5. If the distances from the rear idler wheels to the

inner track drive lugs are not the same on both

sides, an adjustment is necessary.

ADJUSTING

1. On the side of the track which has the inner track

drive lugs closer to the rear idler wheel, loosen the

idler wheel cap screw and the adjusting bolt jam

nut; then rotate the adjusting bolt clockwise 1 to 1

1/2 turns.

2. Check track alignment and continue adjustment

until proper alignment is obtained.

„

NOTE: Make sure correct track tension is main-

tained after adjusting track alignment (see Track
Tension in this sub-section).

3. After proper track alignment is obtained, tighten

both the adjusting bolt jam nut and the idler wheel

cap screw securely.

4. Field test the track under actual conditions; then

make additional adjustments as necessary.

Repair Procedure 2 -

Track/Rear Suspension

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

cedure 2) 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.

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. On models with remote adjuster, rotate the remote

reservoir adjuster knob counterclockwise to

reduce pressure on the skid frame front shock

absorber.

2. On models with the remote adjuster, disconnect

the quick-adjuster located under the driven pulley;

then route the hose out of tunnel and out of the

holding bracket on the inside of the tunnel.

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

ing bolts.

AG670D

! WARNING

If a jam nut is not tightened properly, the adjusting
bolt could loosen causing the track to become dan-
gerously loose.

! CAUTION

If this is not done, damage to the hose may
result.

4. 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.

5. Remove the front cap screws securing the skid

frame to the tunnel. Account for a flat washer and

a lock washer.

6. 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: It is possible to remove and install a wear

strip without removing the skid frame. To do this,
remove the machine screw and lock nut securing
the wear strip at the front of the slide rail; then
align the wear strip with openings (windows) in the
track and drive it rearward off the slide rail. Apply
low-temperature grease to the new wear strip and
slide rail; then align the wear strip with openings
(windows) in the track and drive it forward onto the
slide rail. Secure with the machine screw and lock
nut.

„

NOTE: 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.

AG504D

2. Using a pipe wrench and starting from either end,

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

procedure until the wear strip is free of the rail.

„

NOTE: The wear strip can also be driven off the

slide rail; however, it is quicker to use a pipe
wrench.

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.

AG529D

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

unusual bends. Place the straightedge along the

bottom surface of the slide rail. If the rail is found

to be bent, it must be replaced.

AG536D

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.

AG534D

1. 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 position.
