The spiral should twist easily in and out. Seeing as how this was installed in 1997, I would put some white grease on the spiral to help it twist smoothly.
With someone helping you, you will need to drop the new balance in from the top of the sash, screw it in at the top, then let the spiral drop down. You will then raise the sash and, while someone holds the sash in the open position, spin the spiral up to the bottom of the sash. Finally, with our 75-004 tool, give the balance about three turns to charge it and lock it to the end into the sash clip. Let me know if you have any more questions. |

It looks like the clip that the balance is attached to is bent, preventing you from hooking on to the spiral end. Carefully bend back the clip towards the sash to reveal the balance end. I believe you have either our Series 400 or Series 500 depending on the diameter of the tube.
