Hello Everyone, I have a Komatsu D21P -6 DOZER. I parked it in my shop last fall. I tried to pull it out today. Started right up but when I put it in reverse only the right track turned. Did the same in forward, only right track turned. Tried a few times. Couple of times the engine nearly stalled. Any ideas what could be the issue? Thanks. Doug
I have had a similar problem. changed out both steering clutch plates and brake bands. Worked for a while after that, then right track seized again. I think I've narrowed the problem to the bearing under the clutch lever. Having a helluva time getting to it, though. I'll keep posted it I solve the problem
