LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - CONTINUED

FUEL PUMP

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.

ACCESSORY DRIVE

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.

WATER PUMP

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.

AIR COMPRESSOR

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.
