I looked at a cat 955c track loader that's not too far from home. I need something like this to clear out brush and trees in old fence rows. They want 3500.00 for it but it has a miss and somewhat of a knock in the engine and seems low on power. It may be an injector not sure. I have rebuilt many motors but never a cat motor usually tractor motors. Are parts available for these old engines? I think its a D315 motor. It has good oil pressure but definitely something wrong with it.

There are people WAYYYY smarter than I but I have not had any problem with getting parts from CAT or aftermarket

I watched the owner drive this but I didn't drive it myself. It doesn't have a power shift but do they have a reverser or do you just have a normal transmission.

The 955c is a serie 12a and have a standar normal transmission

If you get to s/n 12A5793 it changes to a D6 size undercarriage.

this serial number is 12A6676

One like this?
