Chain Tensioner - Polaris 120 Indy Owner's Manual

Maintenance

Chain Tensioner

Inspect the chain. Proper deflection is one inch (25 mm). Adjust the
chain if deflection is incorrect.
1. Loosen the nut on the chain tensioner.
2. Raise the tensioner until the correct deflection is attained.
3. Tighten the nut to 15-18 ft. lbs. (20-24 Nm).
TIP: When the chain has stretched to within 1/8" (3 mm) of the muffler mount
bracket on the chassis, replace the chain. Inspect the sprockets as they
also wear and often need replacement when the chain is replaced.
