Remove (see figure 7-24). On ASK equipped generators, refer to Operator and Organizational Maintenance Manual and remove cover assembly. Remove retaining ring from camshaft center pin and slide cup off. Be sure to catch the ten flyballs that will fall out when cup is removed. b. Repair. Replace any flyballs that have flat spots or grooves. Replace cup if race surface is grooved or rough. The governor cup must be a free spinning fit on camshaft center pin, but should be replaced if excessively loose or wobbly. Check distance the center pin extends from the camshaft gear, this dis- tance must be 25/32 inch to give proper travel dis- tance for the cup (see figure 7-24). If it is less, the engine may race; if more, the cup will not hold the balls properly. If distance is too great, drive or press center pin in. If it is too small, replace pin; it cannot be removed without damaging the surface. If aluminum ball spacer openings are badly worn, re- place ball spacer. Remove self-locking flat head screws, install new screws, ball spacer and plate. c. Install. To install governor assembly, fill flyball recesses with grease MIL-G-23827 and install flyballs. Position governor cup on shaft and install retaining ring. On ASK equipped generators, refer to Operator and Organizational Maintenance Manual and replace ASK cover assembly. 7-16.
