OK! So I tried Heat,penetrating oil, big hammer, 5 ton gear puller. Didn't work. So, I made a frame to go behind the hub and a frame to go in front of a 17.5 ton powerpak hooked together with 5/8"threaded rod. Didn't work. So! I cut the nut off the center of the frame, welded on a couple plates in place of the nut, welded short pipe inside the square tubing to add support. And used a 20 ton jack?. Didn?t work! So! I welded another plate to the other plates, cut some 4? channel iron to fit around the plates. Welded all into place. On the other end, I added thick angle iron welded into place, and a 50 ton jack. That did the job.
