8. Remove the slide rail from the skid frame.

INSPECTING

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

1. Inspect the slide rail for cracks or unusual

bends.

2. Inspect the wear strip for wear. The wear strip

must be 10.7 mm (0.42 in.) thick or thicker. If

the wear strip measurement is less than speci-

fied, replacement of both wear strips is neces-

sary.

7. Place the end cap onto the rail and secure with

the cap screw, washer, and lock nut. Tighten

securely.

Installing Skid Frame

1. Place a piece of cardboard on the floor to protect

against scratching and 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 tun-

nel and align the rear suspension arm with the

appropriate mounting hole in the tunnel. Slide

the lock washer onto the cap screw; then secure

the arm to the tunnel with the cap screw and

lock washer. Thread the cap screw in only half

way. DO NOT TIGHTEN AT THIS TIME.

„ NOTE: To aid in centering the rear arm with the
holes in the tunnel, position the skid frame and
track at a 45° angle to the bottom of the tunnel.

4. Place the snowmobile in the upright position;

then secure the opposite side upper idler wheel

assembly.

5. Securely tighten all upper idler wheel mounting

hardware.

6. Tighten all skid frame/axle mounting cap screws

securely.

7. Check track tension; adjust as necessary (see

Track Tension in this sub-section).

Track Tension

„ NOTE: Track tension and track alignment are
interrelated; therefore, always check both, even if
only one adjustment seems necessary.

Track tension is directly related to the overall per-

formance of the snowmobile. If the track is too

loose, it may slap against the tunnel causing wear, or

it may ratchet on the track drive sprockets. Arctic

Cat recommends that the track tension be checked

once a month and adjusted accordingly.

CHECKING

1. Remove excess ice and snow buildup from the

track, track drive sprockets, and the inside of the

skid frame.

! WARNING

Track tension must be properly maintained. Personal
injury could result if a track is allowed to become
excessively loose.

! WARNING

DO NOT attempt to check or adjust track tension
with engine running. Turn ignition key to the OFF
position. Personal injury could result from contact
with a rotating track.

2. Place the rear of the snowmobile up on a safety

stand high enough so the track is free of the

floor.

3. Without exerting any pressure on the track, mea-

sure the distance between the bottom of the wear

strip and the inside surface of the track. The

measurement must be within specifications. If

the measurement is not within specifications, an

adjustment is necessary.

735-669A

ADJUSTING

1. Loosen the idler wheel cap screws.

2. Loosen the rear idler wheel adjusting bolt jam

nuts.

0735-454

„ NOTE: To ensure proper track tension adjust-
ment, perform all adjustments on both sides of the
snowmobile.

3. If the deflection (distance between the bottom of

the wear strip and the inside of the track)

exceeds specifications, tighten the adjusting

bolts to take up excessive slack in the track.

4. If the distance between the bottom of the wear

strip and the inside surface of the track is less

than specified, loosen the adjusting bolts to

increase the slack in the track.

5. Check track alignment (see Track Alignment in

this sub-section).

6. When proper track tension is obtained, tighten

the adjusting bolt jam nuts against the axle hous-

ings.

7. Tighten the idler wheel cap screws securely.

„ NOTE: Since track tension and track alignment
are interrelated, always check both even if only
one adjustment seems necessary.

Track Alignment

Proper track alignment is obtained when the rear

idler wheels are equal distance from the inner track

drive lugs. Excessive wear to the idler wheels, drive

lugs, and track will occur if the track is improperly

aligned. Arctic Cat recommends that the track align-

ment be checked once a week or whenever the track

tension is adjusted.

CHECKING

1. Remove excess ice and snow buildup from the

track, track drive sprockets, and the inside of the

skid frame.

2. Position the tips of the skis against a wall; then

using a shielded safety stand, raise the rear of

the snowmobile off the floor making sure the

track is free to rotate.

3. Start the engine and accelerate slightly. Use only

enough throttle to turn the track several revolu-

tions. SHUT ENGINE OFF.

! WARNING

If jam nuts are not tightened properly, the adjusting
bolts could loosen causing the track to become
extremely loose and, under some operating condi-
tions, allow the idler wheels to climb over the track
lugs forcing the track against the tunnel causing the
track to “lock.” If a track “locks” during operation,
severe personal injury could result.

! WARNING

Make sure the ignition key is in the OFF position and
the track is not rotating before checking or adjusting
track alignment. Personal injury could result if con-
tact is made with a rotating track.

! WARNING

The tips of the skis must be positioned against a
wall or similar object for safety.

9-30

„ NOTE: Allow the track to coast to a stop. DO NOT
apply the brake because it could produce an inac-
curate alignment condition.

4. When the track stops rotating, check the rela-

tionship of the rear idler wheels and the inner

track drive lugs. If the distance from the rear

idler wheels to the inner track drive lugs is the

same on both sides, no adjustment is necessary.

727-729A

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 adjust-

ing bolt jam nut; then rotate the adjusting bolt

clockwise 1 to 1 1/2 turns.

0735-454

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

Procedure 2) has been organized so each procedure

can be completed individually and efficiently. Each

sub-section has (as necessary) Removing, Disas-

sembling, 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 components.

„ 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.

„ NOTE: Critical torque specifications are located
on page 140 of this section.

„ NOTE: If tipped on its side in excess of a 70°
angle (or upside down at all) without the oil hose
being clamped off, return the snowmobile to the
upright position and immediately see Tipped
Snowmobile (660 cc) sub-section in Section 1 of
this manual for proper procedure to follow.

! WARNING

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

! CAUTION

In this section, it will be necessary to tip the 660 cc
snowmobile on its side for accessing some compo-
nents; however, if a 660 cc model must be tipped in
excess of a 70° angle for servicing purposes, use a
suitable clamping device to clamp off the oil hose
next to the valve cover inlet to prevent oil from seep-
ing into the upper engine through the air-intake sys-
tem. Severe engine damage could result if the
engine is run with oil in the upper engine. Care must
be taken to remove the clamping device after servic-
ing.
