Removal of the tail lightDisassembly of the gearbox shafts
Place the shaft in a vice in such a way as to facilitate the disassembly
operations.
Important
Take care not to invert the positions of the shims on reassembly:
this would potentially lead to jamming when using the gear selector control,
making it necessary to reopen the engine
crankcase.

Shimming the shafts
Before assembling the crankcase halves, calculate the shims required to
obtain the correct end float of the crankshaft and
gearbox shafts.
To determine the correct shim thickness proceed as follows.
Shimming the crankshaft
After having installed the new main bearings (with bushing (a) or ...
