3161 Air Pressure Fuel Limiter
Manual 03108
12
Woodward
If the governor output shaft rotates to a position that is lower than specified for
that air pressure, reduce the test stand speed to 0. Wait one minute for the
governor oil pressure to bleed down before removing the governor cover.
Remove the governor cover. Loosen the 7/16 hex head screw and move the
limiter cam (range adjustment) towards the back of the governor. Retighten the
screw. INSTALL THE GOVERNOR COVER and repeat steps 6 and 7 until the
position of the output shaft at maximum pressure is within tolerance.
8.
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.
9.
Replace and tighten plugs over the level adjusting and arming adjusting
screws.
