INSPECTING
1. Inspect the ball joints for damaged threads or wear.
2. Inspect the tie rod for damage, unusual bends, or
wear.
INSTALLING
1. Thread the jam nuts onto the ball joints; then equally
thread the ball joints onto the steering tie rod.

NOTE: There must be an approximate equal number
of threads exposed on each ball joint.
2. Place the tie-rod assembly into position; then rotate the
steering tie rod until the holes in the ball joints align
with the holes in the steering post and the drag link.
3. Secure the steering tie rod to the steering post with the
new lock nut and tighten to 35 ft-lb; then secure the
steering tie rod and left-side inner tie rod to the drag
link with the cap screw (threads coated with green
Loctite #609) and new lock nut. Tighten to 35 ft-lb.
4. Ensure correct handlebar/ski alignment (adjust steer-
ing tie rod as necessary); then tighten the jam nut

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 1/16-1/4 in.
1. Raise the front end of snowmobile just high enough
to keep the skis from contacting the floor.
2. Turn the handlebar to the straight-ahead position.
Visually inspect the handlebar for being centered and
in the straight-ahead position.
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 prop-
erly 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.
729-887B

NOTE: The straightedge should be long enough to
extend from the back of the track to the front of the ski.
! WARNING
Neglecting to lock the tie rod by tightening the jam
nuts may cause loss of snowmobile control and possi-
ble personal injury.
