Thanks so much for both the link and the photos! That last picture in the link is what I'm looking at also. I've drilled out the set screw and am further soaking the bolt in AeroKroil to see if I can get it loose before I have to break out the big heater. I have reason to believe the bolt is loose in the pump shaft, but frozen solid to the handle.
