SUSPENSION
IFS Adjustment and Ski Pressure
Increasing spring preload will
increase ski to ground pres-
sure. Decreasing spring pre-
load will decrease ski to ground
pressure under all throttle posi-
tions.
NOTE:
Increasing the
IFS spring preload too far can
adversely affect the handling of
the snowmobile and rear sus-
pension performance.
To adjust spring preload on the
ski, grasp the spring and turn in
a clockwise
direction (as
viewed from the bottom of the
shock) to increase the preload.
Turn in a counterclockwise
direction to decrease preload.
NOTE:
Reducing the spring
preload too much may allow the
spring retainer to fall off. Al-
ways leave at least one thread
showing above the nut (A).
NOTE:
In the adjacent illustra-
tions, (B) indicates High Pre-
load and (C) indicates low pre-
load.
CAUTION:
If the plastic nut is
unscrewed from the threaded
body the nut will break. Always
leave one thread showing
above the plastic nut or the
spring coils will stack, resulting
in damage.
