SECTION 4
FLYWHEEL
Flywheel magnets must be of a particular strength in
order to run the ignition system. Weak magnets can
cause low ignition voltage which may affect engine
performance. Flywheels seldom go bad and would
only be replaced as a last resort in solving an ignition
problem.
Flywheel is under high torque and requires the
1
use of special tools for removal and installation.
Failure to use the specified tools can result in
injury or damage to the flywheel or coil plate
electrical components.
The force needed to loosen and tighten the
flywheel nut requires flywheel be removed and
installed with engine mounted and secured on an
engine stand.
Reference the following specification table for
flywheel Removal and Installation special tool
requirements.
