the spindle.

2. Measure the distances to the inside edges of the
skis in two places. Make sure the measurements
are taken behind the spindle mount and ahead of
the spindle mount.


NOTE: Ski alignment is correct when the skis are par-
allel to each other (equal measurements front and rear)
or when the skis have up to a maximum of 1/4" toe out
(front measurement 1/4" more than rear measurement).
3. If ski alignment is not as specified, the snowmobile
will have a tendency to wander and may be difficult

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 determine 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 tie rod.
