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.
Gas Shocks
Each shock absorber should be visibly
checked weekly for fluid leakage, cracks
or breaks in the body, or a bent shaft. If
any one of these conditions is detected,
replacement is necessary. Take the snow-
mobile to an authorized Yamaha Snow-
mobile dealer for this service. If not under
warranty, this service is at the discretion
and expense of the snowmobile owner.
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 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 tor attempt
to open the cylinder assemblies.
• 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 service.
