Maintenance

Fuel Filter - CFI Models

1.

The fuel filter should be replaced as outlined in the
periodic maintenance table. For information involving de-
pressurizing the fuel system and disconnecting fuel hoses,
See “Cleanfire™ Fuel Injection” on page 4.15.

2.

After de-pressurizing the fuel system and disconnecting the
fuel hoses, remove the fuel filter cartridge from the bracket.
Dispose of any fuel in an appropriate container, then
discard assembly.

3.

When re-connecting the fuel hoses, verify the connections
are secure by firmly pulling on the two hose connections.
Push the filter cartridge back into the bracket.

4.

To prime the fuel system after installing a new filter,
connect a 12 volt Vdc battery to the fuel pump prime plug.
See “Diagnostic Plugs” on page 11.18.

Oil Filter

All models feature an inline oil filter located between the oil
reservoir and oil pump. Always bleed the oil supply hose and oil
pump of air after replacing the filter.

Install the oil filter so that the directional arrow points towards
the oil pump.

WARNING

When removing the fuel filter fuel spillage will occur. Be 

sure to work in a well ventilated area away from 

anything which may cause the fuel to ignite such as an 

open flame, heaters, trouble lights or cigarettes.

Fuel Tank Vent System

All models feature a fuel tank vent / vacuum check valve system.
There are two systems used depending on the model year of the
snowmobile.

On some models, the vent / vacuum check  valve system
resembles the illustration below.

When inspecting the system, verify the hoses are not cut or
kinked.

Some models feature a rollover check valve / vent / vacuum
check valve assembly bonded to the inside of the fuel tank. The
rollover check valve prevents fuel from escaping the tank in the
event of a vehicle rollover.

The rollover check valve is not serviceable. When inspecting the
system, verify the hose is not kinked.

Air Intake Box / Pre-Filters

Inspect the inside of the air intake box and pre-filters for foreign
material and/or damage.

NOTE: All 2007 and some 2008 CFI models were
manufactured with a two-piece airbox where an
adapter plate was secured to the throttle body. The
airbox then snapped into the adapter plate to make
the airbox assembly.
The two-piece air box is no longer available. A one-
piece air box is the direct replacement. The new air
box features adaptor boots that are pinned to the air
box. A set of gear clamps secure the boots to the
throttle body assembly.

Inspect the console-mounted pre-filters for damage, and foreign
material. Replace filter(s) or clean if required.
