
NOTE: To ensure proper track ten-
sion adjustment, perform all adjust-
ments
on both sides of the
snowmobile.
3. If the deflection (distance between
the bottom of the wear strip and the
inside of the track) exceeds specifi-
cations, tighten the adjusting bolts to
take up excessive slack in the track.
4. If the distance between the bottom
of the wear strip and the inside sur-
face of the track is less than speci-
fied, loosen the adjusting bolts to
increase the slack in the track.
5. Check track alignment (see Track
Alignment section).
6. When proper track tension is
obtained, tighten the adjusting bolt
jam nuts against the axle housings.
7. Tighten the idler wheel cap screws
securely.

NOTE: Since track tension and
track alignment are interrelated,
always check both even if only one
adjustment seems necessary.
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.
! WARNING
If jam nuts are not tightened prop-
erly, 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.
! 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 for safety.
