ATV’s are demanding more and more from a battery. Yuasa knew that the ATV market was going to be big for batteries way back in the mid-1980’s when the new Maintenance-Free VRLA battery was developed for use in the Honda ATC.
How to Tighten the Chain on a Yamaha Warrior
Executive summary about the ATV market by Chris Gilliland
The chain requires little maintenance, mostly in the form of regular tension adjustments. X
Constant use slowly stretches the chain's links, causing the chain to loosen and eventually slip from the rear wheel's sprocket.
Things you'll need:
3. 14 mm socket
4. Socket wrench
5. Torque wrench
1. Place a jack below the Warrior's motor to lift the rear wheels at least one inch above the floor.
2. Grasp the lower portion of the chain at the midway point between the motor and the rear hub. Hold a ruler against the back of the chain and lift the chain until it is tight. Take note of the distance the chain has moved. Ideally, the chain should not move more than 1 1/2 inches. If the chain's slack allows more than 1 1/2 inches of travel, the chain is loose. Alternatively, if the chain has less than 1 3/16 inch of travel, it is too tight and requires loosening.
3. Loosen the bolts on the top and bottom of the rear hub with a 14 mm socket and a socket wrench. There are two bolts above the hub and two below the hub. Do not remove the bolts.
4. Slacken the lug nut on both of the chain tensioner's adjustment bolts, located below the rear hub, us ng a 12 mm wrench.
5. Turn the chain tensioner's adjustment bolts evenly with a 12 mm wrench to adjust the chain. Turn the bolts clockwise to tighten the chain or counterclockwise to loosen the chain.
6. Check the chain's travel again. Adjust the chain further, if the chain's tension is still less than 1 3/16 inches or greater than 1 1/2 inches. If the chain's tension is within the specified range, tighten each of the adjuster bolt's lock nuts against the tensioner body with the 12 mm wrench.
7. Tighten the rear hub's upper bolts to 72 foot-pounds and the lower bolts to 36 foot-pounds, using a 14 mm socket and a torque wrench. Remove the jack and lower the Yamaha Warrior's rear wheels to the floor.
An improperly aligned axle creates excessive wear and may cause the chain to break.
