Just a cautionary note: Amir shows disassembly of a front hub. On my Paramount rear hub, the right flange threads on, using the same thread set as the cog. The left is a press fit, so the spoke holes can be oriented properly. So, don't try pressure to remove flanges that have threading w/o getting real sure that there is a shoulder for the press fit. Unlikely, since one side or the other has to transmit torque, eh?

Did this by placing the hub with the axle vertical and pointing towards the ram of the press. The axle nuts and cones were loosened (but not removed) with the upper nut unscrewed to the end of the axle, opposite the ram. Machinist's parallels were placed under the upper flange for support.
Then the ram came down causing the cones and bearings to push the shell away from the flange.
Repeated for the other side.

No hot oil bath required.
This was so easy that I'm tempted to make my own 3 piece hubs. (hence my request for bearing races)
