Brad, what do you have handy for a welder? I can walk you through building a puller if you're so inclined.
You need and extension nut, ready rod, some scrap mild strap, some small nuts and bolts, and an old lawnmower blade.
I have a decent little mig.
I could pick up a cheap 2-3 jaw puller, but I doubt the jaws can get behind the gear. It's very close to the case. Perhaps I can grind them down, and hopefully not break them off.
