2. Elevate the snowmobile on a
shielded safety stand high enough to
use a spring scale.
3. At mid-point of the track (on the
bottom side), hook a spring scale
around a track clip; then pull down
on the scale to 9 kg (20 lb). Measure
the deflection (distance) between the
bottom of the wear strip and the
inside surface of the track clip. Mea-
surement should be 51 mm (2 in.).
Adjusting Track Tension
NOTE: To ensure proper track ten-
sion adjustment, perform all adjust-
ments
on
both
snowmobile.
1. Loosen the rear idler wheel adjust-
ing bolt jam nuts.
2. If the deflection (distance between
the bottom of the wear strip and the
inside surface of the track clip)
exceeds specifications, tighten the
adjusting bolts to take up excessive
slack in the track.
3. 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.
4. Check track alignment (see Track
Alignment sub-section in this section).
5. After
proper
obtained, tighten the adjusting bolt
jam nuts against the axle housings;
then tighten the rear axle cap screws
to 27.2 N-m (20 ft-lb).
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 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.
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.
! WARNING
DO NOT stand behind the snowmo-
is
bile or near the rotating track. NEVER
run the track at high speed when the
track is suspended.
3. Start the engine and accelerate
slightly. Use only enough throttle to
turn the track several revolutions.
SHUT ENGINE OFF.
