Track Alignment - Arctic Cat 120 Sno Pro Operator's Manual

3. If the deflection (distance between
the bottom of the wear strip and
the inside of the track) exceeds
specifications, tighten the adjust-
ing bolts to take up excessive slack
in the track.
4. If the distance between the bottom
of the wear strip and the inside
surface of the track is less than
specified, 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.
! 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
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. Arc-
tic 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 adjust-
ing track alignment.
injury could result if contact 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 snow-
mobile 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 revolu-
tions. SHUT ENGINE OFF.
 NOTE: Allow the track to coast to
a stop. DO NOT apply the brake
because it could produce an inac-
curate 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.
