Page 5: Chapter 1. General Information
Chapter 1. General Information Description The 3161 governor is a mechanical-hydraulic device that senses speed and is mechanically linked to and controls the energy source of dual fuel engines, diesel engines, or steam turbines. The maximum work output is 6 ft-lb (8 J) over the full 42 degrees travel of its output (terminal) shaft. -

Page 7: Chapter 2. Installation Procedures
Attach the prime mover linkage to the output shaft of the governor. The maximum work output of the 3161 governor is 6.0 ft-lb (8.1 J) over the full 42 degrees travel of its output shaft. The recommended travel of the output shaft is 28 degrees between the no load and full load positions. - Page 8 3161 Governor Manual 03101 Speed Setting Shaft Linkage Attach the speed setting linkage to the governor speed setting shaft. Typically, there will be a 50 rpm speed change for each degree of speed setting shaft rotation, however this may vary depending on the speed setting spring used in the governor.

Oil Viscosity Chart Needle Valve Adjustment After the prime mover has started and the governor is controlling, open the needle valve (turn it CCW) until governor operation just becomes unstable. Then slowly close the needle valve (turn it CW) until the governor just becomes stable.

Page 10: Chapter 3. Principles Of Operation
3161 Governor Manual 03101 Chapter 3. Principles of Operation Component Description Gerotor Oil Pump—The gerotor oil pump is located in the base of the governor. The inner rotor of the pump is driven by a pin in the drive shaft, and carries the outer rotor around in mesh, pumping oil to the accumulator piston. - Page 11 Speed Droop The 3161 governor is an isochronous governor with the ability to operate in the droop mode by the adjustment of the internal droop pivot pin. The governor may be used in the droop mode to allow for load division between two or more prime movers connected to a single shaft or for operating in parallel.

Page 12: Operation Of The 3161 Governor
The schematic arrangement of the 3161 governor is shown in Figure 3-1, with the governor pilot valve calling for increased fuel. The 3161 governor has a self- contained oil supply (approximately 2.3 US qt/2.2 L). The oil passes from the suction side to the pressure side of the gerotor pump as the drive shaft is rotated by the prime mover. - Page 13 Manual 03101 3161 Governor Shutdown The limit/shutdown pilot valve is located in the supply line to the ballhead pilot valve plunger. When shutdown is initiated, the shutdown strap pushes the limit/shutdown plunger below the supply passage and drains oil from the supply to the ballhead pilot valve plunger.
