Ski Alignment
CHECKING
„
NOTE: Track tension and alignment must be
properly adjusted prior to checking or adjusting
ski alignment. Ski alignment must be performed
on a flat, level surface. Ski toe-out must fall within
the range of 1.6- 6.4 mm (1/16-1/4 in.).
1. Raise the front end of snowmobile just high
enough to keep the skis from contacting the floor;
then tighten the ski mounting cap screws to
6.2 kg-m (45 ft-lb).
2. Turn the handlebar to the straight-ahead position.
Visually inspect the handlebar for being centered
and in the straight-ahead position.
„
NOTE: The hole in the middle of the drag link
should be aligned with the notch (half moon
shaped) in the chassis.
0734-407
„
NOTE: If the handlebar is not in the straight-
ahead position when the hole in the middle of the
drag link aligns with the notch in the chassis, the
steering tie rod must be adjusted. When handlebar
alignment is correct, apply blue Loctite #242 to the
jam nut threaded area and tighten to 1.7-2.1 kg-m
(12-15 ft-lb). Tighten both jam nuts against the
steering tie rod.
3. With the handlebar in the straight-ahead position,
secure the handlebar to prevent the alignment from
becoming disturbed during the remainder of the
alignment procedure.
„
NOTE: Track tension and alignment must be
properly adjusted prior to placing the straightedge
against the outside edge of the track.
4. Place a long straightedge against the outside edge
of the track so it lies near the inside edge of the
left-side ski.

„
NOTE: The straightedge should be long enough
to extend from the back of the track to the front of
the ski.
5. Measure the distance from the straightedge to the
left-side ski wear bar bolts in two places: approxi-
mately 18-20 cm (7-8 in.) in front of the spindle
and 18-20 cm (7-8 in.) behind the spindle. Record
the measurements taken for the left side.
