Mount the annular oil seal rings on the adjustment nuts.
Grease the adjustment nuts threads with sealing paste   LOCTITE 518

NOTE:

Before  mounting, the annular oil rings will be immersed in oil 80W/90.

Mount the outer rings of the differential gear

bearing in the half crankcases so that they are
protruding as compared to the inner side of the
half crankcase.

Place the  differential gear in the right side half

crankcase.

Place the left side half crankcase and

Tighten the adjustment nuts by means of the CV

377 wrench, until they come into contact,with the
outer rings of the bearings.

1. REUSED BEARINGS

The reused bearings shall be mounted freely, without clearance.
Tighten the adjustment nuts until the bearings rotate freely, without any clearance.

The new bearings shall be mounted by

pretightening.

Tighten the adjustment nuts until the bearings

show a certain resistance to rotating.

Check the pre-tightening of the bearings as

follows:

- rotate the differential gear several times, in

order to set the bearings;

- place a thread around the differential gear

casing and draw the thread by means of a
dynamometer; the differential gear should rotate
at a   1 - 3 daN force.

NOTE:

For both types of bearings , the nut (1) in the right side half crankcase shall be

tighten more, in order to obtain a bigger clearance of the tooting.
