- the wheel
- the two lower a ttachment screws of
the shock absorber leg (1 ).
- the two upper a ttachment screws of
the shock absorber on the carriage body (2).
T ake out the assembly spring – shock
absorber, by pressing on the lower arm in
order to avoid the shock absorber came in
contact with the transmission bellows.
SEPARATE SPRING 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.

Before remounting, grease with grease the attachment screws of the rear axle shock
absorber bottom and the chassis, consequently, the connecting screws rear a xle-c hassis. Line up the arm s beari ngs right to t he c hassis supports, mounting them without t ighten-
ing at the moment, the nuts with the screws, assembling the axle to the chassis.
Remount the springs.
Compress the axle so that rear springs bear on the tray and set back the shock absorber
inner attachment screws. Tighten at the prescribed moment the connecting screws.
Perform the dismounting operations in the reverse order.
Check the maximum allowed axial cleara nce of the bearing using a dial gauge and the
s upport RO541A.
Note
The maximum allowed axle clearance of the bearing is 0.05mm.
Mount the rear wheels, lower t he vehicle on the ground.
