DIFFERENTIAL ASSEMBLY MOUNTING IN THE CLUTCH CRANKCASE
The differential assembly is pressed into the crankcase, then the stopping safety device ( 3) is
mounted on the planetary shaft by means of the C.V. 946 device.
Rotate the differential assembly and check the speedometer pinion rotation.
Remounting of the C planetary oil seal ring is performed after this has been oiled, by means of
the C.V. 945 device and the A protector.
Mount the oiled protector A, on the planetary pinion and position the oiled seal ( C) by means
of the B device.

The internal control
axles must not show any deformations or wear on the milling for locking
ball, and their sliding on bearings must be done make freely, without excessive clearance.
The contact surfaces of the forks with collar of the rocking must not show either deformations or
wear. Ensuring of the control forks axle is performed by means of the balls and springs located in
the holes made in the mechanisms crankcase.
The locking of the control axles is done by means of some cylindrical rolls mounted inside the
clutch–differential crankcase.

The assembling surfaces must be flat (small
imperfections can be eliminated by means of a thin
file). Place the a xle and 1-2 fork assembled on the 1-
2 sliding collar of the secondary shaft.
The two shafts (primary and secondary) are taken
together with the fork and 1-2 axle and positioned
at the same time into the clutch – differential crank-
case.
The c rown and the secondary shaft are rotated
until the end of the secondary shaft fits into the bear-
ing.

With the 1 – 2 axle in free position, the following
are mounted:
- synchronizing a ssembly 3 – 4 together axle
and 3 – 4 fork;
- mount the for pin 3 – 4 by means of the CV
949 device. Mount the blocking roll of the 5 th step axle ( B).
