CRANKCASE
Reverse the above operations to assemble the
crankcase. Pay special attention to the following
points:
Totally remove the sealer and oil stains from the
contact surface of both the RH and LH
crankcases.
Prior to fitting the sump filter, wash it with solvent
and then dry it with compressed air.
Attach the centering devices to the LH crankcase.
Apply motor oil to the connecting-rod crank end
and to the transmission gears.
Should the engine feature an oil sump gasket,
replace the gasket. Otherwise, with no sump
gasket, apply silicone on the right sump contact
surfaces and to the (A) parts of both sumps, as
indicated in the picture.
Tighten the crankcase screws at the specified
torque.
Crankcase screw 11 Nm (1.1 Kgf-m)
After tightening the crankcase screws, check to
see that the crankshaft, the jackshaft and the
transmission shaft are turning smoothly. If you
notice that there is a considerable degree of
resistance, try to improve the turning of the shafts
by tapping them with a plastic mallet.
