There are certain governor adjustments that must be made during governor assembly. Refer to the Testing and Adjusting, "Governor (Type) - Assemble" section in this manual.
Install the governor on the 1U-7326 Governor Calibration Bench. Refer to the Testing and Adjusting, "Installation Of Governor On 1U-7326 Governor Calibration Bench " section in this manual.Note: If the governor is equipped with a fuel ratio control, a regulated air supply of 140 to 210 kPa (20 to 30 psi) must be connected to the fuel ratio control during the adjusting procedure.
Remove the plug from the access hole. To remove this plug, use a hammer and a punch to pierce the center of the plug. Then use a suitable tool to remove the plug from the bore.
Do not turn the speed control knob unless the test bench is running. Damage to the variable speed drive may result. Except in the event of an emergency, the speed control knob should always be returned to the slowest rpm setting before the calibration bench is turned off.

This will ensure that the test readings are consistent for the entire test procedure.Note: All specifications for the governor adjustment procedure are in
