Polaris is an American company, founded in 1954, that manufactures all-terrain vehicles, motorcycles and small neighborhood vehicles such as golf carts. Polaris introduced its first ATV in 1984. If you own a Polaris ATV, tightening the chain should be part of your regular maintenance schedule. Over time, the chain will stretch and become loose. This can cause damage to your vehicle if the chain were to fall off during use.
Park your ATV on level ground and shut off the engine. Raise the rear end with a tire jack so you can access the chain in the back of your ATV.
Loosen the two clamp bolts on each side at the back of the ATV. Insert a drift into the hole of the bearing housing.
Turn the bearing housing downward --- the chain should begin to be taut. Tighten the chain until it has about ¼ to 1/2 inch of play.
Tighten the two rear swing arm clamp bolts to pull the rear axle backward. Lower the ATV to the ground.
