Window and coil spring removal

Question

Hello;
I have a window with broken coil springs, and I am not sure how to remove the window to get at the coil springs. The window does not come out when set a a 90 degree angle, as it appears to be in a solid pivot coil. I have attached a few pictures that hopefully you can assist me with.
Thanks
Dave

Hey, Dave. Your pivot shoe looks like a match for our 15-087, which means you'll want our Series 180 coil spring. You'll want the stamp off the old spring to confirm the best option.

As for removing your sash, it can be a little tricky. You basically have to force one pivot shoe up so that the pivot bar can slip out of the cam on one side, and then the other. See the video below for an example of what I mean; the balance system shown here is different, but the method of removing the sash itself is exactly the same.
