A Series Diesel Engine Lubricating System Flow 115
The main bearings and the valve train are lubricated
by pressurized oil directly from the main oil rifle. The
other power components, connecting rods, pistons,
and camshaft receive pressurized oil indirectly from
the main oil rifle.
The drillings in the crankshaft supply oil to the
connecting rod bearing. The oil is supplied to the
camshaft journals through drillings in the main
bearing saddle. Smaller drillings in the main bearing
saddle supply oil to the piston cooling nozzles. The
spray form the nozzles also provides lubrication for
the piston pins.
The number five main bearing saddle does not
contain a piston cooling nozzle. Cylinder Number One
receives the lubricating and cooling spray from the
nozzle located in the Number One Bearing Saddle.
Cylinder Number Two receives the spray form the
Number Two Bearing Saddle, etc..
Lubrication for the valve train is supplied through
separate drillings in the cylinder block. The oil flows
through the drillings and across the oil transfer slot in
the cylinder head gasket. From the transfer slot, the
oil flows around the outside diameter at the cylinder
head capscrew, across a slot in the bottom of the
rocker lever support, and up a vertical drilling in the
support. From these drillings, oil flows through
drillings in the rocker lever support. From these
drillings, oil flows through drillings in the rocker lever
shaft to lubricate the rocker levers. Oil flows through a
drilling in the rocker levers to fill a channel cast into
the top of the levers. The oil from the channel
lubricates the valve stems, push roads and tappets.
