Description
UG10 8526-653 Dial or Lever Governors are identical
Product Description
Mounting base dimensions for the UG-5.7, UG-8, or UG-10 Dial or Lever Governors are identical. See Figure 1 for mounting base dimensions. Place a gasket between the base of the governor and the engine mounting pad. Mount the governor squarely on its mounting pad and in line with the drive.
Torque the mounting bolts evenly. There must be no movement or rocking of the actuator on the engine mounting pad.
Use the correct coupling between the governor and the prime mover drive. Be sure there is no binding, excessive side loading of the governor drive shaft, or looseness in the coupling. There must be no force pushing the governor drive shaft into the governor.
A misaligned drive shaft could break and could cause an overspeed condition or runaway engine.
If the engine drive pad is at an angle (from 0 degrees to 45 degrees maximum), the governor must be installed with the front panel in the upper position.
If an optional keyed drive is used when installing the governor, avoid rough gear teeth and incorrect backlash. Refer to the prime-mover manufacturer’s specifications for the correct amount of backlash and adjustment procedure.
The recommended continuous operating temperature of the oil is 60 to 93 °C (140 to 200 °F). The ambient temperature limits are –29 to +93 °C (–20 to +200 °F.
Use Tables 1 and 2 as a guide in the selection of a suitable lubricating hydraulic oil.
Measure the temperature of the governor on the outside lower part of the case.
The actual oil temperature will be slightly warmer by approximately 6 Celsius degrees (10 Fahrenheit degrees).
Fill the governor with the selected oil to the mark on the oil sight glass. Oil must be visible in the glass under all operating conditions.

Product parameter
Engine Hunts or Surges (A hunt is a rhythmic variation of speed.)
- Adjust and align the linkage. See “Linkage”.
- Adjust compensation and needle valve.
- Add oil up to the mark on the oil sight glass.
- Check for weak spring on yield linkage to fuel rack.
- Gas or steam pressure not steady on prime mover. Adjust gas or steam pressure.
- Check voltage regulator operation. Check for load variation.
- Check engine for misfiring. If misfiring, tune engine.
Fuel Racks Do Not Open Quickly When Cranking Engine
- Inspect the engine-to-governor fuel linkage for binding. If the linkage is not free, adjust as required.
- Verify that the cranking speed is not too low. Use a booster servomotor if necessary.
- If a booster servomotor is used, check the operation of the automatic air starting valve.
- Make sure that the oil grade selection is correct (see Tables 1 and 2).
- Check the oil pressure in the governor. Normal operating pressure is 758 to 827 kPa (110 to 120 psi) for the UG-5.7 and UG-8, and 965 to 1034 kPa (140 to 150 psi) for the UG-10. Return the governor to the factory for repairs if oil pressure does not meet requirements.
Application field
UG software (including UG10 8526-653 and other models) has a wide range of applications, and the following is a detailed summary of its application fields:
Mechanical Design:
UG software is widely used in the field of mechanical design. It can conduct three-dimensional modeling, helping designers present the appearance and structure of products in a more intuitive form. Through the surface design and solid modeling functions of UG software, designers can realize a variety of complex mechanical designs, such as mechanical parts, devices and models. In addition, UG software provides assembly and motion analysis capabilities to help verify the feasibility and performance of the design.
Automotive industry:
In the automotive industry, UG software is an indispensable design tool. Automotive design needs to consider complex shape and structure requirements, UG software provides advanced surface design and component modeling capabilities to meet the needs of automotive designers. Its powerful styling design function helps to realize the fine design and detail carving of the car appearance. At the same time, UG software provides collision simulation, fluid dynamics analysis and other functions to help evaluate and optimize vehicle performance and safety.
Aerospace:
In the aerospace sector, UG software also plays an important role. The design of aerospace products has very high requirements for structure and performance, and the modeling and analysis functions provided by UG software can meet this demand. The advanced simulation and optimization capabilities of UG software can help manufacturers improve product quality through digital simulation in the early stages of development, reducing the cost of designing and building physical prototypes. In addition, UG software’s multi-domain collaborative design capabilities support real-time collaboration among multiple people, improving the team’s work efficiency.
Mold design:
UG software also has a wide range of applications in the mold design industry. UG’s synchronous modeling technology makes it very convenient to modify the model, independent of parameterization and non-parameterization. This feature enables UG to have a high market share in the mold design industry.
CNC machining:
UG software is also widely used in the field of CNC machining. Its processing base module provides the basic framework to connect all processing modules, providing users with a common and friendly graphical window environment. The user can observe the tool’s movement along the path in graphical mode and modify it accordingly.
Product design:
UG software is also widely used in the field of product design, such as home appliance design, mobile phone, computer, printer and other product design. Its powerful modeling and rendering capabilities can meet the design needs of a variety of complex products.
To sum up, UG software has become an indispensable tool in the manufacturing and design fields with its powerful functions and wide range of applications. As technology continues to evolve, UG software will continue to play an important role in multiple fields, driving industry development and innovation.
