REAR SUSPENSION WITH SINGLE-BLADE PARABOLIC LEAF SPRING

Check the threads of brackets which fasten the leaf
springs to the axle; if they are damaged, re-machine
the threads (operation 500412) or replace the
brackets.

Tighten the nuts to the prescribed driving torque.
Following the order shown in the figure.

After replacing the leaf springs and the hydraulic shock
absorbers, it is necessary to check the efficiency of the braking
control and, if necessary, carry out its adjustment (operation
796910. See Braking System Section).

To re-fit, carry out the removal operations in reverse, taking
the following precautions.

Assembling the leaf spring

Ensure that the leaf contact surfaces are perfectly smooth and
clean.
Before re-assembling the leaves, grease contact surfaces with
a little of CA IG Grease.
Re-assemble the pack as follows (see Figure 93):

- place the main leaf (1) with the end eyes in the end pin

of the 1st leaf (4);

- place the other leaves, included the one with the clip (5),

near the former ones, rest them on one side and align
them in the bench vice;

- insert through the central hole of the leaves, the central

pin (7), then lock the pack in the vice;

- insert the nut (2) on the central pin (7) and lock;

- close the two side retaining clamps (5) by folding the ends

back as shown in the figure.

Side clips (5) fastened with a rivet (6) to the leaf, can
be re-used, provided that they do not show signs of
breakage when they are re-bent to hold the pack. In
this case, it is necessary to replace them with new
ones to be fixed to the leaf with new rivets.

Place the leaf spring in the vice of the suitable bench, clamping
it near the central pin; remove the relevant nut and extract the
central coupling pin.

Unscrew the fastening nut (2) of the central pin (7) and
extract the pin. Open the pack side clips (5), lifting the two
ends that are bent on the main leaf. Open the vice and
disassemble the leaf spring.

In case other leaves are broken or yielded, replace the
whole leaf spring.

Checks

Carefully clean, with diesel oil or solvent, all
components; ensure that the bushes are firmly driven
in the spring eyes and shackles.
Check that the internal surface is not ovalized and that
the pins are not worn or strained, in case they are,
replace them.
