fwiw, I was able to slide my pulley on far enough after heating it up so that I could grab at least 3-4 crank threads to pull it on. Threaded rod is the safest bet though.
Nice to see the oven method mentioned. I have done this about a dozen times. Works like a charm. Y'all did make fun of me when I posted this a few years back though.
any more advice or tips would be great here i plan on doing this thursday or friday.

That's what you use if you need to pull it off again. You have to use a different type puller.
