Lee, as I showed in the earlier
HST part of the project, the
HST itself is
in fine serviceable condition. Gears in the main gearbox and rear diff are
what broke. It is plausible to me that the tractor was run for a while with
an oil-fouled clutch, which caused lots of chattering and vibration. This
led to driveablity issues and difficulty shifting. The operator forced the
MFWD lever so hard the fork broke, releasing the detent spring, which got
caught in the diff, shattering the ring and pinion gears. That's my guess,
based on the evidence I have seen and how the detent spring is retained.
If anything, this project convinces me more than before how robust these
HSTs are.
