Drive Belt
The drive belt transfers power from the
drive clutch to the driven clutch. If the
belt is worn, cracked, or stretched, maxi-
mum power will not be transmitted and
the belt could also fail and therefore must
be replaced.
The drive clutch is equipped with an idler
bearing which requires no belt deflection
screw in the driven clutch. This set up
with auto adjust the belt deflection.
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. 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 specifications
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 premature 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 tem-
perature, install the drive belt.
Also, new drive belts have a break-in period
of 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.
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.
Removing
1. Set the brake lever lock; then
remove the left-side access panel.
2. Thread Removal/Installation Tool
clockwise into the driven clutch
until the movable sheave opens far
enough to remove the drive belt.
SNO-778
3. When the sheaves are fully apart,
pull up on drive belt and roll belt
over stationary sheave until it is free
of the driven clutch.
4. When the belt is free of driven
clutch, remove the belt from the
drive clutch.
Installing
1. Place the belt (so the part number
can be read) between the sheaves of
the drive clutch.
2. With the sheaves fully apart, roll the
belt over the stationary sheave.
3. With the drive belt properly posi-
tioned in the drive clutch and driven
clutch, turn the belt tool counter-
clockwise and roll the belt back and
forth to allow the driven clutch
sheaves to fully close.
4. Install the left-side access panel.
5. Release the brake lever lock.
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.
