CD spinner hubs

[Robotnik]

I don't know if this is the correct term for it or not... I'm referring to
the part of a cd drive or cd player that the disc is held in place by
(either by gravity, or snaps).

Is there a way to remove these from the axle of the motor that spins the
disc? I have a cd drive that I'm taking apart...and I want to put a snap in
hub on it and remove the one that is currently on it.

I figure they are just press fitted.

Thanks

Nic
