UE CVD Damaged..ideas on repair?

[Rtsbasic]

Do you have any ideas on who might have made them? A friend of mine has the UE cvds with the strange hex's and mine are a lot lighter than them. They ride on some odd size bearings - 12x18x4 for the inner & 6x15x5 for the outer. The hubs that come with them are a quality peice and are lighter than the Integy's I had. Smoother too.

Thanks for the advice regarding heat, was just about to go do that as well. I'll put a hole in a scrap bit of metal and try pressing it back with my vice.
