The following instructions will ensure the proper orientation between the throttle lever and the throttle shaft for Type IV, Type V, Type VI, Type VII and some Type III Governors.
A major feature that originated with the Type IV governor is the fact that the throttle lever is pressed onto the throttle shaft while the governor is running on the calibration bench. This change was made in order to help compensate for a stackup of internal tolerances in the governor, which sometimes made governor calibration difficult. Proper orientation of the throttle lever is important so the governor will pass the calibration procedure. Proper orientation of the throttle lever is also important so the governor will properly interface with the linkage during installation. Some linkage adjustment may still be necessary.
Note: This procedure should be performed whenever a Type IV or Type V governor has had servicing or replacement of internal components. This procedure checks the orientation of the throttle lever. If the orientation is not correct, a new throttle lever must be installed with the correct orientation. If the governor has already been adjusted and the governor is being placed on the calibration bench only to check the settings, this procedure is unnecessary. Go directly to the Testing and Adjusting, "Governor (Type) - Check" section in this manual.
- Install the governor on the 1U-7326 Governor Calibration Bench. For information on installing the governor on the governor calibration bench, refer to the Testing and Adjusting, "Installation Of Governor On 1U-7326 Governor Calibration Bench " section in this manual.
- Back out throttle stop screw (1) .

- Read the governor output position while the throttle lever is in the full throttle position and the bench is running at the "THROT LEV PRESS" rpm.
Note: The throttle lever should be rotated counterclockwise and the radius on the throttle lever should be touching the rear face of the housing. The "THROT LEV PRESS" rpm is specified in the TMI.
- If the governor output position is within the range that is specified in the TMI for "THROT LEV PRESS", the throttle lever is already in the correct position. Proceed to the Testing and Adjusting, "Governor (Type) - Adjust" section in this manual to adjust the governor.
- If the governor output position is not within the range that is specified in the TMI, the throttle lever must be removed and a new throttle lever must be installed with the correct orientation. Refer to the Testing and Adjusting, "Throttle Lever (Types IV, V, VI, VII, and Some III) - Remove" and the Testing and Adjusting, "Throttle Lever (Types IV, V, VI, VII, and Some III) - Install" section in this manual. This procedure checks the orientation of the throttle lever. If the orientation is not correct, a new throttle lever must be installed with the correct orientation.
