WHAT IS THE BEST METHOD FOR INSTALLING NEW CONE SCREWS?
Replace the nylon bushing (if any) at the same time a new cone screw is installed. Press the bushing into place and grease the cone screw nose to lubricate the bearing surface and threads to prevent rust. Tighten the cone screw into the bushing to seat it with firm, but not excessive pressure. Back it out one full turn. Re-set the cone screw with just enough pressure until “drag” is felt on the cone screw. Then tighten the locking jam nut and lock washer to hold in place. When replacing the rocker arm or graduated circle link cone screws, replace one screw at a time.
