Section V. ENGINE LUBRICATION SYSTEMS

TM 5-3835-222-BD

Materials/Tools:

Hose Clamps

Deleted.

Procedural Steps:

a. Gain access to the damaged manifold.

b. Obtain a sealing material (asbestos sheet preferred), cut sheet to cover the hole or leak.

c. Secure the sheet in place using hose clamps.

Record the BDAR action taken. When the mission is completed, as soon as practicable, repair the

equipment using standard maintenance procedures.

Section V. ENGINE LUBRICATION SYSTEMS

4-15. General. Engine lubrication is essential for all moving components; however, crankshaft

bearings and diesel engine piston crowns are critical. The pressure lubrication of the bearings and

the cooling spray to the piston crowns are examples of the dual purpose of the engine lubricant.

Bypassing or rendering any portion of the inoperative lubrication system will degrade the length

of the engine life.

4-16. Lubrication System Pump Failure. The oil pump is needed to provide lubrication to engine

components. Low or no reading of gage or warning lights indicates a problem. The main and rod

bearings, as well as a minimal splash lubrication of the pistons, is possibly done by overfilling the

crankcase with oil. However, components such as a blower, blower drive gears, or turbocharger will

not receive any lubrication from overfilling. Valve train components will also lack lubrication, but

can operate for short time periods. Overfilling the crankcase with oil is a last resort option which

should only be used in case of emergency. Engine failure will occur if use for normal or limited operation.

Limitations:

Severely degraded operation.
