The letters AD - AS, printed in the back of torsion
bars, indicate respectively the right bar and the left
one.

Moreover the splined part has a double tooth (1) which, at
the reassembly, must correspond to the double spline (2) of
the upper lever.

With the tool No. 99357144 (1) fasten the ring nut (3,
Figure 50) to the prescribed torque.

Refit the wheels, mount the nut guard and screw on the fixing
nuts; lower the vehicle, removing the stands..

Following the order shown in the figure, tighten the fixing
nuts to the required torque.

Then tighten the torsion bar fixing nuts to the required
torque and mount the safety split pins on them.

Tighten the nuts for the screws securing the top and bottom
tie rods to their respective levers to the required torque.

Fit the stabilizer bar (1) back onto the bottom screw stays (2)
with the clamps (3), taking care that the screws (4) go into
the slots in the stabilizer bar.
Complete fitting the suspension back on by mounting the
shock absorber.

Lubricate the grooved portion of the torsion bar (3).
Assemble the torsion bar (3) and the support (1) so that the
splines (2) of the toothed bush and of the torsion bar coincide.
Fix the support (1) to the chassis tightening the fastening
screw nuts to the prescribed torque.

If the value is different, act on the adjusting screw (1) as much
as you need it, but remember that, before acting on the
screw, it is necessary, to lift the vehicle with the hydraulic jack,
so that the wheels are lifted from the ground. This is
necessary if you do not want to damage the screw.

Once the vehicle has reached the right position, lock the
screw with the lock nut (2).

TORSION BAR PRE-LOADING CONTROL DIAGRAM

H = mm, distance from ground of the side frame upper

thread, measured as near as possible the suspension

connecting area

RSC = mm, loaded wheel radius

Ensure that the wheel pressure complies with the prescribed
one and check, with the suitable gauge, that the thread depth
of tyres is more or less the same on both wheels.
Measure on both sides of the vehicle, the distance from
ground (H) of the side frame upper thread, measured as near
as possible the suspension connecting area.
The height H must correspond to the value given in the table
below.
