installed correctly.
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. Periodic checks (at least
once a month under normal usage) of two
drive belt specifications are essential.
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 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 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.
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 (5000/7000)
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.
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.
