CHECKING DRIVE BELT ALIGNMENT
1. Elevate the rear of the snowmobile on a shielded
safety stand high enough to raise the track off the
ground.
2. Start the engine and accelerate slightly. Use only
enough throttle to turn the track several revolutions.
Shut engine off.
NOTE: Allow the track to coast to a stop. Do not
apply the brake because it could produce an inaccurate
drive belt alignment condition.
3. Set the brake lever lock; then start the engine and
allow to idle. If the drive belt does not squeal with
the brake lever locked, the drive belt alignment is
correct.
4. If the drive belt squeals with the brake lever locked,
proceed to Adjusting Drive Belt Alignment.
ADJUSTING DRIVE BELT ALIGNMENT
1. Thread the Belt Removal/Installation Tool clockwise
into the driven clutch until the movable sheave opens
far enough to remove the drive belt. Remove the belt
and the tool.

2. Remove the cap screw and washer securing the
driven clutch to the driven shaft; then remove the stationary
sheave from the shaft.
3. To move the stationary sheave inward on the shaft,
remove alignment washers located on driven shaft.
4. To move the stationary sheave outward on the shaft,
add alignment washers to the driven shaft.
NOTE: Available shim washers from Arctic Cat are
p/n 0648-850 (0.090 in.) and (p/n 0648-849 (0.030 in.).
When adding or removing washers, the thickest
washer in the stack needs to be the most inward on
the shaft.
5. Arrange washers so drive belt does not squeal when
the brake lever is locked and the engine is at idle.
6. Shut the engine off and open the left-side access
panel; then using a feeler gauge make sure there is
approximately 0.010 mm between the stationary
sheave and the drive belt.

CAUTION
Make sure the drive belt is installed after the driven
clutch is completely installed and torqued to 60 ft-lb
(81.6 N-m). Failure to do this will cause damage to the
driven clutch.
! WARNING
The tips of the skis must be positioned against a wall or
similar object for safety.
! WARNING
DO NOT stand behind the snowmobile or near the rotating
track. NEVER run the track at high speed when the
track is suspended.
