use any tools to pry against gear cover when
removing flywheel.
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

GEAR COVER
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).
