LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - CONTINUED
Is mounted to rear of air compressor, and driven by accessory drive through air compressor. It draws
fuel from fuel tank through fuel filters, and delivers to fuel injectors at the correct pressure for the
power requirements of the engine. The fuel pump is lubricated and cooled by fuel passing through fuel
pump internal passages. Electrically operated shutdown switch is mounted at fuel pump outlet.
Is camshaft gear-driven, through crankshaft gear. Located on front of engine, the accessory drive is
used to drive air compressor and fuel pump. Pulley mounted on front of accessory drive, drives water
pump and fan hub assembly by V-belts.
A centrifugal pump mounted to front of cylinder block. It contains an impeller which draws coolant from
radiator, through water transfer connection, and circulates it through cylinder block, cylinder head
cooling passages, and engine-coolant cooled components. Coolant accumulates heat from engine
operation as it is circulated by water pump which returns it to radiator for heat dissipation.
A two-cylinder reciprocating piston air pump, mounted to and driven by engine accessory drive. Air
compressor is engine-oil lubricated and water-cooled by engine coolant and receives air for com-
pression through pipe and fittings from air intake manifold. Adjustable governor, mounted to air
compressor cylinder head, controls maximum air pressure output. Air compressor outlet is connec-
ted by tubes and fittings to air reservoir.
FRONT ENGINE MOUNTING BRACKET
A steel bracket, with rubber bushings, that supports front of engine when in vehicle frame. It is
attached to engine and bolts to frame crossmember.
