Servicing Chart

This chart is designed to direct the technician to the

appropriate Repair Procedure for servicing the rear

suspension. Select the snowmobile model from the list

and follow the chart to attain the repair procedure.

Repair Procedure 1 -

Track/Rear Suspension

This Track/Rear Suspension sub-section (Repair Pro-

cedure 1) has been organized so each procedure can be

completed individually and efficiently. Each sub-sec-

tion has (as necessary) Removing, Disassembling,

Cleaning and Inspecting, Assembling, and Installing

procedures. Some components may vary from model

to model. The technician should use discretion and

sound judgment when removing and installing compo-

nents.

„NOTE: Critical torque specifications are located
on page 6 of this section.

„NOTE: Some illustrations and photographs used
in this sub-section are used for clarity purposes
only and are not designed to depict actual condi-
tions.

Removing Skid Frame

„NOTE: Many service procedures can be per-
formed 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

when loosening the track, remove the rear idler

wheel caps and loosen the cap screws on the rear

axle.

FS082A

2. Loosen the jam nuts and two track-tension adjust-

ing bolts.

MS062A

3. Place a support stand under the rear bumper; then

while holding the flared bushing, remove the rear

cap screws securing the skid frame to the tunnel.

Account for lock washers and flat washers.

„NOTE: The support stand should hold the snow-
mobile level but not raised off the floor.

4. Remove the front cap screws securing the skid

frame to the tunnel. Account for a flat washer and

a lock washer.

5. Remove the support stand; then tip the snow-

mobile onto one side using a piece of cardboard to

protect against scratching. Remove the skid frame.

Wear Strips

REMOVING

„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).

1. Remove the machine screw and lock nut securing

the wear strip to the front of the slide rail.

MS016B

„NOTE: If the skid frame has been removed due to
difficulty in removing the wear strip, it may be nec-
essary to 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 7.5 cm (3 in.) and again
twist the wear strip off the rail. Repeat this proce-
dure 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.

CLEANING AND INSPECTING

„NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.

1. Clean the slide rail using parts-cleaning solvent

and compressed air.

2. Inspect the slide rail for cracks. If any cracks are

found, replace the slide rail.

3. Using a straightedge, inspect the slide rail for any

unusual bends. With the slide rail removed, place

the straightedge along the bottom surface of the

slide rail. If the rail is found to be bent, it must be

replaced.

INSTALLING

„NOTE: Apply a light coat of grease to the slide
rail surface to aid in installing a new wear strip. If
there are any sharp edges on the lower portion of
the rail, use a file to remove them.

1. Align the wear strip with the openings (windows)

in the track and from the back, start the wear strip

onto the rail; then using a block of wood and a

hammer, drive the wear strip forward into posi-

tion.
