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?
