Window Spring Replacement

Question

Could you please assist in identifying replacement springs for this window? Are the attached pictures enough to determine the required part? The window has a top and bottom pane. The pane is approximately 34.25" high. Do you have any videos on how to replace these springs? These springs are installed in a track on the sides of the window. There does not appear to be any wider openings in the track to allow removal of these springs. Is it common to have to cut the track wider in order to remove the spring? If you need any additional information, please let me know.

I appreciate your help.

Thanks for posting! Your coil housing appears to be assembled with the 15-087 Coil Housing Pivot and the 15-086 Tandem Coil Housing. I am confident these are the replacements you need, but be sure to double check the dimensions.

Both of these housings use the Series 180 Coil Balance. Since yours are stamped with a 7 and an 8, you'll need the S180-07 and S180-08 coil assemblies.

Regarding the removal of these balances, if your window does not already have cutouts, you will need to create them. Take a look at the video tutorial below for reference; the hardware shown differs but the process is the same.
