FLYWHEEL (Fig. 31, Fig. 32)
Loosen the flywheel nut with a 1-3/8" open end or
box wrench as shown in Fig. 31. Do not remove the
flywheel nut, but unscrew it about two or three turns.
The flywheel is mounted to a taper on the crankshaft.
Take a firm hold on the flywheel fins, pull outward
and at the same time strike the end of the flywheel
nut with a babbitt hammer. See Fig. 32. The flywheel
will slide off the taper of the crankshaft and can be
removed after the flywheel nut is removed. Striking
the end of the flywheel nut instead of directly on the
crankshaft will prevent serious damage to the threads
at the end of the shaft. Also, do not use a hard hammer
as it may ruin the crankshaft and bearings.
In reassemble be sum the crankshaft Japer and flywheel bore arc
clean and free from oil. Also be sure the Woodruffkey is in position
on the shaft and that the keyway in the flywheel is lined up accurately
with the key. After mounting; seat flywheel on crankshaft taper by
slipping a piece of pipe over the end of the crankshaft and against the
hub of the flywheel, and striking the end of the pipe a sharp blow with
a hammer. Install lockwasher, applyLoctite 271 tocrankshaft threads,
install flywheel nut and torque 95 to 110 foot pounds.
