press fitting

If you can, tap a hole in to the middle of the saft and use a piece of all thread and a washer to draw the part into place. An arbor press is the best. I personally don't like hydrulic presses because it takes the "feel" out of it. Remember if you are pressing a bearing into place only press/hit on the bearing race that is in contact to the surface it is being moved on. Example, if you are pressing a bearing onto a shaft press/hit on the inner race, if you are pressing a bearing into a pocket press/hit on the outter race. This keeps you from damaging the bearing. If you can't afford a press a great tool is a punch. It helps direct your hammer blows to where you want them.
