5.
Install the flywheel (5) ensuring that it is not twisted during the
installation.
NOTE!
In the case of improper installation of the flywheel,
the magnets of the magnet carrier (e.g. for engines
with alternator) can be damaged. The alternator
does not function correctly if the magnets are
damaged.
6.
After the installation of the flywheel, check without fail that the
key (arrow) is seated in the keyway of the crankshaft before
screwing on the flywheel nut.
NOTE!
In the case of improper mounting of the flywheel,
the key can fall out of the crankshaft keyway. This
results in the flywheel not being properly fixed. Due
to the missing key, the flywheel nut can slacken
when starting the engine. This results in the
crankshaft and the flywheel being severely
damaged.
