I finally found where/how to do this on the new site set-up. I was going to look for that 1650 1000 rpm shaft at the farm this weekend. I hadn't been there 5 minutes, fell and tore the rotator cuff in my RH shoulder. I'm left handed, but it makes using a mouse a pain. As I recall there was about 4" of shaft ahead of the bearing, them about 2" of splines.
