Drive Chain Lubrication; Sprocket Inspection - Suzuki RM-z450 Owner's Service Manual

2-28 PERIODIC MAINTENANCE

DRIVE CHAIN LUBRICATION

• Remove the chain clip and joint from the drive chain and
remove the drive chain.
• Clean the drive chain with kerosine.
Do not use trichloroethylene, gasoline or any similar
solvent. These fluids will damage the O-ring seals.
Use only kerosine to clean the drive chain.
• After washing and drying the chain, oil it with a heavyweight
motor oil.
Do not use any oil sold commercially as "drive chain
oil". Such oil can damage the O-ring seals.
NOTE:
The standard drive chain is DID520MXV.
• Reassemble the drive chain.
NOTE:
Reassemble the drive chain clip so the slit end faces opposite
the direction of rotation.
Replace the joint, clip and O-ring seals with new ones.
• Adjust the drive chain slack.

SPROCKET INSPECTION

• Inspect the engine sprocket and rear sprocket for wear and
cracks. If any defects are found, replace the sprockets with a
new one.
NOTE:
When replacing a worn sprocket, it is likely that the drive chain
will need to be replaced as well.
