Went to reshim the drum this evening and took a closer
look at the shift forks - at least one of them is toast -
a very nice deep arc groove machined into it by the clutch
dogs. One other similar but not as bad. I'm also missing
the hardened washer underneath the speedo drive.
Does anyone have a source for used shift forks (new
they're $160.00 from MG!) and perhaps a hardened washer
laying around they'd part with? Mark?
Thanks -tom.

I have the old nut, it was staked, but difficult to tell
how well oringnally as it did unwind as it chewed
through, raising the "stake" up.

Hi Tom,
I suppose that is one possibility. Looking at the nut,
were you able to
see where it was staked? I would think that a lack of
staking - or a
failed staking - would be the most likely culprit.

Thanks for the hints guys - put it up on blocks, a good
whap or 3 and it was out. Just too chicken to hit it
hard
enough the first time.
Interesting find though in the disassembly, the rear
cover
had been put on with no gasket, and the rear layshaft
nut
came off pretty easily, as did the Clutch Boss nut.
Everything I've read says shim w/o the gasket, then add
the gasket on final assembly as this allows for heat
expansion. Could this have been the cause of the
original
issue with the layshaft retainer nut - heat expansion
causing it to rub against the case?

Oddly, the one that I fixed had an input shaft thata few good whacks to get out. Makes sure all fasteningschristian
are off, putt down some padding, set the tranny on the
flange for the rear cover, and whack it with a plastic
hammer.

Any thoughts on why the input shaft is being so
stubborn?

Surveyshafts.If it shifted OK before, no need to reshim theshouldI repaired one just like you describe (hole punched
through case)
last fall. Just tighten everything well, and itoutwork if it was
working. In your case, the nut on the aft end of the
shaft may also
have been loose, causing the crunchy shifting. Takechristianthe output
shaft and make damn sure you have the front, ccw
tightening, nut
fully seated. Use red loctite on it and punch it
thoroughly to
prevent loosening. Then shim the drum.

If anyone has any hints on what to look for, and
