3. After proper track alignment is
obtained, tighten both the adjusting
bolt jam nut and the idler wheel cap
screw securely.
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.
Adjusting Rear Spring
Tension
Rear spring tension adjustment is accom-
plished by rotating the adjusting cams.
Position 3 provides the stiffest ride, and
position 1 is for the light driver or slow-
speed trail riding. Position 2 is for the
average operator under normal condi-
tions. Always rotate the cam from the
lighter position to the heavier position.

Using a 13/16 in. wrench, rotate the cam
until it is in the desired position. To
stiffen the ride, rotate the cam so as to
raise the spring end. Make the adjustment
on the other cam and be sure both cams
are adjusted equally.
Ski Alignment
The skis have been aligned during setup of
the snowmobile. Ski alignment usually will
not change unless a rock or similar hard
object is hit while the snowmobile is being
operated. Yamaha recommends that the ski
alignment be checked once a week.
Checking
1. Turn the handlebar to the straight-
ahead position.
2. Measure the distances to the inside
edges of the skis. Measure 5 inches
in front of the ski mounting bolt and
5 inches behind the ski mounting
bolt.


NOTE: Ski alignment is correct
when the skis are parallel to each
other (equal measurements front
and rear) or when the skis have up to
a maximum of 3 mm (1/8 in.) “toe
out” (front measurement 3 mm (1/8
in.) more than rear measurement).
3. If ski alignment is not as specified,
the snowmobile will have a ten-
dency to wander and may be diffi-
cult to control; therefore, an
adjustment is necessary.
Adjusting
1. Make sure the ignition key is in the
OFF position.
2. Visually examine the skis to deter-
mine which ski is out of alignment
with respect to the handlebar.
3. Open the hood and loosen the jam nut
on each end of the adjustment tie rod.
4. While holding the ski in position,
rotate the adjustment tie rod until the
measurement between the skis is
within specifications.
! WARNING
If a jam nut is not tightened properly,
the adjusting bolt could loosen caus-
ing the track to become dangerously
loose.
CAUTION
Never force the adjustment cams
from the low position to the high
position. Cam damage may occur.
