1. Clean the snowmobile thoroughly. 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 fraying. 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 specifications. 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 fill the oil-
injection reservoir with the recommended
injection oil.
NOTE: After prolonged storage, Arctic Cat rec-
ommends one tankful of 100:1 gas/oil mixture be
used in conjunction with the oil-injection system
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 each spark plug. Replace, gap, or clean as
necessary.
9. Adjust the track to the proper tension and
alignment. Lock the jam nuts.
10. Adjust the carburetor(s) and choke cable on
carbureted models and throttle cable on all
models.
11. Tighten all nuts, bolts, and cap screws making sure
all calibrated nuts, bolts, and cap screws are
tightened to specifications.
12. Lubricate all grease fittings (rear suspension,
spindles, speedometer drive adapter, and the
driven shaft support bearing) with a low-
temperature grease.
13. On liquid cooled models, check the coolant level
and all coolant hoses and connections for
deterioration or cracks. Add properly mixed
coolant as necessary.
14. On fan cooled models, clean the engine cooling
fins and all vents.
15. On EFI models, place the rear of the snowmobile
on a shielded safety stand; then start the engine.
Allow the engine to idle; then using a long stiff
wire with a hooked end, raise the oil-injection
pump control arm to the wide-open position until
the engine starts to smoke heavily. Release the
control arm and turn off the engine.
16. On electric start models, charge the battery; then
connect the battery cables making sure to connect
the positive cable first. Test the electric start
system.
After Break-In Checkup
(100 Miles)
The 100 mile checkup offered by some dealerships
reduces problems and warranty costs. A program of this
kind should be offered by all dealerships. Many dealer-
ships have added the price of the checkup into the selling
price of the snowmobile, and others offer it as a bonus to
the customers who purchase snowmobiles from their
dealership.
There are three areas that require adjustment after the
break-in period in order to obtain peak performance.
These areas are the following.
A. Carburetor jetting
B. Drive belt deflection/Break-In
C. Track tension and alignment
CARBURETOR JETTING
(Carbureted Models)
—
Altitude, temperature, and the use of oxygenated gaso-
line affect the carburetion needed for optimum engine
performance. The carburetor main jets must be changed
in conjunction with changes in operating altitude, oxy-
genated gasoline usage, and temperature.
DRIVE BELT DEFLECTION — Drive belt deflection
is very important to the snowmobile. Even if it is checked
and is correct when the snowmobile is set up, it does
change (more so during the break-in period). This is
because the rubber engine mounts and the rubber snubber
on the torque link will all take a “set” during the first 100
miles, which allows the distance between the drive clutch
and driven pulley to shorten. When this happens, the
snowmobile will appear to have a too long drive belt. To
add to this, the drive belt itself wears and stretches some-
what. This all leads to a low-end performance problem
and, if not corrected, causes premature drive belt wear.
! WARNING
On VM-style carburetors, be sure to tighten the
swivel adapter jam nuts securely. If a jam nut
isn’t tightened, the adjuster can rotate out of the
carburetor cap causing the piston valve not to
return to the full-closed position.
