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 O-Ring Chain Lubricant (PN
2871079).
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.
SPROCKET INSPECTION
Inspect the sprocket for worn, broken or bent teeth.
To check for wear, pull outward on the chain as shown. Re-
place sprocket if chain movement exceeds 1/4
s
(.6 cm).
DRIVE CHAIN INSPECTION
The chain must be replaced when it reaches 3% elonga-
tion.
1. Stretch the chain tightly in a straight line.
2. Measure a length of twenty pitches (pins) from pin
center to pin center, and compare to the specification.
Replace the chain if the length exceeds the wear limit.
3. When replacing or reinstalling drive chain, install the
closed end of the splice link clip as shown, with the
closed end leading in forward operation.
