e.
A cam and gear on the camshaft drive the fuel
injection pump. The gear drives the pump face gear,
providing fuel distribution to each cylinder in the proper
order. The cam operates the pump plunger, pressurizing
fuel to the nozzles.
f.
A control sleeve meters fuel by controlling the
length of time the plunger spill port is closed, maintaining
pressure, and therefore, the amount of fuel delivered in
each stroke.
g.
The pintle-type injection nozzles are
conventional inward opening with adjustable opening
pressure. They are factory adjusted to open at
1900-1950 psi.

Lubrication System (Fig. 7-3)
a.
The
diesel engine has pressure lubrication to all
working parts.
b.
The
oil system includes oil intake cup, gear-type
oil pump, bypass valve, oil pressure gage, low oil pressure
shut-off, full-flow oil filter, oil cooler, and passages to
deliver oil throughout the engine.
c.
Oil is held in the oil base, and forced through the
oil filter and oil cooler by the pump.
d.
Lines leading to the reeker housing, passages
through the block to crankshaft and to front camshaft
bearing, crankshaft passages to connecting rod bearings,
and connecting rod passages to piston pin bushings
complete the oil system network.
