Compound Rest Disassembly Question

I'm trying to take apart the compound on my 1945, 10" lathe for cleaning. I got it down to removing the compound screw. The manual shows a screw to remove the bushing, but I can not find a screw. There is a detent ball. I pushed it in and can't figure out how to remove the bushing. I see I have the same thing on carriage unit, on ine the cross feed bushing, which is what I'm taking apart next.

Any help appreciated.
