Oil-Injection Pump
REMOVING
NOTE: On EFI models to service the oil-injection
pump, the exhaust system and the air silencer must
be removed (see Section 3).
1. Remove the carburetors/throttle bodies and secure
them out of the way in an upright position.
NOTE: On the 570 cc, secure the carburetors in an
upright position to avoid gas from running out of the
vent tubes.
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.
6. 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.
7. Turn the pump sideways; then remove the lower
union bolt. Account for two washer gaskets. Remove
the pump.
8. Remove the remaining union bolts securing the
check valves to the pump. Account for the washer
gaskets.
9. 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 48 in.-lb (570 cc) or
to 96 in.-lb (500/600/800/1000 cc).
5. Connect the oil-delivery hoses to the adapter plates.
Secure with clamps.
6. Connect the oil-injection cable/control rod to the
pump and secure.
7. Connect the oil-supply hose to the oil-injection pump
inlet fitting. Secure with the clamp.
8. Bleed the oil-injection system.
