Track Alignment
Proper track alignment is obtained when
the rear idler wheels are equal distance
from the inner track drive lugs. Excessive
wear to the idler wheels, drive lugs, and
track will occur if the track is improperly
aligned. Arctic Cat recommends that the
track alignment be checked once a week
or whenever the track tension is adjusted.
Checking Track Alignment
1. Remove excess ice and snow buildup
from the track, track drive sprockets,
and the inside of the skid frame.
2. Position the tips of the skis against a
wall; then using a shielded safety
stand, raise the rear of the snowmo-
bile off the floor making sure the
track is free to rotate.
3. 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 inaccu-
rate alignment condition.
4. When the track stops rotating, check
the relationship of the rear idler
wheels and the inner track drive lugs.
If the rear idler wheels are centered
between the inner track drive lugs, no
adjustment is necessary.

5. If the idler wheels are not centered
between the inner track drive lugs,
an adjustment is necessary.
Adjusting Track Alignment
1. On the side of the track which has
the inner track drive lugs closer to
the rear idler wheel, loosen the
adjusting bolt jam nut; then rotate
the adjusting bolt clockwise 1 to 1 1/
2 turns.
NOTE: The rear axle cap screws
must also be loosened.
2. Check track alignment and continue
adjustment until proper alignment is
obtained.
NOTE: Make sure correct track
tension is maintained after adjust-
ing track alignment.
3. After proper track alignment is
obtained, tighten the adjusting bolt
jam nut against the axle housing.
4. Tighten the rear axle cap screws to
20 ft-lb.
5. Field test the track under actual con-
ditions.
6. After the field test, check the align-
ment of the track. If additional adjust-
ment is necessary, repeat Adjusting
Track Alignment procedure.
! WARNING
Make sure the ignition key is in the
OFF position and the track is not
rotating before checking or adjusting
track alignment. Personal injury
could result if contact is made with a
rotating track.
! WARNING
The tips of the skis must be posi-
tioned against a wall or similar object.
! WARNING
DO NOT stand behind the snowmo-
bile or near the rotating track. NEVER
run the track at high speed when the
track is suspended.
! WARNING
If jam nuts are not tightened properly,
the adjusting bolts could loosen
causing the track to become
extremely loose and, under some
operating conditions, allow the idler
wheels to climb over the track lugs
forcing the track against the tunnel
causing the track to “lock.” If a track
“locks” during operation, severe per-
sonal injury could result.
