help with balance

Question

I have a Spring Balance with stam 30 D S 40
I'm very mechanically inclined and an electrical contractor.
It is 31" metal to metal The shoe (bottom) is 1/2" wide about 15/16 - 1" from curve to the front flanf and the front flange is 15/16" also
The track is 9/16 to 5/8 Closer to 9/16" widetop shoe 1" wide.

I made need to replace most of them in the house. However, there is no "Take Out Clip". If there is, it is below the lower window. It is single hung, non tilt impact window. There is a small screw on top of the lower sash

I researched replacing the balance springs and would appear easy enough, except that I cannot get to the take out clips. I was told there is a tool to assist loosen the tension before removing the screw on top?? I'll attach pictures.

I want to replace them all. Alsom the felt peices that came in the tracks when we first purchased them all got stuck down when the window was raised. Wife ended up cutting alot of them out. I want to make these work smooth for her

Thanks for posting! I think this is a Pan Am window. I also believe the balance resembles our S377-31, though with that spring it will have to be custom made. I'll go ahead and email you a purchase link and price quote for your review.

As for the top sash guides, see our 18-042. I also think the take out clip would be our 16-023. See if you can move this take out clip further up the window channel, or two squares holes where it would snap into.
