Pressing the bearings on is not a big deal and can easily be done yourself. I ended up buying an h-frame press from harbor freight because I do it so much. However, before I started using the press I probably pressed on a dozen or so bearings with nothing more then a block of wood to act as a cushion, a hammer, and a 2×4 with a hole cut in it.

You just put the bearing on by hand (it doesn’t fit on very far) then put the bearing on the 2×4 with a hole cut in it so that the hole is big enough to accept the shaft but too small for the bearing. Then using the block of wood as a cushion, hit the other end of the shaft. Takes a couple of minutes but your bearing will go on just fine.

Another option that is more delicate (but one I have never bothered to try since the above method always works fine) is to put the bearing ontop of a 100 watt light bulb and let it heat up. Once it is nice and hot, using gloves pick up the bearing and put it on the shaft. The heat should make the bearing expand enough to slip right on. Others have done this and reported good success. Just make sure you use a lightbulb and not a fire or torch.
