MAINTENANCE
Before starting the snowmobile in
extremely cold temperatures, the drive
belt should be removed and warmed
up to room temperature. Once the
drive belt is at room temperature,
install the drive belt.
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 flexibil-
ity and will extend drive belt life.
NOTE: On the ACT roller driven
pulley, adding shim washers will
decrease belt deflection and
removing 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 of the ACT
drive models, 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
snowmobile owner.
Removing Drive Belt

2. Set the brake lever lock.
3. Open the hood; then open the belt
guard.
4. Grasp the driven pulley roller
plate and push against it while
rotating it clockwise.

hold the roller plate, pull up on
drive belt, and roll the belt over
the stationary sheave until it is
free of the driven pulley. Slowly
release the roller plate.

6. When the belt is free of driven
pulley, remove the belt from the
drive clutch.
Installing Drive Belt
(Standard Driven
Pulley)
1. Place the belt (so the part number
can be read) between the sheaves
of the drive clutch.
2. Grasp the driven pulley roller
plate and push against it while
rotating it clockwise.
3. When the sheaves are fully apart,
hold the roller plate, roll the belt
over the stationary sheave, and
slowly release the roller plate.
! 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.
