CHECKING THE WEAR OF CHAIN,
PINION AND CROWN
Further, check the chain and sprockets
and make sure that they do not present:
– damaged rollers;
– loose pins;
– dry, rusty, crushed or seized links;
– excessive wear;
– lacking O rings;
– sprocket or teeth excessively worn or
damaged.
CAUTION
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).
Lubricate the chain frequently, espe-
cially if there are dry or rusty parts.
The crushed or seized links must be lu-
bricated and made work again.
If this is not possible, contact an
Official Dealer, who will provide for
changing the chain.
N
Finally, check the wear of the rear fork
protection shoe.

CLEANING AND LUBRICATION

CAUTION
The drive chain is provided with O rings
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.
N
Wash the chain with naphtha or kero-
sene. If it tends to rust quickly, intensify
the maintenance intervals.
Lubricate the chain every 1000 km (625
mi) or whenever necessary.
N
After washing the chain and letting it dry,
lubricate it with spray grease for chains
provided with sealing rings, see p. 103
(LUBRICANT CHART).
CAUTION
The lubricants for chains available on
the market can 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 cen-
trifugal force the lubricant would be
sprayed outwards and dirty the surround-
ing areas.
