REAR BEARING ELEMENTS
CHARACTERISTICS
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 F 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 bearing, sealed and pre-set.

Check and adjust the hand brake cable.
Adjust the clearance at the limiter operating rod (see chapter 37- Brake limiter
adjustment).
REMOUNTING
Before remounting, grease with grease the attachment screws of the rear axle shock
absorber bottom and the chassis, consequently, the connecting screws rear axle-chassis.
Line up the arms bearings right to the chassis supports, mounting them without tighten-
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 clearance of the bearing using a dial gauge and the
support RO541A.
Note
The maximum allowed axle clearance of the bearing is 0.05mm.
Mount the rear wheels, lower the vehicle on the ground.
Refill with fluid the brake assembly.
Purge the braking system.
