How To Caterpillar D8k Bulldozer Tube FinalDrive Repairing Complete Process

[@ACatKrom]

By the looks of that nut, these guys worked on this thing pretty recently, and watching the repair, they will be working on it again in no time

[@scotabot7826]

You better believe that. I so admire their dedication and hard work, but these repairs can't last more than a few hours, if that. Where are their dissassembly and assembly manuals. Parts book?? There is no telling how many seals and O-rings are left off in the re-assembly!! I feel sorry for these guys, but the old saying, "Igorance is bliss", still stands today!!

they do a really good job, its pretty freakin hard to do repairs when you have a limited acces to tools and workshops...... the repairs they do might not be approved or allowed here in the west, but it works for them..... they repair the parts, not just changing them.... well done.

I imagine that you are a painter or singer in a group, that's why you have no idea, this is one of the worst works of this that I have seen, more than anything because of the machining, there it is, without measuring, behind them they have the compasses to outdoors but they don't know how to use them

they are not afraid of anything... , they are making difficult repairs of complicated machinery, and yet nobody there had an idea to make simple workshop lifting tools, transport chariots or proper workbench. Why? Do they really prefer backbreaking efforts of lifting heavy components bare hands and rolling gears in dust?

1. Let's hit the end of the bolts with a hammer so the nuts won't go back on. 2. Every other operation requires a hammer. Advanced guys get the big one. 3. Drop all the gearbox internals into the dirt. 4. If you don't have a hammer, a pair of pliers will be ok. 5. A screwdriver is better than a cold chisel. 6. Ensure the Gearbox internals get a good covering of dust/dirt. 7. Drop internal gear on the floor and let it roll around in the back of a truck. 8. Weld shaft, letting weld splatter get distributed all over gear surface. 9. Centre shaft and gear on the lathe by eye. 10. Hammer fir for bearing, no H8 tolerances here. 11. Spray some obnoxious degreasing agent everywhere. 12. Make sure (probably) carcinogenic solvent is well distributed on bare hands. 13. Re-fit transmission cover without sealant on mating surfaces. 14. Fit-ring seal by stabbing it with a pointed instrument. 15. Never did see the welded bit done, or the bearings put back in.

Rough as guts. If there was sealant used it was not shown, right at the end it looked like the new seal was damaged, chipped pinion tooth at 30:55. There is only one way to assemble those heavy parts and that's to lift to the right height then slide them in STRAIGHT. No jiggling around getting it on then trying to lift into place, that's how damage is done. If they can't afford a forklift then make something up to lift and hold.

Most people would not call 33,000 tries "relatively easy". Even with the dribbles of information that Pakistan had, they probably had to try a few thousand times first.
