Governor/Actuator Installation

Receiving, storage, and installation requirements for the PGA-EG, PGG-EG, and
PGM-EG 200/300/500 ft-lb (271/407/678 J) governor/actuators are covered in
this manual. Hereafter, these units will be referred to as PG-EG
governor/actuators.
Be careful when handling and installing the governor/actuator. Do not hit the
drive shaft and output shaft. Rough handling can cause damage to seals, parts,
and adjustments.
The PG-EG governor/actuator has been calibrated at the factory to exact
specifications, then drained of oil. A light film of oil covers the internal parts to
help prevent rust. Calibration or internal cleaning is not needed before installation
and operation.
See outline drawings, Figures 2A and 2B, for the following:

Location of hydraulic and electrical connections

Location of optional mode select valve

Hydraulic fitting sizes

Output and drive shaft dimensions
Maintain clearance for removal and servicing of the governor. The governor oil
drain should be easily accessible.
Install the PG-EG governor/actuator on the engine accessory drive pad. A gasket
may be used between the governor and the mounting pad. The drive shaft must
slip into the accessory drive or mating coupling without force. Be careful not to
push the drive shaft into the governor. Improper alignment or too tight a fit
between any of the parts can result in part wear or seizure. This can also cause
jiggle in the governor output.

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.
