The procedures that follow are used to adjust Type V governors after the governors have been assembled. There are certain governor adjustments that must be made during governor assembly. Refer to the Disassembly and Assembly section in this manual for more information.
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.
Verify the position of the throttle lever. Refer to the Testing and Adjusting, "Throttle Lever Orientation (Types IV, V, VI, VII And Some III) - Check" section in this manual.
If the throttle lever is positioned correctly on the governor, proceed with Step 4. If the throttle lever is not positioned correctly, refer to the Testing and Adjusting, "Throttle Lever (Types IV, V, VI, VII And Some III) - Remove" and Testing and Adjusting, "Throttle Lever (Types IV, V, VI, VII And Some III) - Install" sections 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.

(A) The access hole for the load stop adjustment
Remove the plug from access hole (A). To remove the plug, use a hammer and a punch to pierce the center of the plug. Then use a suitable prybar to remove the plug from the access hole.Note: Make sure that the plug does not fall into the governor housing and make sure that the punch does not enter the governor housing. Internal parts of the governor could be damaged.

(1) Spring (2) Throttle stop adjustment screw (3) Low idle adjustment screw (4) The screw for the load stop adjustment
Loosen low idle adjustment screw (3). Loosen throttle stop adjustment screw (2). Both screws should be backed out so the end of the screw is not extending past the housing face.Connect spring (1) to the test bench and to the throttle lever. This will hold the throttle against the throttle stop.
Use a 1U-7299 Rack Adjusting Wrench and a 1U-7300 Hex Wrench to loosen the screw for the load stop adjustment (4). Back out the screw for the load stop adjustment (4) until the screw bottoms out. Remove the cover from the torque limiter. Turn the torque limiter adjustment screw counterclockwise until the screw bottoms out.

(5) Tachometer (6) Speed control knob
Connect the test bench to a 240 V electrical outlet. Turn on tachometer (5) .
Turn the switch for the test bench to the ON position.
Turn speed control knob (6) counterclockwise to the slowest speed. Check all of the fluid connections for leaks. If a leak is found, then the leak must be repaired.Note: 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.Note: Always approach the rpm that is specified in the TMI from a minimum of 100 rpm above the specified rpm. This will ensure accurate test results during the entire test procedure.Note: All specifications for the governor adjustments are found in the TMI. If no values are listed in the specifications for a particular functional test, proceed to the next step in the test.Note: If any of the adjustments for the function checks cannot be performed during the governor setting procedure, stop the procedure and inspect the governor for possible problems.Note: The tolerances that are found in the Governor Performance Data are applicable to all of the governor adjustments. The Expanded Tolerance Band that is referred to in the governor checking procedure is applicable to rechecking a governor that has been previously adjusted.

(1) Spring (2) Throttle stop adjustment screw (3) Low idle adjustment screw (4) The screw for the load stop adjustment
Adjust the speed of the calibration bench to the specified "LOAD STOP ADJ" rpm. Adjust the screw for the load stop adjustment (4) to the output dimension for the "LOAD STOP ADJ".Tighten the locknut for the screw for the load stop adjustment (4) and check the dimension again.
Increase the speed of the calibration bench by a minimum of 100 rpm. Then reduce the speed back to the original "LOAD STOP ADJ" rpm in order to check the governor output dimension again.If the "LOAD STOP ADJ" dimension is not within the specified "RECHECK TOL", perform Step 4 again.
Adjust the speed of the calibration bench to the specified "FUNC CHECK #1" rpm. The "MAX OUTPUT" dimension must be 0.0 mm (0.00 inch).
