Installation Procedures
Introduction
This chapter provides information necessary for receiving, storage, mounting,
and start-up adjustments.
Receiving
When you receive your UG governor, it will be bolted to a wooden 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 soft seal. Before installation, remove
the soft seal with a rag saturated with mineral spirits.
Storage
If a governor is being stored for any period of time, please refer to Woodward
manual 25075,
Commercial Preservation Packaging for Storage of Mechanical-
Hydraulic Controls .
Mounting Requirements
1.
Make sure the drive shaft rotates freely.
2.
Select the correct length of coupling between the governor and the prime
mover drive.
3.
Mount the governor squarely on its mounting pad.
4.
Make sure there is no force pushing the drive shaft into the governor.
5.
See the outline drawing (Figure 1-3) for mounting hole sizes and governor
dimensions.
6.
Make sure the coupling rotates freely but without backlash. Incorrect
alignment of the governor shaft to the coupling, or not enough clearance
between any of the parts, can result in excessive wear and/or seizure of
parts. It can also cause an undesirable high frequency vibration or “jiggle” in
the governor output shaft (see Definitions in Chapter 5 for more
information).
