Further, check the following parts every
4687 mi (7500 km) and make sure that
chain, front and rear sprockets do not
show:
– damaged rollers;
– loose pins;
– dry, rusty, crushed or seized links;
– excessive wear;
– lacking O-rings;
– front or rear sprocket teeth excessively
worn or damaged.
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

CLEANING AND LUBRICATION
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.
◆
Wash the chain with diesel oil or
kerosene. If it tends to rust quickly,
intensify the maintenance intervals.
Lubricate the chain every 625 mi (1000
km) or whenever necessary.
◆
After washing the chain and letting it dry,
lubricate it with spray grease for chains
provided with sealing rings, see p. 144
(LUBRICANT CHART).
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
