Remove the differential assembly by unscrew the eight screws of the casing.
Dismount :

- the screws that attach the differential nuts lock washers (1);
- the differential adjustment nuts (2);
- the stub bolts nuts that attach the bearings half casings  (3);

Remove the centering bushing and unscrew the stub bolts.
Together with the conical balls bearings, remove the differential assembly, detaching it

from the front part of the drive pinion.

Remove the differential drive pinion together with the conical balls bearing from the

differential casing.

Dismount  two rim attachment screws, on opposite sides.
Depress the bearings by means of the CV 28 A  extractor, provided with CV 48 claws.
Dismount the rim ; do not reuse the screws.

EMO UNTING

The differential gear shall be re mounted by performing the dismounting operations in

the reverse order.

Before mounting, the component elements from the differential casing, shall be 

lubricated

with T 90 or T80 oil.

Mount the following items in the casing:

- 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

casing by means of the ten self lock screws ( use new screws).

Tighten at the required moment of  9 …… 11 daNm

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.
