Snowmobile Arctic Cat (2006 year). Manual - part 21

PREPARATION FOR STORAGE

Prior to storing the snowmobile, it

must be properly serviced to pre-

vent corrosion and component dete-

rioration. An authorized Arctic Cat

Snowmobile dealer should perform

this service; however, the owner/

operator can perform this service if

desired. This service is at the discre-

tion and expense of the snowmobile

owner. To prepare the snowmobile

for storage, Arctic Cat recommends

the following procedure:

1. Clean the seat cushion with a

damp cloth and Arctic Cat

Vinyl Protectant (p/n 0638-

313).

2. Clean the snowmobile thor-

oughly by hosing dirt, oil,

grass, and other foreign matter

from the skid frame, tunnel,

hood, and belly pan. Allow the

snowmobile to dry thoroughly.

DO NOT get water into any

part of the engine.



N OT E : O n 6 6 0 c c m o d e l s ,

change the engine oil and clean
the air filter; then proceed to step
9.

3. Place the rear of the snowmo-

bile up on a shielded safety

stand.

4. On the “Laydown” engine mod-

els, start the engine and allow to

idle. With the engine idling, pry

the intake boot forward; then

spray Arctic Cat Engine Stor-

age Preserver (p/n 0636-177)

into the intakes until the engine

exhaust starts to smoke heavily

or until the engine starts to drop

in RPM. Turn engine off.



N OT E : O n t h e “ L a y d o w n ”

engine models after step 4, pro-
ceed to step 9.



NOTE: On some standard mod-

els, the air-intake silencer is a
one-piece unit, and the silencer
boot(s) can be removed to access
the intake bore(s). Remove the
boots; then proceed to step 8.



NOTE: On some standard mod-

e l s , t h e a i r - i n t a k e s i l e n c e r
includes a cover/tool tray assem-
bly and a baffle/resonator, and the
silencer boot cannot be removed
to access the intake bores. Pro-
ceed to step 5.

5. Open the air-intake silencer

cover; then remove the Phillips-

head screws securing the cover/

t o o l t r a y a s s e m b l y t o t h e

silencer.

6. Close the cover; then tip the

cover/tool tray assembly for-

ward and out of its slots and

remove the assembly.

7. Using a large flat-blade screw-

driver, remove the baffle/reso-

nator tabs from the air-intake

silencer slots and remove the

baffle/resonator to access the

intake bores.



NOTE: The baffle/resonator can

b e r e m o v e d m o r e e a s i l y b y
removing the back tabs first.

8. Start the engine and allow to

idle. With the engine idling,

spray Arctic Cat Engine Stor-

age Preserver (p/n 0636-177)

into the intake(s) until the

engine exhaust starts to smoke

heavily or until the engine starts

to drop in RPM. Turn engine

off.



NOTE: On some models, install

the air-intake silencer boot(s); on
some models, install the baffle/
resonator and the cover/tool tray
assembly.

PREPARATION FOR STORAGE

9. Plug the exhaust system outlet

with a clean cloth.

10. With the ignition switch in the

OFF position:

A. Disconnect the high

tension leads from the

spark plugs; then remove

the plugs, connect them to

the leads, and ground them

on the cylinder heads.

B. Pour 29.5 ml (1 fl oz) of

SAE #30 petroleum-based

oil into each spark plug

hole and pull the recoil

starter handle slowly about

10 times.

C. Install the spark plugs and

connect the high tension

leads.

11. On carbureted models, drain the

gas from each carburetor float

chamber.

12. Fill the gas tank to its rated

capacity; then add Arctic Cat

Fuel Stabilizer (p/n 0638-165)

to the gas tank following direc-

tions on the container for the

s t a b i l i z e r / g a s o l i n e r a t i o .

Ti g h t e n t h e g a s t a n k c a p

securely.

13. On standard chain case models,

drain the chain-case lubricant

by removing the chain-case

drain plug located on the back-

side of the chain-case assembly.

Remove the chain-case cover

and inspect chain, sprockets,

chain tensioner, and rollers for

wear and the chain for proper

tension. Install the drain plug,

chain-case cover, and seal; then

pour the recommended amount

of Arctic Cat Transmission

Lube (p/n 0636-817) into the

filler hole (see Lubrication sec-

tion).

14. On ACT drive gear case mod-

els, change the gear case fluid

(see Lubrication section).

15. Remove the drive belt from the

drive clutch/driven pulley. Lay

the belt on a flat surface or slide

it into a cardboard sleeve to pre-

vent warping or distortion dur-

ing storage.

16. Clean and inspect the drive

clutch and driven pulley.

