ENGINE
Limitations:
Short moves at low speed only
Personnel/Time Required:
1 soldier
30 minutes
Materials/Tools:
Engine oil
NOTE
Transmission oil, other type vehicle oil or diesel
fuel may be used when engine oil is not available.
Procedural Steps:
CAUTION
Use this procedure only in extreme emergency and operate the
vehicle for short periods of time and at low speeds. The valve train
parts will not be lubricated.
1. Check oil level.
2. Obtain enough engine oil to overfill crankcase by 3 or 4 quarts. New oil or used oil
may be used.
3. Overfill the crankcase. The crankshaft will be submerged in oil and as it rotates it
will splash the lubricant over the main engine parts.
4. Record the BDAR action taken. When the mission is completed, as soon as
practicable, repair tank using standard maintenance procedures.
3-12. OIL LEVEL LOW
General Information:
Oil level low in the engine crankcase.
Substitute lubricants may be used to raise oil
level. Oils other than those designed for use in engines will provide only limited
lubrication. Driver must employ caution and operate the vehicle at lower revolutions
per minute (RPM) (1600) to prevent damage. Diesel fuel is a thin oil and provides only
limited lubrication. Do not dilute the lubrication oil more than approximately 3 parts
diesel fuel to 1 part engine oil except in extreme emergencies. Drive slower to prevent
damage to the engine.
If the engine oil is supplemented with any oil other than that
given in the LO, it will be necessary to change the engine oil and filters as soon as
possible.
