MAINTENANCE

Clutch System

Drive Belt Condition

Periodically check the condition and tension of the drive belt, and

always carry a spare. Inspect the belt for signs of excessive wear: frayed

edges, missing cogs, cracks and excessive looseness. Replace the belt if

any of these conditions exist. See Drive Belt Troubleshooting on page

112.

Always carry a spare drive belt for emergency use. Store the spare belt

on top of the electrical box, which is mounted to the clutch cover.

For improved drive-away during extremely cold temperatures, remove

the belt and warm it to room temperature. Reinstall it before starting the

snowmobile.

Drive Belt Deflection

Measure belt deflection with both

clutches at rest and in their full

neutral position.

Place a straight edge (1) on the

belt and apply downward pressure

while measuring at point 2. This

measurement should be 1 1/4

inches (3.2 cm).

Drive Belt Adjustment

1. Install the L-wrench into the open threaded hole in the outer sheave

of the clutch (see page 88). Turn the wrench clockwise slightly to

remove pressure from the sheaves.

2. Loosen the 7/16-inch jam nut on the belt width adjuster.

3. Using a 1/8-inch Allen wrench, turn the set screw inward

(clockwise) to increase the distance between the sheaves or outward

(counterclockwise) to decrease the distance.

4. Tighten the jam nut. Remove the L-wrench and store it in the tool

kit.
