Install the gasket and backplate on the water pump. Rotate the fan holder to confirm there is no obstruction or interference. It is housed in the gear case. A flyweight assembly is mounted on the camshaft. The movement of the flyweight is transmitted to the injection pump control rack by way of the slider, control lever, and link, 1. A spring which is hooked to the arm, 3, and tension lever, 4, regulates the movement of the flyweight.
By changing the set angle of the governor lever, tension on this spring is changed. Thus, the engine speed can be regulated by the governor lever. Maximum Speed Set Bolt The set bolt is mounted on the cylinder block. This bolt limits the movement of the arm and has been adjusted and sealed at the factory.
Maximum Fuel and Start Spring These are built into the cylinder block to regulate fuel injection at high speed. Regulation of fuel injection in the middle speed range is by torque spring to realize higher torque. A start spring, 2, is placed between the gear case and link. This spring automatically functions to increase fuel during the start mode. An idling spring at the gear case stabilizes engine idling speed. The maximum fuel has been adjusted at the factory and sealed. Reassembly Precautions Before Assembling Wash parts before assembling especially oil gallery, bearings, pistons, and cylinder bores should be washed thoroughly.

Apply new oil to sliding and rotating surfaces of cylinder bores, pistons, and bearings, etc. During the engine speed increase, tension is placed on the governor spring, 2. As the engine speed increases, the four governor weights, 1, pivot outward and push on the slider cone, 2. The weights and slider cone are located on the end of the camshaft.
The slider cone, 2, Figure , contacts the governor linkage arm, 1, at contact pad, C. As the cone moves forward, it pushes the linkage arm, 1, forward, which is connected to the injection pump rack assembly. When the injection pump rack moves forward, the fuel delivery is decreased and the engine speed decreases. As the engine speed decreases, the governor weights, 1, pivot inward allowing the slider cone, 2, to move rearward.
As the slider cone, 2, Figure , moves rearward, the governor linkage arm, 1, allows the fuel injection pump rack to move rearward to the full fuel position and the engine speed increases. Engine speed depends upon several factors: the throttle setting determined by governor spring tension; the pressure exerted by the slider cone on the governor linkage; and, positioning of the injection pump rack.
All the governor linkage parts are located inside the engine timing gear cover. To inspect or replace any of the governor linkage parts, the timing gear case and injection pump must be removed from the engine. Relief valve tightening torque: 43 ft.