17. Apply light oil to the upper

steering post bushing, ski spin-

dles and bolts, front and rear

pivot bushings of the skid

frame, and plungers of the

shock absorbers.

18. Lubricate the rear suspension,

spindles, speedometer drive

adapter, and driven shaft sup-

port bearing with a low-temper-

ature grease.

19. Tighten all nuts, bolts, and cap

screws making sure all cali-

brated nuts, bolts, and cap

screws are tightened to specifi-

cations. Make sure all rivets

h o l d i n g t h e c o m p o n e n t s

together are tight. Replace all

loose rivets.

! CAUTION

Do not do step 10 on the 4-
stroke models; severe engine
damage could result.

! CAUTION

Never crank the engine over
without grounding the spark
plugs. Damage to coils and/or
CDI unit may result.

PREPARATION FOR STORAGE

20. Clean and polish the hood, con-

sole, and chassis with Arctic

Cat Ho od and Wi ndshield

Cleaner/ Polish (p/n 0636-174).

DO NOT USE SOLVENTS OR

SPRAY CLEANERS. THE

PROPELLANT WILL DAM-

AGE THE FINISH.

21. On electric start models, dis-

connect the battery cables mak-

ing sure to disconnect the

negative cable first; then clean

the battery posts and cables.

22. If possible, store the snowmo-

bile indoors. Raise the track off

the floor by blocking up the

back end making sure the snow-

mobile is secure. Loosen the

track adjusting bolts to reduce

track tension. Cover the snow-

mobile with a machine cover or

a heavy tarpaulin to protect it

from dirt and dust.

23. If the snowmobile must be

stored outdoors, position the

snowmobile out of direct sun-

light; then block the entire

snowmobile off the ground

making sure the snowmobile is

secure. Loosen the track adjust-

ing bolts to reduce track ten-

sion. Cover with a machine

cover or a heavy tarpaulin to

protect it from dirt, dust, and

rain.

! CAUTION

Avoid storing in direct sunlight
and using a plastic cover as
moisture may collect on the
snowmobile causing corrosion.

PREPARATION AFTER STORAGE

Taking the snowmobile out of stor-

age and correctly preparing it for

another season will assure many

miles and hours of trouble-free

snowmobiling. Arctic Cat recom-

mends the following procedure:

1. Clean the snowmobile thor-

oughly. Polish the exterior of

the snowmobile.

2. Clean the engine. Remove the

cloth from the exhaust system.

Check exhaust system and air-

intake silencer/air filter for

obstructions.

3. Inspect all control wires and

cables for signs of wear or fray-

ing. Replace if necessary. Use

cable ties or tape to route wires

and cables away from hot or

rotating parts.

4. Inspect the drive belt for cracks

and tears. Check belt specifica-

tions. Replace if damaged or

worn. Install the drive belt.



NOTE: If the old belt is worn but

in reasonable condition, retain it
with the snowmobile as a spare in
case of emergency.

5. On carbureted models, inspect

the in-line fuel filter and replace

if necessary.

6. Inspect all fuel hoses and oil

hoses for deterioration or cracks;

replace if necessary. Make sure

all connections are tight; then on

2-stroke models, fill the oil-

injection reservoir with the rec-

ommended 2-cycle oil (see Gas-

oline-Oil sub-section).



NOTE: After prolonged storage

of 2-stroke models, Arctic Cat
recommends one tankful of 100:1
gas/oil mixture be used in con-
junction with the oil-injection sys-
tem to ensure proper lubrication.

7. Inspect the entire brake system,

all controls, headlight, taillight,

brakelight, ski wear bars, and

headlight aim; adjust or replace

as necessary.

8. Inspect the spark plugs.

Replace, gap, or clean as neces-

sary.

9. Adjust the track to the proper

tension and alignment. Lock the

jam nuts.

10. Adjust the carburetor(s) and

choke cable on carbureted mod-

els and throttle cable on all

models.

11. Tighten all nuts, bolts, and cap

screws making sure all cali-

brated nuts, bolts, and cap

screws are tightened to specifi-

cations.

! CAUTION

On carbureted models if the gas
in each carburetor float cham-
ber was not drained prior to
storage, the carburetor(s) must
be cleaned before starting the
engine.

! WARNING

On VM-style carburetors, be
s u r e   t o   t i g h t e n   t h e   s w i v e l
adapter jam nuts securely. If a
j a m  nu t  is n ’t   ti g ht en e d,   t he
adjuster can rotate out of the
c a r bu r e t o r   c a p   c a u s i n g   t h e
throttle slide not to return to the
full-closed position.
