WOODWARD UG-8 GOVERNOR
1-Synchronizing motor. 2-Synchronizer knob. 3-Speed droop knob. 4-Compensating pointer. 5-Synchronizer indicator. 6-Load limit knob. 7-Plug.Engine RPM is controlled by changing the compression of the flyweight spring. An A.C. motor (1) mounted to the top of the governor provides for remote control of the spring. A synchronizer knob (2) on the governor dial panel provides control of the same function (engine RPM). The synchronizer indicator (5) directly below the synchronizer knob, indicates the number of synchronizer knob revolutions and resulting spring compression.A speed droop knob (3) provides a means of changing the difference between FULL LOAD RPM and HIGH IDLE (unloaded) RPM. Any difference between HIGH IDLE RPM and FULL LOAD RPM is called "DROOP" and this difference in RPM divided by the FULL LOAD RPM is called "DROOP PERCENTAGE." At zero droop the UNLOADED and LOADED RPM are equal. Providing droop control allows the use of two or more electric sets to power a common load (in parallel). Only one of the paralleled electric sets (with zero droop) senses the variation in power demand and immediately provides the increase or decrease in power while the electric set or sets with high droop governors carry a fixed output.A load limit knob (6) is for the operator to manually limit the engine RPM. This knob provides a positive stop to linkage movement, and provides a quick means of local engine shut off. The engine can be idled to allow slow cooling of the systems and then shut off by turning the load limit body first partially and then completely to zero.A compensator adjustment is provided to adjust the governor sensitivity. Detailed information concerning governor adjustments is provided in the TESTING AND ADJUSTING section of this manual.Plug (7) covers a needle valve adjustment screw that allows the technician to bleed air from the governor hydraulic system at initial installation or during lubrication changes. Loosening the screw causes the hydraulic components to reciprocate more rapidly and purge air to the sump. Final adjustment of the needle valve controls governor response. Compensating pointer (4) provides for governor sensitivity adjustment.Pierce Output Shaft Governor
OUTPUT SHAFT GOVERNOR AND HYDRAULIC SERVO MECHANISM

The output shaft governor (2) and hydraulic servo mechanism are connected by means of an adjustable link (9).The output shaft governor acts as an "assistant operator," automatically reducing engine speed, which in turn reduces converter output shaft speed whenever the load on the converter output shaft decreases. Thus, it acts as a speed limiting device by preventing the output shaft and driven equipment from suddenly and perhaps dangerously, overspeeding. This also relieves the operator of making speed adjustments through the engine governor.The torque converter output shaft maximum speed is either a high speed setting or a low speed setting, which is determined by changing the position of speed change lever (6), normally by remote control. High speed screw (13) determines the maximum speed for the high speed setting, and low speed screw (12) determines the maximum low speed setting. In other words, for either setting there is a predetermined maximum speed which the output shaft cannot exceed.The operation of the governor is the same as most rotating weight-type governors. The governor operates only when the torque converter output shaft attempts to exceed a predetermined maximum speed. This speed is determined by the amount of tension placed on governor spring (7). On a variable speed governor, the spring tension is controlled by rate adjusting screw (5) and the position of the speed change lever. Increasing the spring tension increases the maximum speeds.When the output shaft speed approaches the predetermined governed speed setting, weights (15) are forced out moving thrust sleeve (17) and bearing assembly (18) against the rocker yoke (19). As the output shaft speed reaches the predetermined governor speed setting, the force of the weights overcomes the force of the governor spring and the rocker yoke is moved, rotating the rocker shaft (4). Linkage attached to the rocker shaft overrides the diesel engine governor and reduces engine speed which in turn reduces converter output shaft speed. As the rocker yoke moves outward, it contacts small bumper spring (16) in the end of the governor body, which dampens oscillation of the yoke preventing erratic governor control. A bumper screw positions the bumper spring.As torque converter output shaft speed drops below the maximum governed speed limit, the force exerted by the output shaft governor weights is reduced. Since the governor is then no longer effective, the diesel engine governor takes over full engine control and increases engine speed toward its full governed setting.The terminal lever (3) mounted on the rocker shaft is connected to the hydraulic servo mechanism by the adjustable link (9) and actuating lever (10). Any movement of the rocker shaft is thus transmitted to the hydraulic servo mechanism.
OUTPUT SHAFT GOVERNOR OPERATION
15-Weight. 16-Bumper spring. 17-Thrust sleeve. 18-Bearing assembly. 19-Rocker yoke.The hydraulic servo mechanism consists essentially of a servo piston (24), control valve and the necessary connecting linkage. The piston is connected to the actuating lever by link (21), lever (22) and shaft (20), and fits into the cylinder bore.Oil, delivered from the engine oil pump, flows into the servo mechanism and normally flows through the piston, valve and back to the crankcase. When the output shaft governor takes effect, due to an increase in the torque converter output shaft speed, the governor linkage moves the control valve in the piston. The flow of oil through the piston is blocked and results in an oil pressure build-up. This pressure moves the piston to follow the movement of the valve. This movement continues until the piston ports are uncovered and oil flows through the piston once again.
