Re: Wheel bearing replacement
You can pound out the bearings after working the spacer off center a little. Use something with a nice square edge to seat against the inner race and then tap,tap, tap. As the bearing is moved out, the spacer will move more willingly and you'll be able to walk around the inner race to more evenly remove the bearing from the bore.
Tapping them in is a little more tricky. I tap around the outside race until it is seated flush with the bore, and then carefully tap all around the outside of the race with a square-nose punch to evenly seat the bearing. The manual says to squarely seat the right (brake lever/pedal) side first, then pout in the spacer and seat the other bearing. I don't bother with putting the bearings in the freezer (anymore), and I don't notice an advantage over a room temperature bearing during installation.
