The fit of the Koyo is just a bit more than a slip fit into the input shaft... nice. Should be able to pull it easily with a pilot bushing puller. Again I will lathe the mainshaft pilot to .75 inch.

There are probably some of the originals nos open roller cage bearing out there.

Has anyone removed the rear main shaft bearing -- new departure 3307--- with a bearing seperator and not destroyed it? Or does the inside snap ring on the shaft push the bearing off?
