DRIVE CHAIN AND
SPROCKET INSPECTION
Polaris ATV drive chains are equipped with O-ring
sealed permanently greased pins and rollers. The
sprockets and outer rollers require periodic
lubrication. Lubricate the chain with Polaris Chain
Lubricant ( PN 2872073 ).
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.
