Snowmobile Arctic Cat (2006 year). Instruction - part 5

GENERAL INFORMATION

DRIVE CLUTCH/DRIVEN
PULLEY ALIGNMENT

The parallelism and the offset

between the drive clutch and driven

pulley are set at the factory. Nor-

mally, no adjustment is necessary as

long as neither the drive clutch nor

the driven pulley is removed or dis-

assembled. However, if premature

drive belt wear is experienced or if

the drive belt turns over, the drive

clutch/driven pulley alignment must

be checked. Take the snowmobile to

an authorized Arctic Cat Snowmo-

bile dealer for this service. If not

under warranty, this service is at the

discretion and expense of the snow-

mobile owner.

DRIVE CHAIN TENSION
(Automatic System)

The drive chain must be properly

tensioned for proper operation to

prevent “ratcheting” and unneces-

sary chain/sprocket wear. The chain

tensioner in the drive system is auto-

matic; therefore, no adjustment is

required by the snowmobile owner/

operator. Arctic Cat recommends

that the chain, sprockets, and chain

tensioner be checked for wear and

the chain for proper tension every

year, 1000 miles, or whenever a

drive chain related problem is sus-

pected. Take the snowmobile to an

authorized Arctic Cat Snowmobile

dealer for this service. If not under

warranty, this service is at the dis-

cretion and expense of the snowmo-

bile owner.

DRIVE CHAIN TENSION
(Adjustable System)

The drive chain must be properly

tensioned for proper operation to

prevent “ratcheting” and unneces-

sary chain/sprocket wear. On these

snowmobiles, there are two different

chain tensioners in the chain case.

One chain tensioner is automatic

and one is manual. The automatic

chain tensioner will take up the slack

in the chain under most operating

conditions; however, every 500

miles or whenever repeated hard

accelerations will occur, the manual

chain tensioner should be adjusted.

Arctic Cat recommends that the

chain, sprockets, and chain tensioner

be checked for wear and proper

alignment and adjustment every

year, 1000 miles, or whenever a

drive chain related problem is sus-

pected. Take the snowmobile to an

authorized Arctic Cat Snowmobile

dealer for this service. If not under

warranty, this service is at the dis-

cretion and expense of the snowmo-

bile owner. To adjust the manual

drive chain tensioner, use the fol-

lowing procedure:

1. Loosen the jam nut on the chain

tensioner adjustment bolt.

2. Tighten the adjustment bolt fin-

ger-tight.

! CAUTION

DO NOT attempt to service the
drive clutch and driven pulley.
The drive clutch and driven pul-
l ey mu s t b e s e r v i c e d by a n
authorized Arctic Cat Snowmo-
bile dealer only.

GENERAL INFORMATION



NOTE: If the adjustment bolt

will not turn using the fingers
(because of dirty threads), use a
wrench to loosen the bolt; then
using the fingers, adjust the bolt
until it is finger-tight. Once the
adjustment bolt becomes diffi-
cult to turn by hand, the drive
chain is properly tensioned.

3. Lock the adjustment by bottom-

ing the jam nut against the

chain case.



NOTE: When the head of the

adjustment bolt bottoms on the
jam nut, the drive chain is in need
of being replaced. See an autho-
r i z e d A rc t i c C a t S n ow m o b i l e
dealer for this service.

FUEL PUMP

The fuel pump is designed to pro-

vide adequate amount of gas to the

carburetors (on carbureted models)

or to the injectors (on EFI models) at

all throttle settings. If a fuel deliv-

ery problem is suspected, take the

snowmobile to an authorized Arctic

Cat Snowmobile dealer. If not under

warranty, this service is at the dis-

cretion and expense of the snowmo-

bile owner.

GAS TANK SHUT-OFF VALVE

On certain models, a shut-off valve

is incorporated into the gas hose

coming from the gas tank. The valve

should be turned to the CLOSED

position when trailering or storing

the snowmobile. Turn the valve to

the OPEN position before attempt-

ing to start the engine.



NOTE: On all remaining mod-

els, there is an automatic shut-off
valve incorporated into the fuel
pump which prevents gasoline
flow when the engine is off.

SHOCK ABSORBERS (Standard
Gas)

Each shock absorber should be visi-

bly checked weekly for fluid leak-

age, cracks or breaks in the lower

case, or a bent plunger. If any one of

these conditions is detected, replace-

ment is necessary. Take the snow-

mobile to an authorized Arctic Cat

Snowmobile dealer for this service.

