ADJUSTING THE CHAINS
WARNING
q
The adjustment must be carried out with the machine
parked on a firm, level and not slippery surface.
q
Before carrying out the adjustment, take all the neces-
sary safety precautions.
CAUTION
q
When adjusting the hub-holding plate, do not loosen the
fastening nuts by giving them more than 2 turns, in or-
der to prevent any oil leakage.
If the wheel slack exceeds 6 mm, carry out the following ope-
rations:
1 - Remove the wheel nuts using a 24 mm hexagon spanner.
2 - Position the adjusting screw (3) included in the supply on
the appropriate hole and make it rest against the hub-hol-
ding plate (1). Use a 17 mm hexagon spanner.
3 - Loosen the nuts (2) of the hub-holding plate (1), giving
them max. 2 turns. Use a 22 mm hexagon spanner.
4 - Adjust the screw (3), moving the hub-holding plate 1 or 2
mm forwards.
5 - Fasten at least 3 diametrically opposite nuts (2) of the
hub-holding plate.
6 - Install the wheel and check the wheel slack.
If the wheel slack value is not included within the prescribed
value range, repeat the operations described above.
If, on the contrary, the wheel slack value is included within this
range, proceed as follows:
1 - Remove the wheel again.
2 - Tighten all the nuts (2) of the hub-holding plate (1) by ap-
plying the prescribed driving torque (see "4.4.1 STAN-
DARD DRIVING TORQUES").
3 - Remove the adjusting screw (3).
4 - Put back the wheel definitively, tightening the nuts with the
prescribed torque (see "4.4.2 SPECIFIC DRIVING TOR-
QUES").
Repeat this procedure also for the other wheels.
IMPORTANT
q
It is important to remember that each side of the final
transmission (right and left) is constituted by two chains
(front and rear) that transmit motion to the correspond-
ing wheels.
Each chain can be adjusted independently of the others.
