3-9. OIL PUMP FAILURE
General Information
Oil pump fails to supply sufficient lubricant to the engine. The suggested solution will
provide limited lubrication of the main and rod bearings, however, the rocker arm
bearings, push rod clevis bearings, camshaft bearings and cam followers will not receive
any lubrication. The wrist pins, piston skirts and cylinder walls will receive minimum
lubrication. During a past modification to the camshaft journal oil openings, failure to
increase oil pump capacity caused engine failure because of galling of the cylinder
liners during dynamometer testing. Of more importance, perhaps, is the lack of
lubrication for blower and the idler gear bearings. Early failure of the blower will
occur without proper oil pump operation. This procedure should only be used as a last
resort.
Limitations:
●
Severe mobility restrictions
Personnel/Time Required
●
1 soldier
●
10 minutes
Materials/Tools:
●
Oil
Procedural Steps:
1. Check for broken oil lines or cooler.
2. Overfill engine with any available motor or gear oil. This will provide a limited
splash system in the crankcase to lubricate bearings and cylinder walls.
3. Record the BDAR action taken. When the mission is completed, as soon as
practicable, repair the vehicle using standard maintenance procedures.
3-10. OIL PAN HOLES
General Information
Repair of oil pan leakage due to cracks or holes can be attempted without removing the
power pack. If the oil pan leak is inaccessible, remove the power pack to repair.
Limitations:

None
