Power train support
Attach a parts support under t he power
train support and dismount: - connection screw anti-roll connecting
rod- steering box crossbar support a nd tilt
over the anti-roll connecting rod downward.
- clamps attachment of the high pressure
duct of the power-assisted steering ( on the
right side); - clamps attachment of the low pressure
duct of the power-assisted steering (on t he left
side);
- attachment screws of the bellows-bearing
GI joint assembly, left tra nsmission on the
gearbox; - lower attachment of the cooling radiator,
on both sides;
-lower a ttachment scre ws of the front
s hock absorbers, both on left and right side;
- steering knuckle arms;
- left transmission from the gearbox;
-r ight transmission from the gearbox.
Carefully lower the parts support towards
ground. Dismount the attachme nt screws of the power

Chara cteristics
The rear axle is composed of an axle having a “ U “ shaped torsion profile to which arms are
welded For the transversal stability and the resistance fatigue improvement of the cross- bar, the axle
is equipped with a Ö 21-mm diameter stabilizer bar. The bar is inserted by welding on both ends
in the axle side arms. The connection of the axle with the chassis is realized by elastic bushings of the spiral spring
and the double effect telescopic shock absorber. The drum and the hub constitute a common body, and are mounted on the steering knuckle
by means of a be-conical sealed bearing.

Adjust the hand brake cable.
Adjust the clearance at the limiter-operating rod (see chapter 37- Brake limiter adjust-
ment).
R EMOU NT I NG
Before remounting, lubricate with grease the a ttachment screws of the rear axle shock ab-
sorber bottom and the chassis, consequently , the connecting screws rear axle-chassis.
Line up the arms bearings right to the chassis supports, mounting the nuts with the screws
assembling the axle to the chassis, without tightening them to the moment,
Remount the springs.
Compress the axle so that rear springs are backed on the tray and mount the shock absorber
lower attachment screws.
Tighten to the prescribed moment the connecting screws.
Perform the dismounting operations in the reverse order.
Check the maximum allowed axial clearance of the bearing using a dial gauge and the support
R O541A.
REMARK :
The maximum allowed axle clearance of the bearing is 0.05mm.
Mount the rear wheels, lower the vehicle on the ground.
Tighten to the required moment, the rear wheels attachment screws.
Refill with fluid the brake circuit.
Purge the braking system.

Shock absorber upper attachment nut 1.35
R EMARK :
The shock absorbers are stored in
horizontal position. In these conditions, it is
possi bl e t ha t shoc k a bsorb e rs worki ng
vertically, to get depressed. Therefore, be fore mounting on the vehicle,
it is necessary to perform the shock absorbers
pressing, by alternatively shifting the shock
absorber rod (upwards and downwards), the
shock absorber being in vertical position.
