The shock absorbers are stored in horizontal
position. In these conditions, it is possible that
s hock absorbe rs working vert ically, to get
depressed.
Therefore, before mounting on the vehicle, it
is necessary to perform the shock absorbers
pressing, by alternatively shifting the shock
absorber rod (upwards a nd downwards), the
shock absorber being in vertical position. S

Spring – shock absorber assembly
DISMOUNTING SPRING-SHO CK ABSORBER ASSEMBLY OF F THE VEHICLE
Loosen the front wheel attachment screws.
Lift the vehicle by means of a two-column
elevator. Dismo unt :
- the wheel;
-t he st eeri ng knuc kle attachment
screws (1) to the shock a bsorber leg;
- the two upper attachment screws (2 )
of the shock absorber on the carriage body.
Take out the spring – shock a bsorber
assembly, by pressing on the l ower arm, in
order to avoid the shock absorber getting in
contact with the transmission bellows.
SPRING DETACHMENT FROM SHOCK ABSORBER
Place t he shoc k absorbe r on t he shoc k
absorber support (4), of the base plate (3 ) of
the SU S 600 device.
Place the compression plate (7) on the filtering
block and position the rods grips (8) on the spring
lower last but one coil. Com p re ss t he sp ri ng by a l t e rna t i ve l y
tightening the nuts (9) till release it from the lower
plate of t he shock absorber.
Dismount the upper attachment nut of the
s hock absorbe r by means of the SUS 601
combined wrench.
Take out the spring
Place the spring on the SUS 600 device shaft
(2).
Place on the shaft the lock bushing (6), the spacer (5), and tighten the crank ( 1) to the
required moment till the lock bushing (6) comes into contact with the filtering block of the shock
absorber. Loosen alternatively t he nuts (9) and take out the plate (7) and the rods grips (8).
Release the spring by means of the crank (1) and detach from the shaft (2), the filtering block
of the shock absorber, the upper plate, a nd the spring.

REAR A XLES ELEMENTS

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.
