Fitting the two half-crankcases

Carefully clean the contact surfaces and make sure that the three reference dowels are in the right place. Carefully position the gasket and the clutch side half-crankcase. When the engine is assembled, tap with a plastic hammer in order to match the surfaces properly. Then screw in the twelve fastening screws.

When the engine is completely assembled there should be no play in the driving shaft axle and 0.2 or 0.3 mm play in the gearbox axles.
