    How to remove cartridge bearings from a headset?

    I just installed a FSA Orbit Extreme Pro headset on a new frame. However, the bottom cup didnít go all the way and now I would need to remove the lower cartridge bearing. It seem to have stuck.

    I can easily remove the upper one just with using my fingers. I tried pulling out the lower cartridge bearing with a tier lever (big mistake). The bearing split in half, half of it is still in the bearing cub.

    So my question is: would be the correct way of removing cartridge bearing form a FSA headset?

    Could you use a socket (whose outside diameter is slightly smaller than the inner diameter of the head tube) and use that to tap out the lower cup?

    Why didn't the cup go all the way in? And why did that prompt you to have to remove the bearings from the cups? From the description, it sounds like the bearings are pressed into the cups.

    You were pressing the lower-cup in with the bearings in place? In went crooked and the cup is probably crushed and binding on the cartridge... well it was? now you have only the upper race of the cartridge bearing left in place?

    Some headsets (Chris King for certain) have the cartridge bearings pressed or crimped into the cups and they aren't removable. The headset press must use inserts or washers large enough to press only on the edges of the cups.

    I have an FSP Pig DH Pro headset that was removed from an older bike and it seems to have the upper bearing cartridge that is hand removable but the lower bearing cartridge is permanantly pressed into the cup.
