- Separate the crankcase by keeping assembled the
driving shaft on the half crankcase, flywheel side.
- Remove the coupling gasket
N.B.: The support bush can be maintained in the half
crankcase, flywheel side.
Driving shaft disassembly
- Before disassembling the driving shaft, check the
timing with the countershaft. Perform this check by
turning the driving shaft until the two holes on the
driving shaft are aligned with the hole on the counter-
shaft control gear.
This position also allows for the driving shaft removal.
- Remove the driving shaft with the shim washer,
flywheel side.
- While separating the crankcase and
removing the driving shaft, take care that the shaft
threaded ends do not interfere with the main bearing
brass. Failure to observe this recommendation may
cause damage to the main bearing brass.
Warning
Removing the countershaft control gear and the
oil pump.
- Remove the control gear by acting on the 4 fixing
screws.
N.B.: The head screws are blocked with LOCTITE
thread locking compound. Take care not to damage the
control hexagon. To achieve the best results, it is
recommendable to use a hexagonal socket wrench.
Remove the gear only when necessary.
