How difficult is it to replace a flywheel on a Tecumseh vertical shaft

I'm presuming the gear teeth are integral to the flywheel and therefore
metal, unless they somehow add a ring around the outside with the teeth on
it. *(That would help explain how it could be damaged.)

I can go fetch the engine model number if need be though I think most of
these engines are very similar. *It's on a Lawn-Boy walk-behind mower.

* Loosen the flywheel nut, put a couple of levers under the flywheel
to pull it up, then smartly crack the top of the shaft with a (brass)
hammer, and the flywheel should pop off the taper. There are puler
tools available as well, but I've had just as good luck with the
hammer.

What other said, except it is MUCH easier to pry up while a second
person does the hammering on the end of the crankshaft, unless you
have 3 arms?
