8. Remove the reservoir cover and
remove the remaining fluid; then fill
the reservoir with fresh fluid and
install the cover.
9. Pump the brake lever to ensure cor-
rect positioning of the brake pads;
then release.
10. Remove the reservoir cover and fill
the reservoir to the proper level with
fresh brake fluid; then install the
cover.
NOTE: When new brake pads are
installed, a “burnishing” process is
required. Drive the snowmobile
slowly and compress the brake lever
several times until the pads just start
to warm up; then allow them to cool
down. This procedure stabilizes the
pad material and extends the life of
the pads.
Drive Belt
The drive belt transfers power from the
drive clutch to the driven pulley. 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.
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 specifi-
cations 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 pre-
mature 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 temper-
ature, 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 will allow the drive belt
to gain its optimum flexibility and will
extend drive belt life.
Checking/Adjusting Drive
Belt Deflection
0743-319
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 fit.
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.).
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.
