Install Flywheel
WARNING: Damaging Crankshaft and
Flywheel Can Cause Personal Injury!
Using improper procedures to install the flywheel can crack
or damage the crankshaft and/or flywheel. This not only
causes extensive engine damage, but can also cause personal
injury, since broken fragments could be thrown from the
engine. Always observe and use the following precautions
and procedures when installing the flywheel.
NOTE: Before installing the flywheel make sure the
crankshaft taper and flywheel hub are clean,
dry, and completely free of lubricants. The
presence of lubricants can cause the flywheel
to be over-stressed and damaged when the
flange screw is torqued to specifications.

NOTE: Make sure the flywheel key is installed
properly in the keyway. The flywheel can
become cracked or damaged if the key is not
installed properly.
1. Install the woodruff key into the keyway of the
crankshaft. Make sure that the key is properly
seated and parallel with taper of shaft.
