Replacing the impeller..

Okay, so, my turbo is broken, some of the impellers are broken, and I want to change the impeller's wheel by myself but I don't know how to remove it.. I've tried. I removed the little bolt.. but what am I supposed to do next?

turbos have to be balanced, and you cant do that yourself. If you just stick a new wheel on, the turbo wont last long.
