Drive Chain - APRILIA RSV MILLE - 2002 Manual

DRIVE CHAIN

Carefully read p. 59 (MAINTENANCE).
The vehicle is equipped with an endless
chain, in which a ring link joint is not used.
An excessive slackening of the chain
may cause noise or make the chain ratt-
le, with consequent wear of the shoe
and of the chain guide plate.
Periodically check the slack and adjust it
if necessary, see p. 75 (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 dama-
ges to the pinion and/or the crown.
NOTE
Perform the maintenance opera-
tions 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 25 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 con-
stant in all the rotation phases of the whe-
el.
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
the chain frequently, see p. 76 (CLEA-
NING AND LUBRICATION).
If the slack is uniform, but higher or lower
than 25 mm, adjust it, see p. 75 (ADJUST-
MENT).
ADJUSTMENT
NOTE
To adjust the chain it is necessa-
ry to use the appropriate rear support
stand %.
If after the check it is necessary to adjust
the chain tension, proceed as follows:
◆
Position the vehicle on the appropriate
rear support stand, see p. 67 (POSITIO-
NING THE VEHICLE ON THE REAR
SUPPORT STAND %).
◆
Loosen the nut (1) completely.
NOTE
For the wheel centering fixed re-
ference marks (2-3) are provided, which
can be seen inside the chain tightener
seats on the rear fork arms, before the
wheel pin.
◆
Loosen the two lock nuts (4).
◆
Act on the adjusters (5) and adjust the
chain slack, making sure that the refe-
rence marks (2-3) are correctly positio-
ned on both sides of the vehicle.
