To install the pilot bearing in the back of the crank, you have to first remove a ring. We did this by tack welding a piece of pipe to the ring and welding a nut inside the pipe so we could screw in a slide hammer. It came our real easy.
There are 2 types of pilot bearing you can use. A roller bearing p/n 53009180AB (shown in photo below) or a sleeve type p/n 4338876
