Engine Lubrication: Description and Operation

Fig. 4 Engine Lubricating System:

On 1980 engines, the recommended diesel engine oil designation is SE/CC. On 1981 engines, the recommended diesel engine oil is SF/CC, SF/CD or SE/CC. On 1983---84 engines, the recommended diesel engine oil is SF/SC or SF/CD, it is also recommended that the oil be a fuel saving product.
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.
