(smoothest) hole in the governor cup. Turn the governor cup so that the
metal lined hole is at the 3 0' clock position. The smooth side of the gov-
ernor yoke must ride againstthe governor cup. Turn the governor arm
and shaft clockwise as far as possible andholdin this position until the
gear cover is installed flush against the crankcase. Be careful not to
damage the gear cover oil seal. Adjust the roll (stop) pin to protrude to
a point 3/4 inch from the cover's mounting surface. .
GOVERNOR CUP. - With the
gear cover removed, the governor cup
can be taken off after removing the snap ring from
the camshaft center pin. Catch the fly balls while sliding the cup off.
Replace with a new part, any fly ball
which is grooved or has a flat spot,
the ball spacer if its arms are worn
or otherwise damaged, and the gov-
ernor cup if the race surface is
grooved or rough. The governor
must be a free spinning fit on the
camshaft center pin, but without any
looseness or wobble.
When
installing the governor cup,
tilt the engine so the gear tsup, put
the flyballs in
place (equally spaced)
and ins tall the cup and snap ring on
the camshaft center pin.
This distance provides an in and out travel distance of 7/32"for the
governor cup, as illustrated. ' Hold the cup against the flybaUs . whe]).:
measuring. If the distance is less (the engine may race especially at
no load), remove the center pin and press a new. pin in only the required
amount.' Otherwise, grind off the hub of the cup as required. The cam-
. shaft center pin can not be pulled outward nor removed without damage.
If the center pin extends out too far, the cup will not hold the fly balls
properly.
TIMING GEARS. - If replacement of either the crankshaft.gear or the
camshaft gear becomes-necessary, install both gears
new, never one only. To remove the crankshaft gear; first remove
the snap ring, then insert two long *10-32 steel screws into the tapped
gear holes and tighten the screws alternately. As the screws are tight-
,-
ened, the screw ends will seat against the crankshaft shoulder and force
the gear off the end of the crankshaft.
