Unscrew the three smaller screws on the back of the motor, and carefully pull away the circular black plastic cover (take care not to pull too hard or the sensor wires may be damaged).
With this cover pulled away from the motor, you can easily remove the bearing.

I have the plastic bit with the bearing in it having removed the three screws but the bearing seems pretty tightly glued/pressed in the hole for it. Obviously I can't push it out from the other side. No idea how to remove it, don't want to scratch the inside of the bearing as it is new and I am just replacing with ceramic for kicks, would be good to keep it as a spare.
There is only about 1mm sticking out very hard to get a grip on. Novak sell replacement bearings so there must be a way to do this. Any tips folks?
thanks
edit: its a novak ballistic
edit2: got it out. I tried acetone but didn't seem to make any difference (might have though). In the end I removed the rubber part and sunk the bearing cap and bearing in boiled water for a few minutes. Took it out and it came out with a bit of effort and leverage. So that's one way!

info from novak tech support
Hello,
The bearings are glued and pressed in using heat. You would have to bake the endbell in an oven on low temps to get the bearing out and back in! Be sure to wear proper safety protection such as gloves and safety glasses and proper tools that are rated for working with high temps when doing this. You have to use a high temp bearing glue when replacing the new bearing. If you are not an adult make sure you have adult to help you out.
