Happy New Year!
Additions to the broken 2nd synchro. I've tried to replicate why the dual cone synchro was misaligned when mounting it. When you place it in the sleeve the inner ring tends to hang on the bearing and is pushed upwards out of the synchro set. If you mount it you have to push on the inner synchro ring to make sure that doesn't happen.
So, how not to mount it:
Another question about the mainshaft clearance adjustment. In the initial step I've measured 1.20 mm. When I move on to the final clearance inspection how much has to be corrected? +-0.10 or +-0.20 or even more? I'm going to order the shims in 0.05 steps in the required range (before I spend too much money on ordering all possible shims ).
Thanks again!
