PC200 Undercarriage Replacement

After about 7800 hrs, my undercarriage is getting tired. Rails are worn through to the pins, a couple rollers are seized, and everything else is close enough to done that I decided to replace it all. Along the way I got a few videos of a couple parts of the process. Wish I had gotten more footage, but I was on a timeline to get it done between jobs. The machine is a Komatsu PC200-6.

If you're going to use a cutting torch then burn the nuts off so you don't damage the pads.
Also try using a 1" impact wrench before cutting the bolts. I have a 250 Litre Air tank which suits the job.
97% of the jobs I do my air gun loosens the bolts.
I've got a 1" Aircat 1992 impact wrench that loosens 20mm bolts & slightly bigger diameters & a 3/4" 1770-XL for bolts 16mm & less.
I have a guy that assists me & we usually do a Pad Swap(roughly 84 shoes), 2 new chains, 4 top rollers & 2 Sprockets in 8-9 hrs but we're non stop from start to finish excepting the occasional swig of much needed water.

Worked at Texas Welding and Press in the 1960's and we did it much differently than you all did. Generational thing I guess. Lots of sledge hammer work with track press and welders on the job for rebuilding rollers, idler, replace/build up sprockets. A young man's game for sure. Thanks for the video.

Chrome sockets on an impact you naughty young man

This was My first job man... So nice to watch and remember

I'm just curious why you're turning your videos into music videos ...look at the context of your videos music has no place.

I had a 1989 PC 200..komatsu motor..grey market..Humboldt County California

Good clip, suddenly I had an attack of vertigo that caused me to stop watching it. And the music was cruciating.

05:06 is there a reason that the mud is left there? So much work, Restauration, cleaning but why always only this partly cleaning?

[iancox]

It's good but leave the music out

[timothyball]

If ya like the music, turn up the volume, if you don't like the music, turn down the volume.

My method is to pull the pads while at a comfortable working height, meaning while the rails are still on the tractor and stack the grouser side down. Cut the rails, replace the rollers, sprockets and drive gear. Roll the chain on, lightly sand off the paint from the rails and the pads that are grouser side down. Throw pads on at a comfortable working height and install 320 nuts and bolts.

I have some tricks along the way but that's the basics.

You need to fire the cameraman it would be nice if you would have actually showed us how to put these parts on.

Good video. When you pumped up the chain you left a lot of slack?
