Remove Flywheel
NOTE: Whenever possible, an impact wrench should
be used to loosen the flywheel retaining nut.
A flywheel strap wrench, or an approved
holding tool (see Section 2) may also be used
to hold the flywheel when loosening or
tightening the flywheel retaining nut.
Always use a puller to remove the flywheel
from the crankshaft. Do not strike the
flywheel or crankshaft as these parts could
become cracked or damaged.
NOTE: Some electric start flywheels require the
ignition module be taken off first, or
loosened, to remove the flywheel from
crankshaft. See Figure 9-46. Perform
"Remove Ignition Module" prior to Step 1 if
applicable.
