FRAME AS-UPPER 2559693 - Caterpillar

The Caterpillar 3204 Engine is a 5.2 liters (318 cu. in.) displacement, 114 mm (4.5 in.) bore, 127 mm (5.0 in.) stroke, four stroke cycle, 4 cylinder design engine. The firing order is 1-3-4-2 and the direction of rotation is counterclockwise, as viewed from the flywheel. The engine can be either a naturally aspirated, or turbocharged with direct fuel injection.A mechanical governor controls the fuel injection pump output to maintain the engine rpm selected by the operator.Individual injection pumps, one for each cylinder, meter and pump fuel under high pressure to an injection valve for each cylinder.The cooling system consists of a belt driven centrifugal pump, with one thermostat which regulates engine coolant temperature, and an oil cooler.The engine lubricating oil which is cooled and filtered, is supplied by a gear-type pump. Bypass valves provide unrestricted flow of lubrication oil to the engine parts when oil viscosity is high, or if either the oil cooler or the oil filter element should become clogged.Efficiency of the engine performance depends on adherence to proper operation and maintenance recommendations, and use of recommended fuels and lubrication oils.
