So I have a BP, and I adopted a new motor on to it because the old one croaked. so today I went to put it into High gear and all I got was horrible grinding noises and the step pulley was jumping up off the dogs on the direct drive. I ended up taking the head apart, and I found some troubling things. The low gear shifter seems pretty worn, the dogs are beat up badly, the upper larger bearings with the large spring clip has blown out the place for the spring clip. also when I had split the head into the upper and lower sections, the spline for the spindle was very difficult to rotate, I don't know if this is normal but figured I would note it. The mill has been in high gear in the past, it sounded fairly bad so I think I have bad bearings somewhere, anyone know what bearings I need to replace?
