2. Position the tips of the skis against a wall; then using
a shielded safety stand, raise the rear of the snowmo-
bile off the floor making sure the track is free to
rotate.
3. Start the engine and accelerate slightly. Use only
enough throttle to turn the track several revolutions.
SHUT ENGINE OFF.
NOTE: Allow the track to coast to a stop. DO NOT
apply the brake because it could produce an inaccu-
rate alignment condition.
4. When the track stops rotating, check the relationship
of the rear idler wheels and the inner track drive lugs.
If the distance from the rear idler wheels to the inner
track drive lugs is the same on both sides, no adjust-
ment is necessary.

5. If the distances from the rear idler wheels to the inner
track drive lugs are not the same on both sides, an
adjustment is necessary.
Adjusting
1. On the side of the track which has the inner track
drive lugs closer to the rear idler wheel, loosen the
idler wheel cap screw and the adjusting bolt jam nut;
then rotate the adjusting bolt clockwise 1 to 1 1/2
turns.

2. Check track alignment and continue adjustment until
proper alignment is obtained.
NOTE: Make sure correct track tension is main-
tained after adjusting track alignment (see TRACK
TENSION sub-section).
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 conditions; then
make additional adjustments as necessary.
