TM 9-2350-275-BD ENGINE 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 3-8
