FLYWHEEL
Removing the flywheel is a relatively simple process,
but the following procedure must be followed to
avoid damage to the gear case and possible injury to
the operator.
1.
2.
3.
Turn the flywheel mounting screw outward about
two turns.
-1
Do
not remove the screw com-
pletely since it acts as a re-
strainer when the flywheel snaps loose. If the
flywheel is not held by the screw, the spring
action in the wheel will cause if to fly off with
great force which can cause injury to the
opera tor.
Install a puller on the flywheel.
Turn the puller capscrews in alternately, until the
wheel snaps loose
on
the shaft.
Do
not use a screwdriver orsim-
ilar fool or pry behind the
flywheel against the gear case. The gear case
cover
is
die-cast material and will break if undue
pressure is applied in this manner.
4.
Unscrew the pullerfrom the flywheel, removethe
flywheel mounting screw and washer, and pull
the flywheel off the shaft. Take care not to drop
the wheel. A bent or broken fin will destroy the
balance. Always use a steel key for mounting the
flywheel.
GEAR
COVER
After removing the mounting screws, tap the gear cover
gently with a soft faced hammer to loosen
it
(Figure
60).
Make certain flywheel key is removed from crankshaft
before removing gear cover.

When installing the gear cover, make sure that the pin
in the gear cover engages the nylon lined (smooth)
hole in the governor cup. Turn the governor cup
so
that the nylon lined hole is at the three o’clock posi-
tion. Useasmall amount of greasetoassist in holding
governor cup in position. The smooth side of the
governor yoke must ride against the governor cup.
Turn the governor arm and shaft clockwise as far as
possible and hold in this position until the gear cover
is installed flush against the crankcase. Be careful not
to damage the gear cover oil seal.
