a. Priming Lubrication System
CAUTION
Engine lubrication system cannot be primed through bypass filter.
Insufficient lubrication will result, causing damage to engine.
1. Remove plug (4) from gearcase cover flange (3).
2. Connect oil priming pump to orifice (1) in front gearcase cover flange (3).
3. Prime engine (2) until pressure reaches 30 psi (207 kPa).
CAUTION
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.
4. Close fuel shutoff valve and crank engine (TM 9-2320-260-10) for fifteen seconds while maintaining
15 psi (103 kPa) pump pressure.
5. Disconnect oil priming pump and replace pipe plug (4) in gearcase cover flange (3).
6. Check oil level (LO 9-2320-260-12).
b. Out-of-Chassis Run-In
CAUTION
If oil temperature rises sharply above 255F ( 124C), stop engine
immediately and correct as necessary. Failure to do so may
result in damage to equipment.
If any leak or abnormal noise is noted, stop engine immediately
and correct as necessary. Failure to do so may result in damage
to equipment.
