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
125.
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 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 (counter-clockwise) to decrease the distance.
4. Tighten the jam nut.
