I guess this is broken but i am not sure. Do i just need to replace the spring or something else. Please let me know what part or parts i need and if i need to remove this from the window to give you more information.

If the spring is all that broke, then you can probably just replace that. However if your parts are too old then it may be safe to replace everything. See our 15-192 pivot shoe, Series 170 and Series 171 coil spring, and finally the 15-156 cover and 15-157 drum. The video below will explain how these parts come together.

I can't really say, unfortunately. If you have an identical window in this house that still has all its hardware intact, I would check that.

I took out the spring and there is and it looks like the number stamped is 336. I called your company and they said I needed to weigh the window. It weighs about 12 lbs. So can you tell me which spring I need.

If your old spring reads 336, then you need an S170-336.
