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
deflection should be within the
range of 28.5-31.8 mm (1 1/8-1 1/4
in.).
3. To correct drive belt deflection,
remove the sheave adjuster from the
pulley, remove or add shim washers
to the adjuster, and install the
adjuster.
NOTE: Adding shim washers will
decrease belt deflection and remov-
ing 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, 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 snow-
mobile owner.

1. Turn ignition key to the OFF posi-
tion and wait for all moving parts to
stop.
2. Set the brake lever lock.
3. Open the left-side access panel; then
remove the belt guard.
4. Remove the cap screw, lock washer,
washer, and sheave adjuster from the
end of the driven pulley.

O-ring are not removed from the
adjuster.

5. Remove the cap screw (w/lock
washer and washer) from the
adjuster, remove the washer and
lock washer from the cap screw, turn
the adjuster around (reverse it), and

belt removed. Excessive revving of
the engine could result in serious
engine damage and drive clutch fail-
ure.
