Hi Bill: I tryed your instructions from your answer to my orginal thread
posted 9/16/06 I have used a 1/2 inch drive air gun and a large puller, still
cannot remove flywheel. Are their any other lockings devices on crank shaft
by the lock nut. Or do i just have to keep hammering on the puller to remove
flywheel. Bill am a retired heavy equiptment mechanic with 40 years in the
trade. Please advise Willie P.

If a small flywheel like that is hard to remove, either there is corrosion
on the shaft and flywheel taper, or the woodruff key has sheared and jammed
the flywheel against the crankshaft. Perhaps a judiciously applied torch to
the flywheel center may expand things enough to allow removal. The flywheel
and crank have a taper fit so you know what years of corrosion may do to
dissimilar metals. Go easy on the hammer blows as the force is absorbed by
the crankshaft journal and the aluminum crankcase. Good luck.

Another thing you might try is with the nut off, and I'm sure you've
already applied ample amounts of penetrating oil... is to take a
hammer, "soft blow" if possible, and close to the crank shaft, is to
tap lightly but firmly on the flywheel around the shaft several times..
in many cases, this seems to help to dislodge the grip of the
corosion. Do this repeatedly , then use the puller. if it doesn't work
the first time, then do it again. sometimes this takes a pit of
patience, but then again that corosion was patient to set in over the
years, too.

Like Bill said.

good luck
