e. Install (see figure 7-21). (1) Pack the cavity between the two oil seal lips with grease per MIL-G-23827. (2) Tape keyway and sharp edges on crankshaft to protect the oil seal during installation. (3) Mount gear cover (6) on engine using new gasket (7), screws (1 and 4), lockwashers (2and 5), and flatwasher (3). Tighten mounting screws to speci- fied torque. See table 1-1. Before tightening screws, be sure stop pin is in governor hole. (4) Refer to Operator and Organizational Maintenance Manual and install starter lockout switch.

On ASK equipped generator refer to Operation and Organizational Maintenance Manual and remove ASK 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 ex- cessively loose or wobbly. Check distance the center pin extends from the camshaft gear, this distance must be 25/32 inch to give proper travel distance 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, replace ball spacer. (Cam- shaft must be removed for this. ) 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 cover assembly. 7-16. CAMSHAFT ASSEMBLY AND TAPPETS. a. Removal.

TM 5-6115-584-34 NAVFAC P-8-622-34 TO-35C2-3-456-2 TM-0568C-34 NOTE To remove and replace only the camshaft gear, it is not necessary to remove the engine from the generator. Utilize the camshaft/crankshaft gear puller ring on 2-5, in conjunction with a push-pull type puller to insure stabilization of the camshaft to remove the camshaft gear. Extreme care and diligence must be ex- ercised when driving the gear back onto the camshaft to insure not driving the camshaft through the back of the engine.
