1. Measure the outside circumference
of the drive belt. The belt should be
within the recommended range in
circumference (see appropriate spec-
ifications sheet).
2. Measure the outside width of the
drive belt. The belt should be within
the recommended range in width.
3. Check the belt for cracking, fraying,
etc.
If any of the specifications or conditions
are unsatisfactory, replace the drive belt.
NOTE: Drive belts should be pur-
chased from an authorized Arctic
Cat Snowmobile dealer, as Arctic Cat
drive belts are made to exact specifi-
cations and of quality material. Belts
made by other manufacturers may
not be of the same specifications or
quality and, therefore, usage could
result in poor performance and pre-
mature belt failure.
NOTE: Before starting the snowmo-
bile in extremely cold temperatures,
the drive belt should be removed and
warmed up to room temperature.
Once the drive belt is at room temper-
ature, install the drive belt.
Also, new drive belts have a break-in
period of approximately 25 miles. After
installing a new drive belt, drive the
snowmobile for 25 miles at 3/4 throttle or
less. By revving the engine up and down
(but not exceeding 60 mph), the exposed
cord on the side of a new belt will be
worn down. This allows the drive belt to
gain its optimum flexibility and will
extend drive belt life.
Checking/Adjusting Drive
Belt Deflection
0746-092
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 pulley
before checking drive belt deflection.
2. Using a stiff ruler centered 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 deflec-
tion 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
washers may be done by the snow-
mobile owner if qualified to do so. If
the owner does not feel qualified,
take the snowmobile to an autho-
rized Arctic Cat Snowmobile dealer
for this service. This service is at the
discretion and expense of the snow-
mobile owner.
CAUTION
Never run the engine with the drive
belt removed. Excessive revving of the
engine could result in serious engine
damage and drive clutch failure.
