I think I'm missing a step in trying to disassemble this hub for an overhaul. I can't quite tell when or how I'm supposed to hit the hub (counterclockwise, I assume) and what it's supposed to loosen up. Here is a picture of the current state of the right side of the hub. I also took pictures of all the parts I've removed so far (in order) from the right side (top row) and the left side (bottom row). I also lifted out the driver (see here: http://www.karrot.org/ascotto/three_speed/exploded.html as 25) but I can't see how I can get the ball cage out of this part. Are those bearings not replacable?

Where am I supposed to hit the hub to remove the right-hand ball ring? Is it the notch that I'm pointing to with the screwdriver? Thanks for looking.
