You are correct ,the sashes are not removable. To adjust or remove a broken balance, you will first need to raise the sash and have someone hold it up for you. Then, with the sash up, hook the balance with our
75-004 tool (or a pair of needle nose pliers) and unhook it from the sash clip, which looks like our
17-025, then unwind it. Be careful if the balance is charged, as it could spin out on you!
After you unhook balance and unwind it, lower the sash and unscrew the balance at the top. Then, raise the sash again and pull the balance out from the bottom. To install a new balance, you would drop it from the top of the sash and reverse the process. When you have the charging tool on the balance, give it three or four clockwise turns to charge.
When this is done, try the window out. If the sash doesn't stay up, raise it and give it another two turns.
As for the hardware itself, I believe you have our
S400-30 3/8" non tilt balance with a green bearing, which can support sashes that weigh 14 through 26 pounds. The sash bracket that came is our
17-025, which would be impossible to reinstall, so use our
17-031 bracket. This can be installed on the bottom of sash with our
33-073 truss head screw.
