MAINTENANCE
Drive Chain
Drive Chain and Sprocket Inspection
Inspect the drive chain for missing or damaged O-Rings, link plates, or rollers. Do not wash the chain with a high
pressure washer, gasoline or solvents; do not use a wire brush to clean the chain as damage to the O-Rings may
occur. Clean chain with hot soapy water and a soft bristled nylon brush.
Never allow battery acid to contact the drive chain. Periodically lubricate the chain with Polaris a-Ring Chain
Lubricant (PN 2871079).

The rear chain will change tension as the swingarm moves through the range of travel. Adjusting the chain at
the tightest point (swingarm pivot, output shaft sprocket, and rear axle are aligned in a straight line) will ensure
proper adjustment and prevent damage to the chain, sprockets, axle bearings and transmission bearings.
Drive Chain Inspection
Polaris ATV drive chains are equipped with a-ring sealed permanently greased pins and rollers. The sprockets
and outer rollers require periodic lubrication.
Always inspect the drive chain prior to operating the vehicle, checking for damaged or missing a-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 Polaris a-Ring Chain Lube or an approved O-ring chain spray lube.
