Page 5: Chapter 1. General Information
38 degrees of terminal (output) shaft travel. Recommended travel from the no-load to the full-load position is 2/3 of full actuator travel. The UG40 Actuator is used on diesel, gas, and gasoline engines (also steam turbines) to replace UG40/32 type governors, providing the advantages of electronic control and load sharing systems with the convenience of the existing UG40 type drive and linkage. -
Page 6: Ug40 Governor Similarities
The UG40 Actuator uses the same cast-iron case as the UG40 governor. The standard UG40 output shaft, power lever, power piston, and piston link are used in the actuator. The base is designed to fit any drive designed for a UG40 governor. -

Do not use oil drained from the UG40 governor. Storage The UG40 Actuator may be stored for short periods of time (less than a year) as received from the factory. For long-term storage (more than a year), storage in an environment with large temperature changes, humid or corrosive atmosphere, etc.,... -
Page 11: Attitude
Make sure that the actuator drive shaft rotates freely. Attitude The UG40 Actuator can be installed in a vertical or near vertical position without affecting its calibration. Do not install more than 45 degrees from vertical. See the outline drawing for installation instructions and dimensions. -
Page 12: Control Linkage
UG40 Actuator Manual 37515 Control Linkage The terminal shaft rotates 38 degrees. Use 2/3 of the total rotation between no load and full load. The additional “overtravel” should be split and used at both ends to provide maximum fuel when required and to assure shutdown at minimum-fuel actuator position (see Figure 2-2). -
Page 13: Oil Supply
The oil in the UG40 Actuator is both a lubricating and hydraulic oil. It must have a viscosity index that allows it to perform over the operating temperature range and it must have the proper blending of additives that cause it to remain stable and predictable over this range. -

Page 15: Oil Maintenance
Manual 37515 UG40 Actuator Actuator oil must be compatible with seal material, that is, nitrile, polyacrylic, and fluorocarbon. Many automotive and gas engine oils, industrial lubricating oils, and other oils of mineral or synthetic origin meet these requirements. Fill the actuator with about 7.0 liters (7.4 quarts) of oil, to the mark on the oil sight glass. -
Page 16: Electrical Connection
Figure 2-7. Wiring for a UG40 Actuator Heat Exchanger Selection A heat exchanger is available for the UG40 Actuator. It consists of a plate mounted on the front of the actuator. Passages are cut in the plate that allow cooling fluid to pass through the plate and remove energy from the actuator. The guidelines for when to use the heat exchanger are not straightforward, and some knowledge of the installation is required. -
Page 17: Chapter 3. Actuator Operation
This chapter provides initial operation instructions for the UG40 Actuator. Initial Operation Before initial operation of the engine equipped with a UG40 Actuator, read all of Chapter 2, Installation Procedures. Make sure that all installation steps have been correctly accomplished and all linkages are secured and properly attached. -

Chapter 4. Principles of Operation Introduction This section describes the operation of the UG40 Actuator. The schematic drawing in Figure 1-3 illustrates the working relationship of the various parts. Connecting oil passages between components is simplified for ease in visualizing the system. -
Page 19: Increase In Load Or Speed Setting
Manual 37515 UG40 Actuator Increase in Load or Speed Setting An increase in load, or speed setting, causes an increase in control current from the electronic control to the torque motor. This, in turn, causes an increase in the torque-motor force, tending to lower the centering adjustment end of the torque motor beam. -
