I pulled the gearbox on my 1973 TR6 with the intention of replacing seals and gaskets, as well wanting to degrease the exterior and inspect synchro's, etc. I've now run into several issues;
(1) Trying to remove the rear extension housing but the rear bearing seems to be seized on the main shaft. Is that common? Any advise on getting it off?
(2) I removed the top cover and got the three selector shafts out to give the brass (?) selectors a good cleaning. I may regret that because now that I look, the three spring loaded detents don't have a screw on cap - they're covered with plugs (like tiny freeze plugs). I seriously doubt that I can get the detent balls back in place without removing the plug and springs. Moss and TRF don't reference these plugs (or bucket type plug, as Moss lists them) and my Robert Bentley shop manual doesn't even mention these - only screw in type plugs. Is there somewhere else to source these?
(3) Once I had the top cover fully disassembled, I ended up with not one, but two, identical small pins. I know that one is called the interlock plunger by Bentley and goes in the 3rd/4th selector shaft, between the two interlock balls. For the life of me, I have no idea where the second one goes. I hate ending up with extra parts left over!!
