Remove the large O-ring seal from the front of the governor. Align the drive coupling on the calibration bench with the governor drive gear by rotating the governor until the two drive pins in drive coupling (1) engage with the governor drive gear.
When the drive pins engage with the governor drive gear, rotate the governor in order to align the mounting holes in the governor housing with the mounting holes in the governor calibration bench.
To fasten the governor to the calibration bench, use the same bolts and washers that are used to fasten the governor to the engine. If the governor mounting bolts are not available, use three 6V-5218 Bolts with three 9M-1974 Hard Washers .
Install fittings (2), (3), and (5) in the governor. Install fitting (4) if the governor is equipped with a fuel ratio control.Note: Step 6 is optional. If the governor calibration bench can successfully perform the entire procedure, then the fuel transfer pump can remain in position on the governor.
Remove the fuel transfer pump from the governor housing. Refer to the Disassembly and Assembly, "Governor (Type) - Disassemble" section in this manual for additional information.

(6) Line from the fuel transfer pump (7) Line to the sump (8) Pressure line from the filter base
Connect line (7) from the sump to fitting (3) for the fuel transfer pump outlet.
Connect line (8) from the filter base to fitting (5) for the oil inlet on the governor.
Connect line (6) from the fuel transfer pump to fitting (2) for the inlet fitting of the fuel transfer pump.
If the governor is equipped with a fuel ratio control, connect a regulated air supply (hand pump or squeeze pump) to the fuel ratio control. Turn on the regulated air supply in order to pressurize the fuel ratio control.Note: A regulated air supply of 140 to 210 kPa (20 to 30 psi) must be used to avoid damage to the fuel ratio control.
Install the pressure gauge that is supplied with the governor calibration bench on the quick disconnect fitting on the filter housing for the lubricating oil.Note: Ensure that the fuel shutoff solenoid is latched in the RUN position. To latch the fuel
