- the propeller shaft pinion opposite to the rim , after attaching the support washer
on the former;
- put in, the four differential pinions and their respective bushings, oriented with the
lock notch in the casing seat;
- put in the ball joint the differential pinions shaft and half shafts, so that the pin hole
corresponds to the hole in the casing;
- attach and push the pins by means of the CV 31 B broach;
- after attaching the differential pinion shaft lock washer, mount the rim on the

The two conical ball bearing shall be mounted by pressing in the differential casing.
Press the two outer rings of the differential drive pinion bearing in the differential
casing.
Put the differential drive pinion in the casing; the former has the adjustment washer
mounted on it and the 30 x 80 x 32,75 conical balls bearing pressed on.
The differential assembly shall be fixed and mounted in the casing, with the bearings
cushioned on half casings.
Tighten the differential bearing caps on the differential casing at a moment of 3,5-5 daNm.
Tighten the bearing adjustment nuts.
NOTE: Mark the adjustment nuts in correspondence with the casing.
Check the mark on the bearings in correspondence with the casing.
To remount the main transmission, observe the following:
1. The pairing of the conical gear.
The pinion and the rim are lapped together.
They are inseparable.
Replacing one of the parts implies obligatory replacing of the other one.
There is a common, corresponding mark both on the rim and on the pinion.
2. The use of a continuous sealing material layer of LOCTITE 518 on the contact
surface of the differential casing and the axle casing (aprox. 5 gr). Operation procedure is
as follows:
- dismount the differential assembly from the rear axle;
- clean the old sealing material ( by scraping ) ;
- clean with solvent the contact surface of the differential casing and of the axle
casing.
