6.
After the installation of the flywheel, check without fail that the
key 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.
7.
Screw on the flywheel nut as far as possible by hand.
NOTE!
In doing so, ensure that the machined flat side
(arrow) of the flywheel nut is facing the crankshaft.
8.
Screw two bolts (6) into the thread provided on the flywheel.
9.
Fix the flywheel with a suitable lever (e.g. tyre lever) (7).
10. Tighten the flywheel nut with a torque wrench (8) to
216 - 226 Nm.
11. Turn the flywheel by hand and examine for unobstructed
movement (must not jam).
