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.

7-15. GOVERNOR CUP.
a. Remove (see figure 7-24). 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.

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

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.
