Servicing Rear Suspension
(F-Series/Z1)
This Rear Suspension sub-section has been organized
so each procedure can be completed individually and
efficiently.

NOTE: Some components may vary from model to
model. Some illustrations and photographs used in
this sub-section are used for clarity purposes only
and are not designed to depict actual conditions. The
technician should use discretion and sound judg-
ment when removing and installing components.

NOTE: Critical torque specifications are located in
Section 1 of this manual.
Removing Skid Frame

NOTE: Many service procedures can be performed
without removing the skid frame. Closely observe the
note introducing each sub-section for this important
information.
1. To avoid having the adjuster bushings binding during
loosening of the track, remove the rear idler wheel
caps and loosen the cap screws on the rear axle.

2. Loosen the jam nuts and two track-tension adjusting
bolts.
3. Place a support stand under the rear bumper; then
while holding the flared bushing, remove the rear
arm assembly cap screws securing the skid frame to
the tunnel.

NOTE: The support stand should hold the snowmo-
bile level but not raised off the floor.
4. Remove the support stand; then using a suitable han-
dlebar support stand, tip the snowmobile onto one
side.
5. Slide the skid frame rearward far enough to drop the
front arm out of the slider axle; then remove the skid
frame.
Wear Strips

NOTE: The skid frame does not have to be removed
for this procedure; however, if wear strip binding or
slide rail damage has occurred, the skid frame
should be removed for this procedure (see Removing
Skid Frame in this sub-section).
REMOVING
1. Remove the machine screw and lock nut securing the
wear strip to the front of the slide rail.


NOTE: If the skid frame was removed due to diffi-
culty in removing the wear strip, use a pipe wrench,
start from either end, and hook the edge of the wear
strip with the pipe wrench jaw and twist the wear strip
off the slide rail. Move the pipe wrench 3 in. and again
twist the wear strip off the rail. Repeat this procedure
until the wear strip is free of the rail.
2. Align the wear strip with the openings (windows) in
the track; then using a suitable driving tool, drive the
wear strip rearward off the slide rail.
