Track Alignment - Arctic Cat AC 120 2007 Operator's Manual

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 neces-
sary.
! WARNING
If jam nuts are not tightened
properly, the adjusting
could loosen causing the track to
become extremely loose and,
under some operating condi-
tions, allow the idler wheels to
climb over the track lugs forcing
the track against the tunnel caus-
ing the track to "lock." If a track
"locks" during operation, severe
personal 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. Per-
sonal injury could result if con-
tact is made with a rotating track.
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
bolts
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 revolu-
tions. SHUT ENGINE OFF.
