REAR SUSPENSION, SHOCKS AND TRACK 12 - 10
After removing the parts, always lay them out in the order in
which they were dismantled.
l
NOTICE:
In general, it is recommended that the lock nut from the shock
absorber rod be replaced after the absorber has been
reassembled 4 times to ensure adequate locking friction.
l
NOTICE:
If it is necessary to re-calibrate the valves, it is absolutely
essential to identify the order in which the shims are stacked
(the number of shims and their thickness). The casing of the
ring seal does not need to be removed if it is only an operation
of re-calibration.
The shims can be measured using a sliding caliper or a
micrometer.
The shock absorber rod is plated. It must be inspected in order
to detect any visible marks of wear on the surface.
If there is a leak in the ring seal, it will be necessary to measure
the camber of the rod which must not exceed 0.025 mm (.001
in).
Once the new shims or the replacement shims have been
selected, reassemble everything by carrying out, in reverse
order, the same operations as for dismantling. Tighten the piston
nut between 11 and 13 N-m (1.1 and 1.3 kg-m, 8 and 9.5 lbf-ft)
t t
CAUTION
The nut for the rod of the shock absorber can only be
used 4 times before it is replaced. Use only an original
part to replace it; do not substitute any other kind of part
for it.
Make sure that the number of washers between the nut of the
shock absorber rod and the lock nut leave a sufficient number of
threads for the nut of the shock absorber rod.
Install the lock nut with the rounded part facing down.
l
NOTICE:
The stack of rebound shims must not touch the threads of the
rod. The washer(s) under the nut on the rod prevent the nut
from going to the end of the shoulder of the shock absorber rod.
