I'm trying to disassemble the cylinder on my JD model 90 loader to replace the seals. So far, I cannot figure how to get it apart and wonder if I need a special tool. A picture is attached, and when I put a wrench on Ring A and turn, both Ring A and Ring B turn together and all it does is rotate those parts in the cylinder. Based on the threads shown in the picture, Ring B is screwed into Ring A (or vice versa). Without ruining the threads, how do you hold one ring still, while turning the other?
