SECTION V. Engine Lubrication Systems
3-8. General.
Engine lubrication is essential for all components.
However, crankshaft bearings and
diesel engine piston crowns are critical components. The pressure lubrication of the
bearings and the cooling spray to the piston crowns are examples of the dual purpose of
the engine lubricant.
By-passing or rendering any portion of the lubrication system
inoperative will shorten the engine life.
