Chain lubrication

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 help to rapidly wear out
the chain, the front and rear sprockets.

Disassembling and cleaning

When particularly dirty, remove and clean the chain before lubrication. Proceed
as follows:
- Set a stand or a block under the engine and see that the rear wheel is lifted
from the ground.
H06707
- Remove: screws (1), sprocket guard (2), clip (3), master link (4) and chain
(5). To reassemble, reverse the above procedure.
Make sure 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
Scheduled Maintenance Chart. Ensure that the sprockets are not damaged.
Wash and clean the chain as described hereunder.

Washing a chain without O-rings (CR)

Wash using petroleum or naphtha. If you use fuel or especially trichloroethylene,
dry and lubricate the chain to avoid oxidisation.

Washing the chain with OR (WR)

Wash using oil, diesel oil, or paraffin oil. Never use gasoline, tricloroetilene, or
2
solvents, as the OR may suffer damages.
Use instead special sprays for chains with OR.

Lubricating a chain without O-rings (CR)

H06708
After drying, dip the chain in Molybdenum Disulphide chain lubricant, if possible,
or in warm high-viscosity engine oil (if warmed up, oil will be more fluid).
As an alternative, you can use suitable spray lubricants

Lubricating the chain with OR (WR)

Lubricate all metallic and rubber (OR) elements using a brush, and use engine
4
oil with SAE 80-90 viscosity for the internal and external parts.
As an alternative, you can use suitable spray lubricants.
Assemble the master link clip (3) by setting the closed side facing the chain
direction of rotation, as shown in the figure.
H06706
The master link is the most critical safety part in the drive chain. Even
if the master links are reusable when in good conditions, for safety
purposes we advise using a new master link when reassembling
the chain.
Accurately adjust the chain as described in the relevant para-
graph.
