Illustration 39 g00367353
Set the drive speed to "Col 4". Place a straight edge across the opening in the shutdown rod and the shutdown rod nut (F). Use a 7/16 inch open end wrench in order to turn the shutdown rod nut (F) counterclockwise until the governor begins to shut down. Once the governor begins to shut down, turn the nut clockwise one full turn.Adjustment Of The Shutdown Device
Note: The electric shutdown device and the pressure shutdown device should be checked prior to the installation, after the installation, and at 1000 hour intervals thereafter.
Failure to test, inspect and maintain these items could result in faulty operation and possible severe engine damage if an emergency shutdown situation occurs.
The electric shutdown is either an Energize-To-Shutoff (ETS) or an Energize-To-Run (ETR). Identify the type of shutdown device in your governor, and make a note of the type of shutdown device.
Visually inspect the pressure shutdown components for signs of burrs, nicks, scoring and/or wear. Repair the components if evidence of a problem exists. Inspect the pressure shutdown gasket. Determine if the gasket is reusable. If necessary, replace the gasket.

(F) Shutdown Rod Nut. (J) Shutdown Rod. (II) Solenoid. (JJ) Jam Nut. (KK) Set Screw. (LL) Shutdown Plunger. (MM) Solenoid Plunger. (NN) Pivot Pin. (PP) Shutdown Lever.
Visually inspect the electric shutdown device and determine if there is any component wear. If the shutdown is an ETS version, pay particular attention to the connection of the shutdown solenoid's plunger and the shutdown lever's link pin.If there is evidence of wear, replace the solenoid. Inspect the gasket on the electric shutdown. Determine if the gasket is reusable. If necessary, replace the gasket.Check the size of spacer on the solenoid plunger in the electric shutdown. Refer to the Service Magazine Article November 19,, "Field Replacement of Spacer to Correct Possible Sticking in Woodward 3161 Governor Electric Shutoff Group".Adjustment Of The Electric Shutdown Solenoid
Energize-To-Shutoff (ETS)
Place the housing of the electric shutdown in a vise. Use copper jaws or shop towels in order to protect the sides of the aluminum die cast housing. Do NOT excessively tighten the vise.Loosen the jam nut (JJ) that holds the solenoid in the electric shutdown's housing. Remove the solenoid coil (II) in order to expose the shutdown plunger (MM) .Note: Loctite 222 is used on the threads of the solenoid coil during manufacturing. In addition, the jam nut is tightened to a torque of 75 N m (55.5 lb ft).
Carefully clean any dirt, metal filings or metal chips from the solenoid plunger and from the cavity in the solenoid coil. Turn the jam nut on the solenoid coil so that the nut will not interfere with the adjustment of the solenoid coil. Reinstall the solenoid coil in the electric shutdown's housing by turning the coil four times.
Hold the housing and the gasket on a
