HALF CRANKCASES COUPLING
Both the crankshaft and the multiple gear must be
fitted on the clutch side crankcase half and the
change gear shaft on the flywheel side crankcase
half.
To couple the half crankcases proceed as follows:
- Clean the mating surfaces thoroughly; spread with mastic the gasket to be interposed with putty (on
both sides) and fit on the flywheel side crankcase half.
- To successfully fit the half crankcases together, act if necessary with a wooden mallet on the flywheel
side crankcase half: never act on the end of the crankshaft.

Heat, with the specific tool, the bearing housing
area and fit in its place the ball bearing (1) and with
the tip of a screwdriver insert the retainer circlip
(2).
Wait until the cover is cooled and with the specific
punch (3) position the roller bearing (4). Insert the
inverter gear in its housing, install the reverse gear
command lever and, with light mallet blows, insert
the differential housing, anchoring it with the re-
tainer circlip.

After cleaning the mating surfaces and fitting the
gasket (spreading the mastic) on the crankcase,
apply the thrust washer (5) on the differential cov-

into sliding gear the slider of the reverse gear con-
trol lever so you can pair with ensuring that the two
parts fit together perfectly and lock with the relative
