Carry out the operations described for removal in reverse
order, but you must take the following precautions:
- fit the top flexible plugs (2) in the cross member (1) at
the position found during disassembly;
- fit the flexible plugs (4) onto the ends of the new leaf
spring (3);
- fit the leaf spring (3) into the cross member and
support it with a hydraulic lift;
- with two lifts arranged under the stub axles, lift them
together, checking that the flexible plugs (4) of the leaf
spring (3) get correctly positioned in the honeycomb
of the bottom suspension arms (5 and 8) and the
centre line (
⇒) of the leaf spring is aligned with the
central holes (
⇒) della traversa (1), of the cross
member (1), max. error
±2 mm;
- then complete refitting by tightening the screws or
nuts to the required torque;
- position the bottom flexible plugs (6) on the cover (7)
at the position found during disassembly;
- mount the cover (7) and tighten the screws and nuts
to the required torque.
!
The nylon self-locking nuts must be replaced with
new ones every time they are taken down.
!
For axle 5817 tighten the nut (24) (Figure 23) fixing
the link rod to a torque of 44
± 9 Nm.
Refitting
To block rotation of the pins of the swivel heads
(9 - 10), insert a suitable Allen wrench into the
hexagon sunk in it.

ASSEMBLY DRAWING OF FRONT TORSION BAR SUSPENSION
The hydraulic shock absorbers are the double-acting
telescopic type.
The side tie rods are mounted at the front to the chassis
frame mounting by means of adjustable link pins, and at the
rear to the transverse levers.
The purpose of the stabilizer bar, mounted on the bottom
reaction screw stays, is to maintain the parallelism between
the axis of the wheels and the chassis frame, cancelling any
load unbalance on the wheels mounted on the same axle.
The purpose of the rubber pads fixed on the top mounting
of the shock absorbers is to limit the upward movement of
the suspension.
(Axle 5819 - vehicles 35C - 40C - 45C - 50C)
Description
The torsion bar suspension is composed of:
- two bottom suspension arms.
- two top suspension arms;
- two longitudinal torsion bars;
- two hydraulic shock absorbers;
- two bottom reaction tie rods;
- two top reaction tie rods;
- a stabilizer bar;
- two rubber pads.
The longitudinal torsion bars are anchored at the front to the
top suspension arms and at the rear to a mounting secured
to the chassis frame.
