STARTING REPAIRED OR REPLACED ENGINE (Contd)
PRIMING LUBRICATION SYSTEM
Engine lubrication system cannot be primed through bypass filter.
Insufficient lubrication will result, causing damage to engine.
Remove pipe plug (3) from oil manifold orifice (4) on main oil manifold (2) on left side of engine (1).
Connect oil priming pump hose to oil manifold orifice (4).
Pump oil into main oil manifold (2) under pressure of 30-40 psi (207-276 kPa).
Do not crank engine continuously for more than thirty seconds.
Wait two to five minutes before repeating procedure. Failure to do
so may result in damage to starter motor.
Engage fuel shutoff switch and crank engine (TM 9-2320-386-10) for fifteen seconds while
maintaining 35 psi (241 kPa) pump pressure.
Apply sealant to male threads of pipe plug (3).
Remove oil priming pump hose and replace pipe plug (3) on main oil manifold orifice (4).
Check oil level (TM 9-2320-386-10).
Inspect oil and coolant levels (TM 9-2320-386-10).
Ensure engine compartment is free of all tools and work materials
before starting engine. Failure to do so may result in injury to
If any leaks, abnormal noises, or sudden oil pressure drop is
observed, stop engine immediately and correct as necessary.
Crank engine at cranking speed until oil pressure is observed on gauge.
