Turn the synchronizer (speed setting) knob clockwise to increase the speed
setting of the governor from its specified maximum plus 10 rpm.
If the friction drive slips before reaching the required high speed setting,
mark the intermediate (278) and the synchronizer (269) (speed setting)
indicator gears, disengage the synchronizer (speed setting) gear (269),
index it one tooth counterclockwise to allow a higher speed setting, and
engage gear again.
The amount of rpm change is not the same if the speeder screw (177) has a
coarse thread (0.7 threads/mm or 18 threads/inch) or a fine thread (1.3
threads/mm or 32 threads/inch).
Re-engage the synchronizer indicator gear (269) with the high-speed stop
pin, engaging the intermediate gear (278) to prevent further increase in
speed. The high-speed stop pin is the pin closest to the gear center.
On governors equipped with an electric speed adjusting motor, be sure the
motor can run the governor up to its maximum-speed stop and down to its
minimum speed. Reset the torque on the friction drive, if necessary, as in
step 11 above.
On governors equipped with a two-position high-speed stop (overspeed test
device), set the overspeed-test speed as described above, then the lever
catch will provide the normal high-speed stop for the governor. If necessary,
set the high-speed stop to the lever engaged position and then disengage
the lever and advance to the normal high-speed stop position to achieve the
overspeed-test speed.
14. To set the minimum speed limit, turn the synchronizer (speed setting knob)
counterclockwise to decrease the speed setting of the governor to its
minimum speed position.
15. Set the synchronizer knob at zero on the dial.
16. Set the synchronizer indicator dial panel pointer at zero.
17. Position the synchronizer indicator knob about 1.6 mm (0.06 inch) from the
surface of the dial. This prevents the knob from binding the synchronizer
system gear train.
18. On governors equipped with micro switches, operate the governor at the
required high and low speeds to verify correct positioning of the cams that
operate the micro switches.
Adjust the cams by loosening the screws and turning the cams on the shaft.
Tighten the screws again.
19. On governors equipped with solenoid shutdown, please refer to Woodward
manual 03013 for set-up procedures.
20. Turn the load limit knob to zero. The load limit indicator must move to zero.
The governor output shaft will move to its minimum fuel position. Reset the
load limit knob to maximum load.
21. Shut down the engine. Remove the pressure gauge and install a 1/8" socket
pipe plug. Apply a pipe sealer to the threads, and torque the pipe plug to 10
N
m (90 lb-in).
