Priming the Oil Pump
IMPORTANT: Before starting engine for the first time, prime the oil injection pump.
Priming will remove any air that may be in the pump, oil supply hose, or internal passages.
NOTE: If a new powerhead is being installed or oil hoses/oil pump has been removed,
it is recommended all air be purged from oil pump/oil lines using gearcase leakage tester
(FT-8950). Connect the leakage tester to the inlet t-fitting on the onboard oil reservoir.
While clamping off the inlet hose, manually pressurize the reservoir to 10 psi. Using the
Digital Diagnostic Terminal 91-823686A2, activate the oil pump prime sequence. Main-
tain the 10 psi pressure throughout the auto prime sequence. When the auto prime is
completed, remove the leakage tester and refill the onboard oil reservoir.

Priming the oil pump (filling pump and hoses using pressure) is required on new or rebuilt
power heads and any time maintenance is performed on the oiling system that allows air
into the oil system.
There are three methods for priming the oil pump:
METHOD 1 – SHIFT SWITCH ACTIVATION PRIME
This method does three things:
a. Fills the oil pump, oil supply hose feeding pump and oil hoses going to the crank-
case and air compressor.
b. Activates break-in oil ratio.
c. Initiates a new 120 minute engine break-in cycle.
Refer to priming procedure following.
METHOD 2 – (DDT) DIGITAL DIAGNOSTIC TERMINAL – RESET BREAK-IN
This method is the same as Method 1, except the run history and fault history are erased
from the ECM.
Refer to procedure in the Technician Reference Manual provided with the Digital Diagnos-
tic Software Cartridge Part. No. 91-880118A2.
METHOD 3 – (DDT) DIGITAL DIAGNOSTIC TERMINAL – OIL PUMP PRIME
This method fills the oil pump, oil supply hose feeding pump, and oil hose going to vapor
separator.
Refer to procedure in the Technician Reference Manual provided with the Digital Diagnos-
tic Software Cartridge Part. No. 91-880118A2.
