Position Tool (D) on the end so the notch end is facing upward. Hold the governor output servo so the clevis is pointing downward. Slide sleeve (74) down the clevis as far as possible. Do not force the sleeve. Slide the entire assembly into Tool (D) from the open side. Position the assembly so the flange with the large diameter on servo piston (75) rests on the top surface of Tool (D) .
Slide the 1U-7635 Clevis Driver (Tool (F) ) over the end of servo valve (76). Position the driver so the end with the smaller diameter is against the shoulder of servo valve (76). Press against the end of the driver until clevis (73) is removed from the governor output servo.
Remove sleeve (74), servo valve (76), O-ring seal (78) and tolerance ring (79) .
Inspect all parts for wear or for damage. If the parts are worn or damaged, use new parts for replacement.

Personal injury can result from being struck by parts propelled by a released spring force.Make sure to wear all necessary protective equipment.Follow the recommended procedure and use all recommended tooling to release the spring force.
Note: Spring (96) is compressed in order to achieve a 50 N (11 lb) preload.
If necessary, remove retaining ring (94), spring seat (95), and spring (96) from fuel ratio control valve (89) .Note: Do not remove the pin from fuel ratio control valve (89). The fuel ratio control valve and the valve body are serviced as one unit. Some fuel ratio control valves do not have a pin that joins the valve and the valve body. In this case, the valve and the valve body are serviced separately. Elimination of the pin in the fuel ratio control valve provides overfueling for easier starting. Refer to the Systems Operation, "Fuel Ratio Control (Types V, VI, and VII)" topic for more information on the fuel ratio control.Note: Inspect all parts of the governor upon disassembly.
