General Information Introduction This manual describes the operation, repair, and calibration of the Air Pressure Fuel Limiter that is available for the 3161 governor. This device is installed and calibrated at the factory. Description The Air Pressure Fuel Limiter limits fuel in proportion to air pressure from the air manifold or air box.
Oil pressure on the limiter piston is lowered, letting the limit servo spring raise the piston and output rod, allowing the limit/shutdown pilot valve to raise. Fuel limit level is then increased. Woodward...
Fuel Limiter. Refer to manual 03101 to calibrate the governor. Be prepared to make an emergency shutdown when starting the engine, turbine, or other type of prime mover, to protect against runaway or overspeed with possible personal injury, loss of life, or property damage. Woodward...

Fill the governor with 2.2 L (2.3 qt) of clean oil that has a viscosity of 100 to 300 SUS with an oil temperature for continuous governor operation of 66 to 82 °C (150 to 180 °F). Woodward...
Turn the limit level adjustment screw (Figure 3-3) to position the output shaft (terminal shaft) at 38 degrees travel. Apply the specified arming air pressure to the limiter. (If the governor is to be armed at all times, use 0 kPa/psi). Woodward...
0. Remove the governor cover. Loosen the 7/16 hex head screw and move the limiter cam (range adjustment) towards the front of the governor. Retighten the screw. INSTALL THE GOVERNOR COVER and repeat steps 6 and 7. Woodward...

Raise and lower the control air slowly between the specified minimum and maximum pressures. Output shaft position should respond to small changes and seek positions between minimum and maximum specifications proportional to the pressures applied. Replace and tighten plugs over the level adjusting and arming adjusting screws. Woodward...
