4. Install the adjuster rods (D) into the swing arm; then

install the adjuster springs (F) and lock nuts (E).

Tighten only until snug.

5. Slide the adjuster rod axle (C) into the adjuster rods;

then install the swing arm axle into the swing arm.

6. Position the articulating skid frame between the slide

rails; then with the adjuster rod axle (C) and the

swing arm axle centered to the mounting holes of the

slide rails, install the cap screws (B) securing the

articulating skid frame to the slide rails.

7. Install new lock nuts to the cap screws (B) and

tighten to 20 ft-lb.

8. Install the rear idler wheel to the mounting block of

the slide rail. Secure with cap screw (A), flat washer,

and lock nut. Tighten to 20 ft-lb.

ADJUSTING

1. Place the skid frame assembly on a flat work surface.

2. Preload the articulating suspension by equally

adjusting the lock nuts on the spring brackets until

both rear idler wheels are 1 in. off the work surface.

Installing Skid Frame

1. Using an appropriate handlebar/steering post support

stand, tip the snowmobile onto one side.

2. Pull the track away from the tunnel and spread open;

then place the skid frame into the track.

3. Position the front of the skid frame into the tunnel

and align the front arm with the appropriate mount-

ing hole in the tunnel. Insert the cap screw with

washers through the tunnel mounting hole and

through the front arm. DO NOT TIGHTEN AT THIS

TIME. Repeat this procedure on the other side.

! WARNING

The spring brackets must be adjusted equally.
Improper adjustment of the spring brackets may result
in binding in the articulating suspension. Upon com-
pleting the adjustment, there must be at least two full
threads behind the lock nuts.

CAUTION

When installing the skid frame, make sure the rear arm
shock mounting location on the pivot/axle is posi-
tioned correctly above the axle or component damage
will occur.
