5. If the idler wheels are not centered
between the inner track drive lugs,
an adjustment is necessary.
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 adjust-
ing track alignment.
3. After proper track alignment is
obtained, tighten the idler wheel
axle cap screw to 34 ft-lb; 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.
The front shock springs determine the
amount of ski pressure and the reaction
of the front suspension to rough terrain.
The amount of ski pressure can also be
changed by adjusting the length of the
skid frame front arm limiter straps.
On standard models, the rear arm shock
absorber spring influences the load carry-
ing capability of the snowmobile and
should be adjusted for the weight and rid-
ing preference of the operator.
NOTE: On Sno Pro models with a
rear arm float shock, this adjustment
is achieved by increasingly or
decreasing the air pressure in the
rear arm air shock absorber.
Adjusting Front (Ski)
Shock Springs
The front (ski) shock springs are individ-
ually adjustable for the terrain conditions
and driving style of the operator. The
spring adjuster nut has been set at the fac-
tory so the correct amount of threads are
exposed between the adjuster nut and the
threaded shock body as an initial setting.
Additional ski pressure can be obtained
by tightening the spring tension; ski pres-
sure can be decreased by relaxing spring
tension.
NOTE: Equal adjustments should
be maintained on both sides of the
snowmobile.
Front (ski) shock spring pre-load adjust-
ment is accomplished by loosening the
adjuster nut locking collar (B) from the
adjuster nut (A) and using the Spring
Adjuster Tool from the tool kit, rotating
the adjuster nut in whichever direction is
desired. Tighten the locking collar
against the adjuster nut.
! 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.
