Driven Clutch - Arctic Cat 2014 SNO PRO 500 Operator's Manual

NOTE: Drive belts should be purchased 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 manu-
facturers may not be of the same specifications or
quality and, therefore, usage could result in poor
performance and premature belt failure.
CAUTION
Never run the engine with the drive belt removed.
Excessive revving of the engine could result in seri-
ous engine damage and drive clutch failure.
Before starting the snowmobile in extremely cold tem-
peratures, 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 approxi-
mately 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 will allow the drive
belt to gain its optimum flexibility and will extend
drive belt life.
Removing Drive Belt
1. Remove the tether switch cap and wait for all
moving parts to stop.
2. Set the brake lever lock.
3. Remove the hood; then remove the left-side access
panel.
4. Using Drive Belt Deflection Tool (p/n 0644-424),
thread the tool clockwise into the driven clutch
until the movable sheave opens far enough to
remove the drive belt.
5. 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.
6. When the belt is free of driven clutch, remove the
belt from the drive clutch.

Installing Drive Belt
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 positioned 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. After the belt is installed properly, install the left-
side access panel and the hood.
Never operate the snowmobile without the access
panel and hood in place.
5. Release the brake lever lock.
