First of all, thanks to the guys that responded to the previous post. I considered all the answers, and after much stress, and trying several methods, I drilled two 7/16" holes thru the pulley, just inside the shoulder. They came out such that I could insert bolts through the holes, and by grinding off the flat on one side of each nut, things just fit. Placed a deep socket from socket wrench set in the hole in pulley against the end of the crankshaft. A fairly heavy plate across the end of the socket, and tapped to fit the spacing of the bolts, made a makeshift puller. Took several steps, tightening bolts, removing, adding washers for spacers tightening, again.... That pulley stuck tight until the last possible fraction of an inch, but I finally got it off. It did what my 3 jaw puller just wouldn't do!

Now, more questions - tried to use the threaded hole in the crankshaft. Couldn't find but one bolt of the proper size and thread pitch to fit in my junkbox. It isn't 7/16, and it isn't 1/2. Diameter of bolt appears to be .471, and 13tpi. But my 1/2" NC die doesn't like the threads! What is it?

Now that I have the pulley off, I am looking forward to having to replace it. What's the best technique for getting it back on? If I could trust the threaded hole, and get proper threaded rod I might be able to use that to pull the pulley back on?

Ray, I had the same problem getting that pulley off my 49 Super A. I promised that I would never go through that again. Im a toolmaker by trade so I polished the bore on that pulley so it goes on with a light tap fit with a small babbit hammer. I also put a 1/4" set screw over the woodruff key so it never comes off. That way I dont have to worry about damaging the seal with a heated pulley or you wont damage anything by hammering the heck out of it.

I took a piece of pipe, larger than the crank, but that would fit inside the pulley, about 4 inches long, welded a plate over one end and used it as a driver, and drove the pulley pack on

I haven't replaced a pulley, but what others have said on this board is to put it in the oven, get it hot, run like crazy back to your shop and tap it on before it cools.

won't heat destroy the seal?

I don't remember the temperature, that was a concern. But, at least a couple of people have done it -- not an exact science.

I'd just drive it on with my handy dandy 4lb sledge. But then I'm pretty dumb about these things.
