Assuming I can make some sort of flat puller foot with a slot for the wire, what do I push against? If i put the nut on the shaft and keep it flush with the end of the shaft, that will allow the wheel to move maybe 1/4" or so. The problem is the nut doesn't allow me to put the pulling bolts in the holes. I thought I had another nut (ordered a 13/16-20 jam nut) but it was too small. It must be 7/8-20 or so. If I can find one of those I could grind notches for the bolts.
If i don't use a nut, I'm afraid I'll mess up the end of the shaft. I really don't want to do that.
