

[@frankbullitt4556]

I was thinking the same thing. Working in dirt. How long will those bearings last?

[@jameshallahan4376]

I saw them putting new grease on

[@jameshallahan4376]

@@HobbyNut-sy3loI bet many are missing a few

[@BenderOMetal]

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.

[@WeeShoeyDugless]

Pristine conditions for the repair and the precision implements used when machining must be commended 👍🏻👍🏻😁

[@moking8095]

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

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.

[@andiv8942]

In germany we say "von 12 bis mittag"

[@Gyppor]

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.

[@HobbyNut-sy3lo]

About 100 hours +/-50. This is how it is in these countries. I have first hand knowledge.

[@art40odd]

These guys are the real thing, in the field with limited resource. Give credit where its due.

[@peteacher52]

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!

[@yorkshiredaz7632]

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.

[@alvarofernandezvega464]

I´m wondering why is the clay for, preserve thread from sparks? Keep it in a soft cool-down before electroabrassive-grounded electrode welding? Sure you can tell. Thanks :)

[@laserbeam002]

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.

[@OHJUSTFORKU]

Thats how I do it...Throw dirt on A new Duo Cone Seal......

[@oldbowsaw9001]

[@laserbeam002]

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.

[@chrisbrowne8561]

Probly not these guys tho !!!!

[@russellking9762]

Come over to Alaska....Tony Beets would fire his mechanics and hire these guys on the spot!

[@adamanderson5055]

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).

[@nikolaos9906]

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 ✌✌✌✌✌

[@buckburton7318]

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.

[@peterisaloftpc4093]

[@MrMan5014]

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

[@n5ifi]

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.

[@SimDeck]

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

[@steveanderson4768]

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.

[@CaleT_64]

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

[@nemogecici1005]

[@adrianoakes152]

Why not pressure wash all the shite off the day before??

[@FerdiAlbers]

You can only use pressure wash as one available.

[@daithi007]

36:30 Why not rebuild the worn teeth? If you disassemble the final drive, address the worn teeth then.

[@tnesp]

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.

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.

[@donaldpruett852]

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.

I'm intrigued to know. Peace, everyone!

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.😂
