This is a cross section of a hydraulic governor which identifies: 1-Collar. 2-Speed limiter plunger. 3-Lever. 4-Seat. 5-Governor spring. 6-Thrust bearing. 7-Oil passage. 8-Drive gear (weight assembly). 9-Cylinder. 10-Bolt. 11-Spring seat. 12-Weight. 13-Valve. 14-Piston. 15-Sleeve. 16-Oil passage. 17-Fuel rack. The governor valve is shown in the position when the force of the weights and the force of the spring are balanced.When the engine load decreases, the revolving weights speed-up and the toes on the weights move the valve rearward, allowing the oil behind the piston to flow through the drain passage in the center of the valve. At the same time, the pressure oil between the sleeve and the piston forces the piston and rack rearward. This decreases the fuel to the engine and the engine slows down. When the force of the revolving weights balances the governor spring force, the RPM of the engine will be the same as before.When the engine is started, the speed limiter plunger restricts the movement of the accelerator. When operating oil pressure is reached the plunger in the speed limiter retracts and the accelerator can be depressed to the HIGH IDLE position.When the engine RPM is at LOW IDLE, a spring-loaded plunger within the lever assembly in the governor bears against the shoulder of the low idle adjusting screw. To stop the engine, the plunger must be forced past the shoulder on the adjusting screw.Oil from the engine lubricating system lubricates the governor weight bearing. The various other parts are splash lubricated. The oil from the governor drains into the fuel injection pump housing.Fuel Injection Valve
Fuel, under high pressure from the injection pumps, is transferred through the injection lines to the injection valves. As high pressure fuel enters the nozzle assembly, the check valve within the nozzle opens and permits the fuel to enter the precombustion chamber. The injection valve provides the proper spray pattern.
Fuel injection valve cross section. Parts identified are: 1-Fuel line assembly. 2-Seal. 3-Body. 4-Nut. 5-Seal. 6-Nozzle assembly. 7-Glow plug. 8-Precombustion chamber.Lubrication System
This illustration identifies lubrication system components, oil passages and arrows to show the approximate direction of the oil flow in the engine. 1-Oil filter base (includes a bypass valve). 2-Oil passage through the rocker arm shaft. 3-Turbocharger oil reservoir in center section. 4-Oil cooler. 5-Oil cooler bypass valve. 6-Timing gears (in front compartment). 7-Oil pump (in front part of oil pan). 8-Oil filter case. 9-Oil pan (sump). 10-Oil manifold (in engine block assembly).The components in the Lubrication System consists of a sump (oil pan), pump, oil cooler and oil filter. The engine contains an oil manifold and oil passages to direct the oil to the various parts.The pump draws oil from the sump and forces the oil through the oil cooler, oil filter, into the oil manifold. The oil flows through connecting passages to the external and internal engine parts. A regulating valve in the pump body controls the maximum pressure of the oil from the pump.When the engine is started, the lubricating oil in the
