I had tried to take mine apart and tired all sorts of ways to get them apart but to no avail.......I ended up doing like 1badgts had done......except I used a sand blaster and got the rust off then spraying them with rustoleum primer (couple coats) then sprayed a couple coats of semi gloss rustoleum paint....of course I blew out the bearing area good and re-greased them. Worked just fine.
