5. If the idler wheels are not centered,
an adjustment is necessary.
NOTE: There is no track alignment
on M models.
Adjusting Track Alignment
1. On the side of the track which has
the inner track drive lugs closer to
the rear idler wheel, loosen the idler
wheel axle cap screw; then rotate the
adjusting bolt clockwise 1 to 1-1/2
turns.
2. Check track alignment and continue
adjustment until proper alignment is
obtained.
NOTE: Make sure correct track
tension is maintained after adjusting
track alignment.
3. After proper track alignment is
obtained, tighten the idler wheel axle
cap screw to 34 ft-lb (46.2 N-m); then
tighten the adjusting bolts securely
against the axle.
4. Field test the track under actual con-
ditions.
5. After the field test, check the align-
ment of the track. If additional adjust-
ment is necessary, repeat Adjusting
Track Alignment procedure.
Suspension
The suspension should be adjusted for
the operational needs and riding prefer-
ence of the operator.
On models with rear suspension springs,
the springs influence the load carrying
capability of the snowmobile and should
be adjusted for the weight and riding
preference of the operator.
Adjusting Rear Spring
Preload
ZR/LT
Proper adjustment of rear spring preload
is necessary to get the most desirable
ride. The chart is designed to help in set-
ting up rear spring preload; however, rid-
ing style is the single greatest factor in
determining rear spring requirements.
NOTE: These cam position set-
tings are suggestions only. Personal
riding style will greatly influence
cam position settings. Spend time to
determine setting preferences.
Rear spring preload adjustment is accom-
plished by rotating the adjusting cams.
Position 3 provides the stiffest ride, and
position 1 is for the light driver or slow-
speed trail riding. Position 2 is for the
average operator under normal conditions.
Always rotate the cam from the lighter
position to the heavier position.

Articulating Skid Frame
(LT)
The rear articulating portion of the skid
frame has two skid frame blocks which
allow the skid frame to be locked or artic-
ulate.
! WARNING
Always make sure the adjusting bolts
are snug against the axle and the
idler wheel cap screws are tightened
to specifications. Failure to do so
could cause 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.
