DRIVE CHAIN
Carefully read p. 60 (MAINTENANCE).
The vehicle is equipped with an endless
chain, in which a ring link joint is not used.
!
CAUTION
An excessive slackening of the chain
may cause noise or make the chain
rattle, with consequent wear of the shoe
and of the chain guide plate.
Periodically check the slack and adjust
i t i f n e c e s s a r y , s e e p . 8 2
(ADJUSTMENT).
To change the chain, contact an
aprilia
Official Dealer, who will ensure you
prompt and accurate servicing.
Incorrect maintenance may cause the
untimely wear of the chain and/or
damages to the pinion and/or the
crown.
NOTE
Perform the maintenance
operations with doubled frequency if the
vehicle is used in rainy or dusty areas, on
uneven surfaces or on racetracks.
CHECKING THE SLACK
To check the slack, proceed as follows:
◆
Stop the engine.
◆
Position the vehicle on the stand, see p.
58 (POSITIONING THE VEHICLE ON
THE STAND).
◆
Position the shifting lever in neutral.
◆
Make sure that the vertical oscillation, in
an intermediate point between pinion
and crown in the lower part of the chain,
is about
15 mm
.
◆
Move the vehicle forwards, or turn the
wheel, in order to be able to check the
vertical oscillation of the chain even
when the wheel turns; the slack must be
constant in all the rotation phases of the
wheel.
!
CAUTION
If in some positions the slack is higher
than in others, this means that there are
crushed or seized links; in this case,
contact an
aprilia
Official Dealer. To
prevent the risk of seizures, lubricate
