Snowmobile Arctic Cat 2-Stroke (2007 year). Manual - part 65

4-34

„NOTE: Some EFI models are equipped with a
control rod activated oil pump. If it must be
removed, the rod simply snaps off and on at the
control arm.

INSTALLING/ADJUSTING

1. Install the throttle cable into the throttle switch

assembly making sure the cable snaps into place.

2. Install the throttle cable end on the throttle lever.

3. Route the throttle cable from the throttle switch

assembly to the throttle body assembly and oil-

injection pump; avoid any sharp bends or moving

components.

4. Attach the throttle cable to the pulley on the throt-

tle body shaft.

5. On the 500 cc, install the oil-injection cable

adjuster on the oil-injection pump; secure with the

jam nuts.

6. On the 500 cc, install the oil-injection cable on the

control arm; secure with a washer and E-clip.

7. Secure the throttle cable to the handlebar and

steering post with cable ties.

8. On the other models, install the handlebar pad and

the console (if applicable).

9. Adjust the throttle cable tension by turning the jam

nuts in the appropriate direction until there is 0.75-

1.5 mm (0.030-0.060 in.) free-play in the throttle

lever and the butterfly completely opens and

closes. Tighten the jam nuts securely.

0741-518

10. Synchronize the oil-injection pump.

! CAUTION

Compress the throttle control lever to ensure free
movement. If the throttle cable sticks or binds, cor-
rect the problem before starting the engine.

Troubleshooting Fuel System

Fuel System

(Related Items)

Some components may vary from model to model.

The technician should use discretion and sound judg-

ment when removing and installing components.

Whenever any maintenance or inspection is made on

the fuel system in which fuel leakage may occur, there

should be no welding, smoking, or open flames in the

area.

„NOTE: Some illustrations and photographs
used in this section are used for clarity purposes
only and are not designed to depict actual condi-
tions.

Oil-Injection Pump

REMOVING

„NOTE: On EFI models to service the oil-injec-
tion pump, the exhaust system and the air silencer
must be removed (see Section 2); then proceed to
step 2.

1. On carbureted models, turn the gas tank shut-off

valve to the CLOSED position.

2. Remove the carburetors/throttle bodies.

3. Disconnect the oil-supply hose from the pump and

plug to prevent oil drainage.

4. Remove the two oil-delivery hoses from the

adapter plates/intake flanges.

5. Disconnect the oil-injection cable/control rod.

6. Remove the two screws, lock washers (if applica-

ble), and washers (if applicable) securing the oil-

injection pump and retainer to the crankcase.

7. Pull the oil-injection pump away from the engine

and account for a gasket.

8. Turn the pump sideways; then remove the lower

union bolt. Account for two gaskets. Remove the

pump.

9. Remove the remaining union bolts securing the

check valves to the pump. Account for two gas-

kets.

10. Remove the check valves. Account for two gas-

kets.
