Also, drive belts have a break-in period
of approximately 20 miles. After
installing a new drive belt, drive the
snowmobile for 20 miles at 1/2 throttle
or less. This will allow the drive belt to
gain its optimum flexibility and will
extend drive belt life.
Checking/Adjusting
Drive Belt Deflection
The drive belt must have the proper fit
in the drive clutch and driven pulley.
To check for proper drive belt fit, use
the following procedure.
1. Place a straightedge on the top of
the drive belt. The straightedge
should reach from the drive clutch
to the top of the driven pulley.
 NOTE: Make sure the drive belt
is all the way out in the driven pul-
ley before checking drive belt fit.
2. Using a
between the drive clutch and
driven pulley, push down on the
drive belt just enough to remove
all slack and note the amount of
deflection. The deflection should
be within the range of 28.5-31.8
mm (1 1/8-1 1/4 in.).
3. To correct drive belt deflection,
remove the sheave adjuster from
the pulley, remove or add shim
washers to the adjuster, and install
the adjuster.

 NOTE: Adding shim washers will
decrease belt deflection and remov-
ing shim washers will increase belt
deflection. Available shim washers
from Arctic Cat are p/n 0648-714
(0.090 in.) - one included in the tool
kit, p/n 0648-715 (0.030 in.), and p/n
0648-716 (0.060 in.).
 NOTE: Removing/adding shim
