Tried posting this earlier but it didn't show up. Segmented,adjustable fan belt failed. The moveable pulley half is locked in place because the lock bolt is frozen and corroded in place. Used TRIZOL, WD40, heat. I was going to use a solid, real fan belt I got from Yesterday's Tractors but see that the tractor design doesn't allow room for sliding the belt over the crank pulley. What's the best procedure for getting the moveable puley loose? Does it require grinding off the top of what is now a mostly destroyed set screw, drilling it out and trying to use another bolt?
