MAINTENANCE AND LUBRICATION
Adjustments
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 141 for the part numbers of
Polaris-recommended products.
Cylinder Head/Cylinder Base Fastener - 2-Cycle
Have your dealer check the ATV cylinder head and cylinder base
fasteners for proper torque at the first service or after 25 hours.
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.
