Oil Injection
Page 3C-12 90-8M0050731 MAY 2011
There are two methods for priming the oil injection pump. Each method is unique to the condition that requires the priming of the
oil injection system.
Conditions Requiring Priming the Oil Pump
Condition Priming Procedure
New engine Use Method 1
Rebuilt powerhead Use Method 1
New powerhead Use Method 1
Oil system ran out of oil Use Method 2
Oil drained from oil supply hose feeding pump Use Method 2
Oil pump removed Use Method 2
Oil injection hoses drained Use Method 2
Method 1 ‑ Computer Diagnostic System Break‑in Clock Reset
This method should be used for a new engine, a new powerhead, or a rebuilt powerhead. This method ensures the oil injection
system does not have air pockets trapped in the pump or oil hoses, and resets the break‑in clock. Follow the procedures in the
computer diagnostic system for resetting the break‑in clock.
Method 2 ‑ Computer Diagnostic System Oil Pump Prime
This method should be used when the break‑in clock does not need to be reset. Use this method if the oil injection system ran
out of oil, the hose supplying the oil pump was leaking or removed, the oil pump was replaced, or if any of the oil supply hoses
were leaking or removed. This method can also be used to test the output volume of the oil injection pump. Follow the procedures
in the computer diagnostic system for priming the oil pump.
Remote Oil Tank Hose Connections
1. Verify the oil hose with the blue stripe coming from the remote oil tank has an oil filter installed. This filter is directional and is
marked with an arrow. The arrow must point towards the engine‑mounted oil reservoir.
2. Install the oil hose with the blue stripe and filter onto the T‑fitting. Secure the oil hose with a cable tie.
