SETTINGS AND ADJUSTMENTS
Lubricating the chain
Lubricate the chain following these instructions.
: Never use grease to lubricate the chain. Grease helps to accumulate dust
and mud, which act as abrasive and hepl to rapidly wear out the chain, the
sprocket, and the crown.
Disassembling and cleaning
When particularly dirty, remove and clean the chain before lubrication. Work as
follows:
- set a stand or a block under the engine and see that the rear wheel is lifted from
the ground;
- remove: screws (1), transmission sprocket guard (2), clip (3), master link (4) and
transmission chain (5). To reassemble, reverse the above procedure.
Check that the chain is neither worn out nor damaged. If the rollers or the links are
damaged, replace the chain by following the instructions given in the Periodical
Maintenance Table. Check that neither the sprocket nor the crown are damaged.
Wash and clean the chain as described hereunder.
Washing the chain without OR (TC)
Wash using either oil or diesel oil. When using gasoline or tricloroetilene, clean
and lubricate the chain to prevent oxidation.
Washing the chain with OR (TXC-TE-SMR)
Wash using oil, diesel oil, or paraffin oil. Never use gasoline, tricloroetilene, or
solvents, as the OR may suffer damages. Use instead special sprays for chains
with OR.
Lubricating the chain without OR (TC)
First dry, then plunge the chain in a bisulphide molybdenum lubricant, or in high
viscosity engine oil. Warm up the oil before use.
Lubricating the chain with OR (TXC-TE-SMR)
Lubricate all metallic and rubber (OR) elements using a brush, and use engine oil
with SAE 80-90 viscosity for the internal and external parts.
If the chain has been cut, reassemble using a joint. Assemble the joint spring (a)
by turning the closed side to the chain direction of rotation as shown in figure.
: Even if all the joints are reusable when in good conditions, for safety
purposes we advise using new joints when reassembling the chain.
Accurately adjust the chain as shown on page D.21.
: The chain oil has NEVER to get in contact with the tires or the rear brake
disk.
: Chain tension rollers, chain driving roller, chain guide, chain runner
Check the wear of the above mentioned elements and replace them when
necessary.
: Check the chain guide alignement, and remember that a bent element can
cause a rapid wear of the chain. In this case, a chain fleeting from the sprocket
may ensue.
