Woodward PSG Governor Adjustments
Adjust the fuel control linkage before you adjust the governor. Refer to Specifications, "Carburetor Control Linkage".Initial Operation
Perform the following procedure for a new governor or for a governor that has been serviced:
Illustration 1 g00677571
Electric Woodward PSG Governor
(1) Knob
(2) Compensating valve
Start the engine and allow the engine to run until normal operating temperature is achieved.
Adjust the engine speed, if necessary. If you have an electric governor, use the remote control and the motor for the speed adjustment.If you have a nonelectric governor, turn knob (1) or turn the adjusting screw.
Open compensating valve (2) for one to two turns. The engine will hunt. Allow the engine to run for about 1/2 minute while the valve is open. This will allow air to be purged out of the governor's oil passages.
Gradually close compensating valve (2) until the hunting stops. Adjusting the High Idle Stop
Start the engine. Run the engine until normal operating temperature is achieved.

Typical nonelectric PSG governor
(1) Stop screw
(2) Adjusting screw
Loosen the locknut for stop screw (1). Turn the stop screw counterclockwise for approximately two turns.
With the stop screw in this position, the engine can overspeed. This can cause damage to the engine components. Be ready to shutdown the engine if it has an overspeed condition.
Adjust the engine to the desired high idle rpm. If you have an electric governor, use the remote control and the motor for the speed adjustment.If you have a nonelectric governor, turn the knob or turn adjusting screw (2).
After the desired high idle rpm is reached, turn stop screw (1) clockwise until the screw stops. Tighten the locknut. Observe the engine rpm on the tachometer. If the engine speed is still correct, the adjustment is correct.Checking the Speed Droop
This engine has adjustable speed droop. The adjustable speed droop is between zero and seven percent. This amount will be different for different applications. This percent of adjustable speed droop is the percent between the high idle speed (no load) and the engine full load speed. In order to calculate the adjustable speed droop, use the equation in Table 1.
Table 1
Equation for Calculating the Percent of Speed Droop
H − F × 100 = % Droop
F
H is the high idle rpm.
F is the full load rpm.
Multiply the full load speed by the desired adjustable speed droop. Add the number from this multiplication to the full load speed. This will calculate the speed at no load (high idle rpm).
Start the engine. Run the engine until normal operating temperature is achieved.
Operate the engine at high idle rpm. Observe the tachometer.
Connect a known load to the engine. The load must be less than the full load for the engine. Observe the tachometer. Record the amount of decrease in engine speed.
Determine the ratio between the load that is on the engine and the engine's rated load. The ratio must be equal to the ratio of the decrease in engine speed. See Table 2.
Table 2
Ratio for Verifying the Speed Droop
Known load = Decrease in engine rpm from Step 4
Rated load Droop from Step 1
Table 3
Example of the Ratio for Verifying the Speed Droop
105 kW = 27 rpm
210 kW 54 rpm
If the ratios are not equal, an adjustment is necessary. Remove the load and stop the engine. If the engine speed has decreased too much, the speed droop must be decreased. If the engine speed did not decrease enough, increase the amount of speed droop.Adjusting the Speed Droop
Illustration 3 g00743802
(1) Bracket
(2) Set screw
(3) Lever
(4) Stop screw
Mark the position of bracket (1). This will show the amount that the bracket moves in order to change the speed droop.
Loosen set screw (2) that holds bracket (1) and lever (3).
To increase the speed droop, turn lever (3) in the counterclockwise direction. To decrease the speed droop, turn the lever in the clockwise direction. Note: If the lever is turned too far in the clockwise direction, the engine will hunt.
Tighten screw (2) in order to hold the lever and the bracket in position.
Check the speed droop after an adjustment is made. Several adjustments may be necessary in order to achieve the desired setting.
When lever (3) is in the position that provides the desired speed droop, set stop screw (4) against the lever. Mark the position of the lever. If the governor is serviced, the stop screw facilitates resetting of the speed droop.
