Is there a way to figure out the problem with a track not turning without a diagnostic test. Not sure what to do next. No dealers around here.
Check if there is any oil coming out of the casedrain. Always a good starting point.
May want to check pilot pressure to the pump controls on the side you are having trouble with. It will help to see if it is the control side giving you trouble or the actual hydrostatic portion.
I don't see a case drain in the parts manual. Is there one?
Is there a specific location where I should connect the pressure gauge.
There is a casedrain on the drive motor usually the 2nd largest in diameter. If possible disconnect it of the side that's not working and plug that hose. Now start the machine, operate the control for the track and see how much oil is coming out. If it's pouring a big stream of oil you have a failed drive motor. Dribbling out is good but the problem is elsewhere.
Maybe you can get to the fittings on the pumps where the sensors plug in and check the pilot pressures there. Number 11 on the parts diagram.
I think your case drain is the top lines coming out of the motors. Where fitting number 27 is.
