TM 9-2350-273-BD 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. 3-10
