Unique 26-C-30 spring replacement

A home owner from North Port, Florida says:
Looking from inside home, this part is from the left side of the window. Appears the spring broke. I would need a replacement spring and a diagram of how it is installed. Also, would I need to remove the window to effect this replacement?

Thanks for your help.

I'm afraid these springs are not able to be replaced by themselves. You will need a new balance. Based on your pictures, I think our S389-27 could be what you need. You may also want the 2630 option for that, but you should weigh your sash just to confirm that this is correct.

As for replacement, watch the video below for how we recommend you do it.
