Pella window operator replacement needed

Question

I have three Pella casement operators that still "operate", I.e. smoothly move the window, but no longer move the window into the final closed and "weather sealed"  position.

Hi there!

Thanks for reaching out to us. It sounds like your operator is stripped. The 39-176 and 39-175 Pella assemblies come to mind. I believe these are what you need to repair your window but take a look at the specifications and let us know if you have any questions.
