Suspension - Yamaha SXV4NP Operator's Manual

3. After proper track alignment is
obtained, tighten the idler wheel axle
cap screw to 4.7 kg-m (34 ft-lb); then
tighten the adjusting bolts securely
against the axle.
! 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.
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.
The springs influence the load carrying
capability of the snowmobile and should
be adjusted for the weight and riding
preference of the operator.
FOX Shocks
If service work is needed on any FOX
shocks, the shock will have to be removed
and sent to FOX or any FOX distributor
for any service work. For FOX shock
information, visit www.ridefox.com.
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 Snowmo-
bile dealer for this service. If not under
warranty, this service is at the discretion
and expense of the snowmobile owner.
Adjusting Front (Ski)
Shock Springs
The front (ski) shock springs are individu-
ally 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 preload adjust-
ment is accomplished by loosening the
adjuster nut locking collar (B) from the
adjuster nut (A) and using the Spring
Adjuster Tool, rotating the adjuster nut in
whichever direction is desired. Tighten
the locking collar against the adjuster
nut.
