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 adjustments are
obtained and the adjusting bolts are
snug against the axle housings,
tighten the idler wheel axle cap
screws to 4.7 kg-m (34 ft-lb).
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 or shock air pres-
sure determines the amount of ski pres-
sure 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.
The rear arm shock absorber setting or
springs influences the load carrying capa-
bility of the snowmobile and should be
adjusted for the weight and riding prefer-
ence of the operator.
Adjusting Front Ski Shock Springs
The front ski shock springs are individually
adjustable for the terrain conditions and
driving style of the operator. The spring
adjuster nut has been set at the factory 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 pressure 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 tight-
ened 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
personal injury could result.

WARNING
Read and understand the following
information before handling shock
absorbers that contain highly pres-
surized nitrogen gas.
• Do not tamper with or attempt
to open the cylinder assem-
blies.
• Do not subject the shock
absorbers to an open flame or
other high heat source. This
may cause the unit to explode
due to excessive gas pressure.
• Do not deform or damage the
cylinders in any way. Cylinder
damage will result in poor
damping performance.
• Do not dispose of a damaged or
worn out shock absorber your-
self. Take the shock absorber to
a Yamaha dealer for any ser-
vice.
