Hi Dick.
Just a small suggestion. I remember having a similar problem. I
loosened up the set screws on a large pulley and no go. So my solution was
to get a large pulley puller. Oh man it was tough going getting it of the
shaft. When I finally got it off the shaft had two furrows in it. Somebody
way back must have had a loosening problem and put in backup setscrews
over the original ones. I had one of those forehead slapping moments. I
now remove the sets all the way and look at whats in the hole. Take a
look.
Peace and good luck.

Sorry you got caught by this ... it's a standard way machinists handle
setscrews that are meant to STAY in place. The second one acts to jam the
first one much like adding a second nut to a bolt does.
