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.
Removing Drive Belt
NOTE: Changing a drive belt can
be done by the snowmobile owner if
qualified to do so. If the owner does
not feel qualified, take the snowmo-
bile to an authorized Arctic Cat
Snowmobile dealer for this service.
This service is at the discretion and
expense of the snowmobile owner.
1. Turn ignition key to the OFF posi-
tion and wait for all moving parts to
stop.
2. Set the brake lever lock.
3. Open the left-side access panel; then
remove the rear belt guard.
NOTE: On the 1100 cc models,
move and secure the rear belt guard
up and out of the way.
4. Remove the cap screw, lock washer,
washer, and sheave adjuster from the
end of the driven pulley; then
remove the sheave adjuster from the
cap screw.

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.
