Looks like you need a special tool that holds those two slots on the backing nut, to unscrew the mounting bolt from it. I've got the same derailleur with the same problem; just haven't got around to trying to fix it.

A Park Tool pin spanner will suffice unless the nut is really stuck on there, I've used one successfully for this exact job:
Pin Spanner | Park Tool
Pin Spanner | Park Tool

Bikes: yes
Just use a pin spanner, or the opened end of a needle nose pliers, to hold the bushing nut slots and turn the bolt on the front with a 6mm allen key.

Or, mount the 6mm hex in the vise, and work from the other end.
That's what I did when I made this tool from some scrap, about 15 minutes ago. (Love my Dremel!)
We'll call this Suntour Special Backing Nut Remover #cvman-RD-001
[MENTION=433911]primo123[/MENTION], let me know if you'd like to borrow it, I can mail it to you. But you (and I, too) should just get a pin spanner like everyone else says to.

NOW that I've got my mounting bolt removed, de-gunked, re-lubed and back to gather, can someone tell me how you're supposed to mount this thing tight enough to stay on a dropout RD hanger and still have it pivot around the mounting bolt? The only way I can see it working is with a backing nut on the other side of a thin claw hanger (which it came with). Is this one not designed to work on an integrated hanger?
