◆ Rotate the wheel manually, in such a
way as to check the vertical oscillation of
the chain even in other positions; the
slack must be const ant in all the whee l
rotation phases.
aCAUTION
If in some positions the slack is higher
than in others, this means that the re are
crushed or seized links; in this case,
contact an APRILIA Official Dealer. To
prevent the ri sk of seizures, lub ricate
the chain frequently, see p. 71 (CLEANING AND LUBRICATION).
If the clearance is slack is uniform, but
higher than 45 mm or lower than 35 mm,
adjust it, see p. 70 (ADJUSTMENT).
ADJUSTMENT
If after the check it is necessary to adjust
the chain tension, slacken the chain to increase the slack, tighten the chain to decrease it.
◆ Position the vehicle on the appropriate
rear support stand, see p. 69 (POSITIONING THE VEHICLE ON THE REAR
SUPPORT STAND m).
◆ Lock the rota tion o f the wheel pin (1) wit h
the appropriate key.
◆ Loosen the nut (2).

These reference marks can be seen by
looking inside t wo slots (5) (6) p ositioned
on the rear fork rods, before the wheel pin.
◆ Act on the left (3) an d ri ght ( 4) ad just ers
and adjust the chain slack, making sure,
on both sides of the vehicle, that the
same reference marks can be seen
when looking inside the slots (5) (6).
◆ Lock the rotation of the wheel pin (1) with
the appropriate key.
◆ Tighten the nut (2).
Wheel nut driving torque (1) (2): 100 Nm

◆ Check the chain slack, see p. 70
(CHECKING THE SLACK).
CHECKING THE DRIVING CHAIN, PINION AND SPROCKET WEAR
Further, check the chain and sprockets
and make sure that they do not present:
– damaged rollers;
– loose pins;
– dry, rusty, crushed or seized lin ks ;
– excessive wear;
– lacking O rings;
– sprocket or teeth excessively worn or
damaged.
aCAUTION
If the chain rollers are damaged, the
pins are loose and/or the O rings are
damaged or lacking, it is necessary to
change the whole chain unit (both
sprockets and chain).
aCAUTION
Lubricate the chain frequently, especially if there are dry or rusty parts.
The crushed or seized links must be lubricated and made work again.
If this is not possible, contact an APRIL
IA Official Dealer, who will provide for
changing the chain.
◆ Finally, check the wear of the rear fork
protection shoe.
CLEANING AND LUBRICATION
aCAUTION
The drive chain is provided with O ri ngs
among the links, in order to keep the
grease inside them.
Carry out the adjustment, lubrication,
cleaning and change of the chain with
great care.
Never wash the chain with water jets,
steam jets, high-pressure water jets and
highly inflammable solvents.
◆ Wash the chain with naphtha or kero-
sene. If it tends to rust quickly, intensify
the maintenance intervals.
Lubricate the chain every 500 km (312 mi)
or whenever necessary.
◆ After washing the chain and letting it dry,
lubricate it with spray grease for chains
provided with sealing rings, see p. 104
(LUBRICANT CHART).
aCAUTION
The lubricants for chains available on
the market may contain substances that
are dangerous for the rubber sealing
rings of the chain.
NOTE Do not use the vehicle soon after
lubricating the chain, since due to the centrifugal force the lubricant would be
sprayed outwards and dir ty the surrounding areas.
