Oil-Injection Pump (8000)
REMOVING
NOTE: To service the oil-injection pump, the
exhaust system and the air silencer must be removed
(see the Engine-Related Items section).
1. Remove the throttle bodies and secure them out of
the way in an upright position.
2. Disconnect the oil-supply hose from the pump and
plug to prevent oil drainage.
3. Remove the oil-delivery hoses from the adapter
plates/intake flanges.
4. Disconnect the oil-injection cable/control rod.
5. Remove the two screws securing the oil-injection
pump and retainer to the crankcase; then pull the oil-
injection pump away from the retainer/crankcase and
account for a gasket/O-ring.
NOTE: Remove the oil-injection pump from the
crankcase only if the O-ring or gasket need to be
replaced.
6. Turn the pump sideways; then remove the lower
union bolt (4). Account for two washer gaskets (1)

8. Remove the check valves. Account for two gaskets.
INSTALLING
1. In turn on each front union bolt, install a washer gas-
ket, check valve, and washer gasket; then install on
the oil-injection pump.
2. Place the gasket and oil-injection pump near the
engine; then install the lower union bolt through a
gasket, check valve, and gasket.
3. Position the oil-injection pump on the engine making
sure the oil-injection pump gear is correctly aligned
with the oil-injection pump drive gear.
4. Secure the pump with two screws (coated with blue
Loctite #243). Tighten screws to 96 in.-lb.
5. Connect the oil-delivery hoses to the adapter plates.
Secure with clamps.

SYNCHRONIZING in this sub-section). Tighten the
jam nuts securely.
10. Install the throttle bodies.
NOTE: Install the exhaust system and the air
silencer (see the Engine-Related Items section).
SYNCHRONIZING
0746-376
1. Rotate the control rod until the setting for oil pump at
wide open throttle is 1 to 1.5 lines lean. Return the con-
trol rod/throttle cable to the Idle position.
2. Open and close the throttle lever to verify proper
operation and that the throttle linkage returns to the
fully CLOSED position.
Do not adjust the oil
pump at idle, only at WOT.
TESTING
NOTE: These tests must be made with the snowmobile
and oil at a “room” temperature of 20°-30° C (68°-86° F).
CAUTION
When servicing the oil-injection system, use a 100:1 gas/
oil mixture in the gas tank to ensure adequate engine
lubrication. Failure to use the 100:1 mixture to the oil-
injection system will result in severe engine damage.
CAUTION
Assure the throttle cable/linkage has returned to the
fully closed (idle) position and has not remained par-
tially open and moves freely from the open position to
the closed position.
! WARNING
Always wear safety glasses when performing this test.
