MAINTENANCE
Clutch System
n 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
123.
For improved drive-away during extremely cold temperatures, remove
the belt and warm it to room temperature. Reinstall it before starting the
snowmobile.
n Drive Belt Deflection
Measure belt deflection with both
clutches at rest and in their full
neutral position.
Place a straight edge on the belt
and apply downward pressure
while measuring at point A. This
measurement should be 1 1/4"
(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 106). Turn the wrench clockwise slightly to
remove pressure from the sheaves.
2. Loosen the 7/16" jam nut on the belt width adjuster.
3. Using a 1/8" Allen wrench, adjust the threaded set screw as needed.
Tip: Turn the set screw in (clockwise) to increase the distance between the
sheaves and out (counterclockwise) to decrease the distance.
4. Tighten the jam nut.
