Before you go to much trouble looking for that "sleeve" to use for pressing, sort through your socket set!

  Gentlemen,

  Having been a Millwright many years ago one of the first things you learn is to never pound a bearing into place. Always press, never pound. Pounding causes microscopic flat spots on the balls, which leads to early failure. For the size bearings we are dealing with the drill press is a good choice. Another is to make a sleeve to go over the crankshaft and use your vise to press it into place. Always press on the inner race, never on the outer race as pressing on the outer will also cause flat spots when the bearing hits home and you put that little extra force on it to make sure it is all the way on. We need to take every precaution we can to make sure our bearings last as no one likes to change them any sooner than necessary. Hope this helps.
