| 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.

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?
