A gear-type pump draws oil from the crankcase and delivers it through a replaceable oil filter to the engine. Normal oil pressure
should be 25 psi (172 kPa) or higher under normal operating conditions. A crankcase oil drain valve with operating handle is
provided to drain the lubricating oil without removing the unit from the vehicle.
Constant speed is set to maintain engine speed at 2000 100 rpm. The governor uses a ball-and-cup mechanism on the camshaft
gear as the sensing device. A yoke resting on the cup connects to an arm-and-spring mechanism controlling the throttle lever.
Any change in engine speed is transmitted from the cup to the yoke and to the throttle. The speed may be adjusted by changing
the spring tension.
The fuel system consists basically of a primary and secondary fuel filter, fuel transfer pump, injection pump, and injection
nozzle. The transfer pump, operating off the camshaft, draws fuel from the supply tank and delivers it through the two filters to
the injection pump. The injection pump meters and delivers the fuel at high pressure to the nozzle.
