Your writing has piqued my curiosity, though I am in agreement with what
you say.

It has been a while, but my best memory is ring gear removal procedure
starts with " , , , grasp hacksaw" <G>.  IOW, I know of no way to remove
the ring gear intact.

This is where I am curious. Do others here have a method for ring gear
removal which preserves the gear?  This gets into heat treatment, and
the ability to heat the gear without spoiling the flywheel, if indeed
the latter is heat treated in the first place.  I just do not know.
Perhaps removal has been accomplished with a very powerful press.

At this point though, Chris, I agree simply fitting a new gear makes the
most sense

If this is a friend of yours, tell him that he does NOT want them to
turn the ring gear around on the flywheel.  

If the teeth are worn, he'd be much better off having a new ring gear
fitted (they aren't THAT expensive), and I seriously doubt that they'll
be able to get the old one off without ruining either the ring gear or
the flywheel.  They'd have to heat the ring gear WAY too much to get it
off.  (There's a reason that the method in the manual for removing the
ring gear is to break it.)

Maybe I'm overcautious, but it sounds like false economy and I hate
having to pull an engine twice because I tried to save a few bucks the
first time.
