I had a bearing go on my main shaft and decided to replace the bearing with a ceramic one. After hammering away to get the new bearing in the block I assume their must be an easier way to change these things.

How do you get the old bearing out and replace it?

IT's what I do.

Usually apply some heat from a heat gun,should come right out.
and reverse to install new bearing. Heat the block up and new bearing should go right in. Might have to cool the new bearing a little first, and use a "touch" of green loctite (shaft retaining).

Heat it up in an oven. Even with heat they can still be a pain to get out

I heated my bearing blocks in the oven for 15 minutes or so and just tapped them on a wooden block and the bearings fell out. I'd put the new bearings in the freezer for an hour before hand and they just dropped in to the hot bearing blocks, you do have to be quick though as the bearings warm up fast!

I use a heat gun...same one used to apply monokote and other coverings. Takes just a couple seconds and the bearing will push out by hand.

Head again to put the bearings back in. I place the bearing into the hole for basic alignment, quickly flip the block over on a flat surface and give it a little slap and bearing pops right into place.

Very quick, very easy, and very little force needed. Oh, I also apply just a little green loctite to the outside of the bearing before I install it.
