FLYWHEEL GEAR COVER
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. Turn the flywheel mounting screw outward about
two turns.
DO not remove the screw com-
pletely since it acts as a restrainer
when the flysheel snaps loose. If the flywheel is
not held by the screw, the spring action in the
wheel will cause n to fly off with great force which
can cause injury to the operator.
2. Install a puller bar on the flywheel (Figure 8).

similar tool or pry behind the
DO not use a screwdriver or
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 puller from the flywheel, remove the
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.
After removing the mounting screws, tap the gear cover
gently with a
soft faced hammer to loosen it.
When installing the gear cover, make sure the pin in the
gear cover engages the nylon lined (smooth) hole in the
governor cup. Turn the governor cup
so the nylon lined
hole is at the three o’clock position.
Use a small amount
of
grease to assist 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 (Figure 9).
