A mechanical governor controls the fuel injection pump output in order to maintain the engine rpm that is selected by the operator. This provides good engine response and good fuel economy.The cooling system consists of the following components:
Centrifugal pump that is driven by belts
Water temperature regulator which regulates the engine coolant temperature
Oil cooler and radiator which incorporates a shunt systemThe engine lubricating oil that is supplied is cooled. The engine lubricating oil is also filtered. Bypass valves provide unrestricted flow of lubrication oil to the engine components during the following conditions:
High oil viscosity
Plugged oil cooler or plugged oil filter elements (paper cartridge)
