Hello to members, hope I'm in the right place. I'm hoping someone can suggest a fix for my transmission issues.
I'm currently rebuilding the gearbox in my '55 Healey and it seems to be in reasonably good shape except it has too much end play in the layshaft. The manual calls for .001" to .003", and I have .012". The fix was thicker thrust plates, but apparently those are now unpbtainable. There are bronze plates for newer models available from Denis Welch, and I have read of people making and modifying new ones, but mine seem to be hardened steel and I'm not set up for heat-treating.
I could just add a .010" ring of shim stock, but this doesn't seem like the place for that.
I also plan to replace the bearings as they have some small play between the races, and wondered about replacing the synchro rings. AH Spares sells rings that just press in. I wonder if anyone had thoughts re: these rings versus the ones that must be machined.
The bushings appear to be good throughout. I can get no play in any of them. The synchros appear to be almost undamaged, but it seems this might be a good time to replace them while I have the thing apart.
I would appreciate any thoughts people may have. Thanks!
