c.
Materials/tools.
Fiberglass sheet or sheet metal (item 5, appx c) or
Clamp
(item 3, appx b)
d. Procedural Steps.
(1) Gain access to the damaged manifold.
(2) Obtain a sealing material (fiberglass sheet preferred), cut sheet to cover the hole or leak.
(3) Secure the sheet in place using hose clamps.
Record the BDAR action taken. When the mission is completed, as soon as practicable, repair the generator using
standard maintenance procedures.
Section V. ENGINE LUBRICATION SYSTEM
4-13. 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 lubrication system
inoperative will degrade the length of the engine life.
4-14. Lubrication System Pump, Failure . The oil pump is needed to provide lubrication to engine components. Low
or no reading of gage or warning light indicates a problem. The main and rod bearings as well as a minimal splash
lubrication of the pistons is possible by overfilling the crankcase with oil. However, the 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 used for normal or limited operation.
a. Limitations.
Severely degraded operation
b. Personnel/time required.
1 soldier/.25-.33 hours
c.

d. Procedural Steps.
(1) Check oil level.
(2) Obtain enough engine oil or substitute to overfill crankcase.
(3) Overfill the crankcase.
