Reassembly
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 overstressed and damaged when the
hex flange screw is torqued to specifications.
NOTE: Always use a flywheel strap wrench or
holding tool to hold the flywheel when
tightening the flywheel fastener. Do not use
any type of bar or wedge to hold the
flywheel, as component damage and
personal injury could result.
1. Install the woodruff key into the keyway of the
crankshaft. Make sure that the key is properly
seated and parallel with the shaft. See Figure
11-67.
NOTE: Make sure the flywheel key is installed
properly in the keyway. The flywheel
can become cracked or damaged if the
key is improperly installed.

Crankshaft.
2. Thread the two starter mounting bolts into the
hub of flywheel, or use the flywheel puller to
serve as a "handle" and set the flywheel in place.
See Figure 11-68.
