OILING SYSTEM
COMPONENTS
Electrical Circuit (55 V)
The oil injector is powered by the 55 V electrical
circuit. The EMM controls pump operation by rap-
idly connecting and disconnecting the pump’s
internal coil to ground.
The EMM monitors the oil injection pump electri-
cal circuit. If circuit voltage is beyond the specified
range (open circuit), the EMM:
LOW OIL Warning
A sending unit in the oil tank pick-up assembly
monitors the oil level in the oil tank.
If the oil level falls below one-quarter capacity, the
EMM signals:
An optional oil tank sending unit kit is available to
display actual oil level through an I-Command net-
work.
NO OIL Warning
The EMM monitors the electrical circuit of the oil
pressure sensor. If the sensor or circuit fails, or if
there is a lack of oil pressure in the oil distribution
manifold, the EMM:
Cylinder and Crankcase
The primary oil distribution manifold provides
crankcase lubrication through oil distribution
hoses and pressed-in fittings at the front of the
crankcase, port side.
The rear oil distribution manifold provides lubrica-
tion for each cylinder. Each cylinder of the cylin-
der/crankcase has a pressed-in fitting which is
connected to an oil distribution hose.
