Adjusting Track Tension
1. Loosen the idler wheel cap screws.
2. Loosen the rear idler wheel adjust-
ing bolt jam nuts.
NOTE: To ensure proper track ten-
sion adjustment, perform all adjust-
ments
on
both
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 idler wheel cap screws securely.
NOTE: Since track tension and
track
alignment
always check both even if only one
adjustment seems necessary.
! WARNING
If jam nuts are not tightened properly,
the adjusting bolts could loosen
causing
the
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.

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
! WARNING
Make sure the ignition key is in the
OFF position and the track is not
rotating before checking or adjusting
track
alignment.
could result if contact is made with a
rotating track.
the
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.
! WARNING
The tips of the skis must be posi-
tioned against a wall or similar object
for safety.
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 distance from the rear
idler wheels to the inner track drive
lugs is the same on both sides, no
adjustment is necessary.
