Manual 03039
Use care while handling and installing the UG-40. Be particularly careful to avoid
striking the governor drive shaft, output shafts, and the speed setting shaft.
Abuse can damage seals and Internal parts. Do not rest the governor on its drive
shaft.
When you receive your UG-40 governor, it will be bolted to a wood platform in a
vertical position. After testing the governor at the factory, it is drained of oil. This
leaves a light film of oil covering the internal parts, preventing rust. No internal
cleaning is required before installation.
Some drive shafts are sprayed with a light film of oil while others (depending on
customer requirements) are covered with a soft seal. Before installation, remove
the soft seal with a rag saturated with mineral spirits.
If a governor Is to be stored for any period of time. refer to Woodward manual
25075: Commercial Preservation Packaging for Storage of Mechanical-Hydraulic
Controls.
1. Make sure the drive shaft rotates freely.
2. Select the correct length of coupling between the governor and the prime

3. Mount the governor squarely on the mounting pad.
4. Make sure that force is not required when installing the governor drive shaft.
5. See Figures 2-1 and 2-2 (Outline Drawing), for mounting hole sizes and
governor dimensions.

Installation

Introduction

The engine, turbine, or other type of prime mover should be
equipped with an overspeed shutdown device to protect against
runaway or damage to the prime mover with possible personal injury,
loss of life, or property damage.
The overspeed shutdown device must be totally independent of the
prime mover control system. An overtemperature or overpressure
shutdown device may also be needed for safety, as appropriate.
