New here. Been working on a ct 332 for a few weeks, trying to catch up on maint that appears to be lagging from previous owner. The problem that I am having at this time is the cover on the sun gear on the left side track is getting very hot while the right side feels just barley warm to the touch. The darn manuals do not diagnose this type of problem. I have made sure the track is clear of mud and debris, drained, flushed, and filled with new gear oil. Does anybody know if this is the indicator to replace the drive motor or is there any thing that I should before doing that.