If not under warranty, this service is

at the discretion and expense of the

snowmobile owner.



NOTE: When the snowmobile is

o p e r a t e d i n e x t r e m e l y c o l d
weather (-23° C/-10° F or colder),
a small amount of leakage may be
present. Unless the leakage is
excessive, replacement is not
necessary.

SHOCK ABSORBERS
(Rebuildable Gas)



NOTE: The presence of an ACT

identifier (decal or embossed) on
a shock absorber body indicates
a “rebuildable” shock absorber.



NOTE: The frequency of servic-

ing rebuildable shock absorbers
will vary according to the types of
conditions and terrain the snow-
mobile has been subjected to. If
riding quality deteriorates (or
seems to be deteriorating), take
the snowmobile to an authorized
Arctic Cat Snowmobile dealer for
shock absorber evaluation and/or
servicing. This service is at the
discretion and expense of the
snowmobile owner.

GENERAL INFORMATION

Servicing rebuildable shock absorb-

ers is considered normal mainte-

nance and is the responsibility of the

owner. Take the snowmobile to an

authorized Arctic Cat Snowmobile

dealer for this service. This service

is at the discretion and expense of

the snowmobile owner. Kits are

available to either stiffen or soften

gas shock valving. If changes in

shock valving are desired, see an

authorized Arctic Cat Snowmobile

dealer. This service is at the discre-

tion and expense of the snowmobile

owner.

weather (-23° C/-10° F or colder),
a small amount of leakage may be
present. Unless the leakage is
excessive, replacement is not
necessary.

DEEP-LUG TRACK (Sno Pro
Models)

The Sno Pro models are equipped

with a deep-lug track which is spe-

cially designed for use in powder

snow riding conditions. When the

deep-lug track is operated in hard-

packed snow conditions, it will run

slightly slower than a standard-lug

track and it will accelerate wear strip

wear. To decrease the amount of

wear strip wear, slower speeds must

be maintained when operating on

hard-packed trails. Accelerated wear

strip wear caused by operating a

deep-lug track on hard-packed snow

conditions is NOT covered under

Arctic Cat Inc. warranty policy.

ATTACK 20 TRACK (M-Series/
King Cat Models)

These models are equipped with a

specially designed, directional track

for different operating conditions.

Install the track either with the Deep

Snow arrow positioned toward the

direction of track rotation or with the

Hill Climbing arrow positioned

toward the direction of track rota-

tion.



N OT E : T h e t r a c k m a y b e

removed/installed by the snow-
mobile owner if qualified to do so.
If the owner does not feel quali-
fied, take the snowmobile to an
authorized Arctic Cat Snowmo-
bile dealer for this service. This
service is at the discretion and

GENERAL INFORMATION

TRACK STUDS

0726-207

Studs must be installed only on the

center belt using the pattern illus-

trated. For proper installation, use

the following procedure:

1. Measure 38 mm (1 1/2 in.) in

from the edge of the center belt;

then drill the stud hole using the

proper-sized hole drill.

2. Push the stud through the hole

from inside the track; then place

the domed support plate and

lock nut on the exposed stud.

3. Using a wrench to secure the

stud, tighten the lock nut on the

exposed stud.

It is also recommended that when-

ever studs are installed on a track,

c a r b i d e w e a r b a r s s h o u l d b e

installed on the skis. Carbide wear

bars complement the track studs to

balance steering control under these

conditions. The length of the carbide

on the wear bars should be propor-

tionate to the number of track studs

(i.e. small number of track studs —

short length of carbide...many track

studs — long length of carbide). The

proper proportion between the num-

ber of studs and carbide length on

the wear bar will maintain steering

balance.



NOTE: Stud or hooker plate

installation will void track and
tunnel warranty.

! CAUTION

To protect the tunnel from pos-
sible damage from the studs, it
is recommended that Stud Pro-
tection Wear Strips be installed
o n t h o s e m o d e l s n o t s o
equipped.

! WARNING

Always balance the snowmo-
bile with the proper proportion
between the number of studs
and carbide length on the wear
bars. Do not “over drive” condi-
tions; use common sense in all
operating conditions.

! CAUTION

Do not use studs that are more
than 9.525 mm (0.375 in.) longer
than the track lug height. Also,
do not install studs in the outer
track belts.

! WARNING

Do not operate a snowmobile
with loose studs as they may be
thrown from the track. Always
use a shielded safety stand
whenever performing any main-
tenance or adjustments.
