Safety signals
Important information concerning safety is
distinguished in this manual by the
following notations:
The Safety alert symbol means:
Caution! Your safety is involved.
WARNING!
Failure to follow warning instructions
could result in severe or fatal injury
to anyone working with, inspecting or
using the suspension, or to bystanders.
CAUTION!
Caution indicates that special pre-
cautions must be taken to avoid dam-
age to the suspension.
NOTE!
This indicates information that is of
importance with regard to procedures.
Öhlins products are subject to continual improve-
ment and development. Consequently, although
these instructions include the most up-to-date

Notes
WARNING!
1. It´s advisable to have an Öhlins dealer or other
qualified person to fit your shock absorber.
2. Instructions in the vehicle service manual are
to be followed when changing the shock
absorber.
3. When working on a lifted vehicle it must be
securely supported to prevent it from falling.
Mounting Instructions
1
Lift the rear end of the snowmobile so the rear sus-
pension has ground clearance. Make sure it is
steadily positioned and will not fall down.
40 mm
Right
Left
22 mm
CAUTION!
For certain snowmobiles it is not advisible to roll
it over or lay it on it´s side. Especially for ma-
chines with injection oil system, loss of lubrica-
tion due to air in the system can damage the en-
gine. Also fuel can leak from the gasoline tank.
NOTE!
When disassembling suspension components it´s
always easier first to loosen, but not remove all
bolts, before removing the components. Re-
versed order when assembling, tightening all
bolts is the last thing you should do.
2
Release the spring preload of the rear suspen-
sion springs by loosening the nut on the right side.
Hold the spring in a firm grip and pull the shaft out
approxiomately 40 mm. Remove the spring
bracket. Release the spring carefully. It is advis-
able to have a second person assisting.
WARNING!
The springs are very heavily preloaded. It is of great-
est importance to hold the spring in a firm grip when
it´s attachment is beeing removed. There is risk for
damages from squeesing. Use protection gloves.
4
Remove the rear suspensions four attachment
bolts. To loosen the rear bolts it might be neces-
sary to use a 22 mm open-end wrench to hold the
inside nut.
3
When releasing the spring on the left side the two
front idler wheels inside the skid will be released.
When the shaft is removed out on the left side of
the snowmobile, a replacement (i.e. a screwdriver)
must be inserted from the right, to prevent the
wheels from moving away.
Reinsert the shaft when the left spring has been
released. Hold the spring in a firm grip and re-
lease the spring carefully.

5
Loosen the track straining wheels as much as pos-
sible.
NOTE!
Note the track deflection, so it can be reset to
the same position.

6
Press the rear suspension unit together, hoist the
rear end of the snowmobile high enough so it
can be pulled out from the track.
7
Loosen the two limiter straps. Loosen the shock
absorber from the upper attachment.
NOTE!
Take note of the lenght of the limiter strap.
8
Remove the forward, left side idler wheel.
9
Loosen the bolt holding the lower shock absorber
attachment. Remove the shock absorber to-
gether with the spacers by turning the unit, to
free it from the slide rails. To do so, you may have
to loosen the other screws that holds the rails
together.
10
Remove the shock absorber by pulling the hol-
low axle out of the spacers.
11
Fit the Öhlins shock absorber in reverse order,
The cylinder shall be mounted downwards. Start
by reassembling the lower bracket.
12
Put the suspension unit back inside the track to-
gether with the straining wheels.
13
Fit the unit to the chassis by the four attachment
bolts. Preload the springs and fix them in posi-
tion. Set the track defection according to the Artic
Cat Owners manual.
NOTE!
Make sure that all bolts are tightened to the cor-
rect torque and that nothing fouls or restricts the
movement of the shock absorber when the sus-
pension is being fully compressed or extended.
14
Continue your work according to the Öhlins Owners
Manual, section Adjustments.
Rear ride height and suspension comfort
It is very important that the rear ride height is
adjusted correctly. Due to the coupling device in
the rear suspension, the rear ride height and com-
fort are linked together. If the ride height is not
within the right range, the center and rear shock
absorbers may start working parallel in unwanted
situations, thus creating a too stiff suspension
and a harsh ride.
Recommended rear ride height
When you sit on the snowmobile in riding posi-
tion, wearing all your riding gear, we recommend
the coupling adjuster free play to be equal in both
directions, assuming that the coupling adjuster
is in its standard setting.
Equal distance
NOTE!
It is of importance that this adjustment is carried out
on a flat surface and the most correct setting is made
indoors when the snowmobile is thawed out/ warmed
Spring pre-load
is adjusted by
turning the
spring seat.
Increase or decrease the spring preload until you
have reached the middle position of the coupling
adjuster.
Of course, if you carry heavy luggage, or a pas-
senger on a 2-seater, you will need to do this
adjustment with these in place.
NOTE!
The spring preload affects the ride height, it does
not affect bottoming.
It might be necessary to increase the rebound
damping somewhat when using more spring
preload than the delivered setting.
If you experience the suspension bottoming out
too often, do not increase spring preload. It will
not fix your problem, and your ride height might
make your coupling adjuster run out of the range
described above, thus creating a harsh ride. In-
stead, change to a stiffer spring and again ad-
just your spring preload as described above.
If you experience that the suspension is too
stiff, do not decrease spring preload. It will not
fix your problem, and your ride height might
make your coupling adjuster run out of the range
described above, thus creating a harsh ride. In-
stead, change to a softer spring and again ad-
just your spring preload as described above.
