Adjust the position of the dial indicator on the indicator bracket so that the dial indicator reads 6.00 mm (0.236 inch). Refer to the appropriate Steps in the Testing and Adjusting, "Installation of Governor on 1U-7326 Governor Calibration Bench " section in this manual for more information. Tighten the locking screw on the dial indicator in order to lock the dial indicator in position.The 6.00 mm (0.236 inch) dimension now becomes the reference point for all other adjustments made on the calibration bench. All of the other governor output dimensions must be reduced by 2.00 mm (0.079 inch) since the 6.00 mm (0.236 inch) reference point is 2.00 mm (0.079 inch) less than the 8.00 mm (0.315 inch) reference point using this modified method.Using the Programmable 1U-8869 Dial Indicator

Turn on the dial indicator and set the dial indicator to reverse mode. Set the dial indicator to reverse mode by pressing the "+/-" button so that the dash (-) appears in the display under the "REV" heading. This setting will allow the dial indicator to display lower values as the stem is pushed in.
Preset the dial indicator to 8.00 mm (0.315 inch). The procedure for presetting the dial indicator is described in the operation manual for the dial indicator.
Install the extension and the contact point on the dial indicator.
Install the 1U-7316 Calibration Pin Group in the governor output clevis. Hook up the throttle spring so that the calibration pin is held tightly against the governor calibration face. The spring will hold the throttle in the high idle position.
Connect the test bench to an electrical outlet.
Turn the switch for the pump to the ON position.
Press the red "zero" button on the dial indicator and insert the dial indicator into the bracket on the calibration bench.
After the tip of the dial indicator contacts the governor output clevis pin, continue to slide the dial indicator into the indicator bracket. When the dial indicator reads -3.00 to -2.75 mm (-0.118 to -0.108 inch), lock the dial indicator in position with the setscrew. This step will ensure proper travel of the dial indicator.
Push the "preset" button on the dial indicator twice. The dial indicator should read 8.00 mm (0.315 inch).
Actuate the throttle in order to ensure that the 8.00 mm (0.315 inch) reference point has not changed.
Remove the calibration pin from the governor output clevis and proceed with the desired checking or the desired adjusting procedures.
