Suspension - Yamaha SR10RE Operator's Manual

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).
! 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.
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.
! 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 absorb-
ers 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 cyl-
inders in any way. Cylinder dam-
age 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.
 NOTE: On SE models with a rear
arm float shock, this adjustment is
achieved by increasingly or decreas-
ing the air pressure in the rear arm
air shock absorber.
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 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.
