! WARNING
The tips of the skis must be posi-
tioned against a wall or similar
object for safety.
3. Start the engine and accelerate
slightly. Use only enough throttle
to turn the track several revolu-
tions. SHUT ENGINE OFF.
NOTE: Allow the track to coast to
a stop. DO NOT apply the brake
because it could produce an inac-
curate 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 adjustment 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 Track
Alignment
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 con-
tinue adjustment until proper
alignment is obtained.
NOTE: Make sure correct track
tension is maintained after adjust-
ing track alignment (see Track Ten-
sion section).
3. After proper track alignment is
obtained, tighten both the adjust-
ing bolt jam nut and the idler
wheel cap screw securely.
! WARNING
If a jam nut is not tightened prop-
erly,
the
adjusting
loosen
causing
become dangerously loose.
4. Field test the track under actual
conditions.
5. After the field test, check the
0727-729
alignment of the track. If addi-
tional adjustment is necessary,
repeat Adjusting Track Alignment
procedure.
