IGNITION SYSTEM
Flywheel Operation
3. Remove the flywheel by pulling up on the edge of
flywheel while striking the flywheel nut with a soft
hammer. (See Figure 55.)
The flywheel is connected directly to the crankshaft
(secured by a flywheel key and nut) and turns at the
same speed as the crankshaft. Two permanent
magnets, imbedded in the flywheel, rotate past the coil
in the CD Pack to begin the generation of electricity.
Imbedded in the opposite side of the flywheel are steel
counterweights which offset the weight of the magnets.
These counterweights are not magnetic.
A flywheel key and keyway in the flywheel and
crankshaft are used to assure alignment during
assembly. The tapered fit of the flywheel and
crankshaft along with the torque of the bolt or nut
actually holds the parts together. The surfaces of both
tapers must be good to obtain a good friction fit. The
key is designed as a light duty part so that if the engine
stops rapidly, due to blade impact, the key will shear. If
the key were too hard and the impact occurred, the
more expensive flywheel could crack.
