Engine Lubrication: Description and Operation

Fig. 4 V8 engine lubricating system, V6 engine similar:

The diesel engine lubrication system is basically the same as the gasoline engine. The fuel injection pump driven gear is lubricated by oil directed through a passage from the top of the camshaft bearing, Fig. 4. An angled passage in the shaft portion of the driven gear directs the oil to the rear driven gear bearing. At the front of the right oil gallery, a small orifice sprays oil to lubricate the fuel pump eccentric cam on the crankshaft and timing chain. The recommended diesel engine oil is SF/CC or SF/CD.
