The stopping safety device (A) is extracted, by means of a pincers from the differential crankcase
( press on clutch crankcase in order to release the safety ring).
The differential assembly is dismounted using a press, by means of a bushing C.V. 554 ( the
bushing is pressing on the differential crankcase).
Di smount the spacer washer ( 5) and the elastic c oncave washer ( 6).
The crown of the speedometer ( 8) is dismount from the outside of the differential frame.
Remounting of the differential assembly is performed in the reverse order of the dismounting
operations, only this time the spacer that is mounted between the lateral surface of the crown and
the support bearing, shall be positioned with the concave side towards the crown.

DISMOUNTING
In order to extract the big bearing ( 7), of the differential from the clutch-differential crankcase,
a profiled metallic strap is used, which is pressed by means of an extension, at a press.
In order to dismount the other bearing ( 10), first extract the safety ( 9), then press with a press
on the bearing by means of a sleeve with the outer diameter of 50 mm, towards the inside of the
clutch-differential crankcase.
DISMOUNTING
In case of the bearing ( 7), its cage C must
be oriented towards the opposite side of the
differential crown. In order to press this bearing into the clutch
crankcase, the C.V. 1059 device is used,
which is pressing on the outer ring of the bear-
ing.
When remounting the other bearing ( 10),
its cage C must be oriented towards the op-
posite side of the differential crown.
For pressing, the 65 mm diameter sleeve
of the C.V.1059 device is used, which is
pressing on the outer ring of the bearing
Remount the bearing maintaining safety.

Three drops of
LOCTITE FRENBLOC
are a pplied on the grooves of the fi xed pinion
for the 5 th gear, then this is m ounted by means
of the C.V. 1175 device on the secondary shaft.
Di smount the C.V. 1175 device and mount
the secondary shaft screw oiled with 3 drops of
LOCTITE FRENBLOC.
On the primary shaft remount the following
sequence :
- the support washers (with the larger side
towards the pinion )
- the bushing under the pinion;
- the free 5 th pinion equipped with its
synchroni ser ring ;
- the 5-th gear step hub equipped with its
spring after the hub grooves have been oiled with
LOCTITE FRENBLOC; - the fork together with the 5 th sliding
collar.
Engage the 1-st gear with the gear lever and
the 5 th ge ar by sliding the 5-th gear step fork
on its axle.
Apply 3 drops of LOCTITE FRENBLOC
on the primary shaft nut.
Mount the nut and the screw and tighten them
at the required moment: - primary shaft nut : 19 daNm
- secondary shaft screw : 7 daNm

The pusher adjustment shall be performed taking into consideration, the wear degree of the
rack and the pusher.

3. Pusher spring
4. Assembled threaded plug
When mounting distribute 23 + / - 5cmc

rack, the gear, the pusher and the spring, the
inner surface.
ADJUSTEMENT METHOD
The clearance adjustment of the pusher is performed by tightening the threaded plug at the
required moment of 1+/-0,2 daNm and unscrewing it ˘ round.
The moment for the gear rotation will be
about 0,15 daN.m (maximum accepted 0,25
daN .m ) on the whole length of the rack or
the rack gliding effort of 25 daN (maximum
accepted 40 daNm ) without rigid points.
Securing of the unscrewing of the threaded
plug is perform ed by the distort ion of t he
securing element of the assembled threaded
plug towards the casing in two antipodal
points.
