MAINTENANCE AND LUBRICATION
Drive Chain
Polaris ATV drive chains are equipped with o-ring-sealed, permanently
greased pins and rollers. However, the outer surfaces of the roller must
be lubricated.
Always inspect the drive chain prior to operating the vehicle. Check for
damaged or missing o-rings or damaged rollers. Also check for 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. See page 100 for the part numbers of
Polaris products.
CAUTION
Washing the drive chain with a high pressure washer or gasoline
can cause damage to the o-rings, causing premature wear and
drive chain failure. Don’t use a high pressure washer or gasoline
to clean the drive chain.
