Belt dimensions are given in nominal dimensions. There is
a +/- variance for all critical dimensions. Clutch set up must
be inspected when a new belt is installed.
The drive belt is an important component of the converter
system. In order to achieve maximum efficiency from the
converter, drive belt tension (deflection), clutch offset, and
alignment must be adjusted properly.
The belt cord line should be flush with, or slightly above,
the outer circumference of the driven clutch sheaves. The
belt will seat itself in the driven clutch during the break-in
period. Adjust the belt ride out after the break-in period by
re-adjusting belt deflection.
The break-in period for a new drive belt is 30 miles. During
this time, vary the throttle position under 50% and limit full
throttle use.
New drive belts that feature a sanded finish should be first
washed with warm, soapy water and allowed to air dry
prior to use.
Always take time to warm up the belt and driveline prior to
operating the snowmobile. Free track and skis from the
ground before engaging throttle.

Belt Inspection

1. Measure the belt width and replace it if it is worn
severely. Generally a belt should be replaced if the
clutches can no longer be adjusted to provide the
proper belt deflection.
• Project the side profiles and measure from corner
to corner.
• Place a straight edge on each side of the drive belt
and measure the distance where the straight
edges intersect at the top.
2. Inspect the belt for loose cords, missing cogs, cracks,
abrasions, thin spots or excessive wear spots.
Replace if necessary.
3. Inspect the belt for hour glassing (extreme circular
wear in at least one spot and on both sides of the belt).
Hour glassing occurs when the drive train does not
move and the drive clutch engages the belt.
