My 550E long track case dozer has been sitting up about three months and now when I crank it, it will only move on one track, any idea what might be going on with this?
Is the track that is not working, locked up or free wheeling with no drive?
it is locked up
Brake not releasing? Two ranges engaged at same time? - stuck/jammed clutch pack Tracks seized up? Final drive issues? Could be any of the above...... I would be testing pressure at the brakes. Compare the free side to the locked side. It needs charge pressure to release the park brake, maybe the seals are letting the pressure past & won't release??
