The boat tranny took a dump. Its a ZF-301C behind a Cummins 450 horse
diesel. Took a trip to the ZF repair shop yesterday. The front of this
tranny has the flywheel transfer plate just press fit on - no key way. To
remove the plate, they hooked it up to 50,000 psi oil pressure on a
fitting in the plate just for this purpose. The interesting part, to press
it back on they put it in a 60 ton press and used the same 50,000 psi
fitting to increase the ID of the transfer plate. Interesting piece of
German engineering. The mechanics there didn't know, but I assume each
piece has a slight taper.

Boat should run again tomorrow.


Just in time!
