MAINTENANCE

3-12. General

a. Maintaining the required oil level in the

engine oil pan is extremely important for long

engine life. If proper oil level is not maintained, the

parts of the engine will run dry, resulting in rapid

wear and premature failure of the engine.

b. The oil level is gaged with a dipstick which

indicates the amount of oil in the engine oil pan.

The engine uses a splash-type oil system in which a

projection on the bottom of the connecting rod

bearing cap dips into the oil with each revolution of

the crankshaft, splashing the oil around the interior

of the cylinder block to lubricate the crankshaft

bearings, connecting r o d b e a r i n g s , c a m s h a f t

bearings, governor parts, cylinder bore, and other

moving parts.

3-13. Engine Lubrication System Service

a. Daily, or at the start of each shift, check the

engine oil level as follows:

(1) Remove the dipstick (1, fig. 3-3) from the

crankcase (2) and check the oil level shown on it.
