8-1/4 bearing pre load tool

Another option, for us labor intensive types. A short piece of this Speedy Metals 1-7/16" 12L14 Steel Hexagon grind and file .010 off each side, drill the center and tap 3/8-16 6 threads deep. Run in a long piece of the cheapest 3/8-16 all thread you can find and jam nut it down, jam nut with sleeve nut on opposite end. Make two and hang a 9/16 reversible gear wrench off of each end while you are setting everything up. Or maybe just get someone else to work on it...:lol:
