The new ring gear for my tractor flywheel should arrive today...

I've never done this. Pretty sure you just heat it and drop on. OK,
how hot? I know there's only one shot, f%^k up, and go buy another
ring gear. I'm planning to go round and round with the rose bud and
need a guide line like hot enough to smoke oil, etc. I got no way to
measure the temp. Surely, it don't need to go to red hot.
