Adding one more reply to Fred's question -
For us removing the donut collar was very difficult. The set screws likely
had mangled some threads and this caused threads to seize / shear within
the collar when unscrewing it. Our collar appears to be stainless steel, so
definitely a difference from the brass/bronze Ed on Prime Interest says his
is. Eventually what did it was a very large pipe wrench hit with a very
large hammer (with help from Lee on this list). The pipe wrench scratched
up the collar a bit but there was no avoiding this as rubber padding
attempts didn't have enough grip.
Like Paul, removing the radial drive was also difficult. The 4 bolts were
seized but I was able to unthread 3 using a large ratchet with a DIY
breaker bar (pipe extension). The 4th bolt got rounded off at the bolt head
so I had to cut it off with a dremel. The rest was easier than Paul's
experience though, the two halves came apart with some hammering of a small
wedge.
