How do I remove sealed bearings from a bottom bracket?

As above.  I do not want to smash them out because I want to use them again, but I want to change my cranks.

with a big screwdriver/punch. its easier than you think.

Preston Pirate:
You can use a bearing puller, it fixes inside the inner race from the outside and would rest aagains the frame, you then use a screw thread to pull be bearing out of it's seat.


You'll be able to hire one from HSS or the like...

The other way is to hammer them out with a drift, but you run the risk of knackering the bearings with the harsh impact.

hooga1975:
nice one.  The bearings are now out and in one piece!
