MAINTENANCE
Drive Chain Inspection and Adjustment
Polaris ATV drive chains are equipped with O-ring sealed permanently greased
pins and rollers. However, it is still necessary to lubricate the outer surfaces of the
roller.
CAUTION: Never wash the chain with a high pressure washer or gasoline. Dam-
age to the O-rings will result, causing premature wear and drive chain failure.
Always inspect the drive chain prior to operating the vehicle, checking for dam-
aged or missing O-rings, rollers and correct slack adjustment. Maintain the stone
guard to rear sprocket clearance at 1/8" (.3 cm).
Regularly lubricate the drive chain with SAE 80-90 lube or an approved O-ring
chain spray lube.
