Pella Crank window with Stripped gears

Hello,

We'd be happy to look into this for you but we would need you to gently push the window open so that the operator arms that move the sash are fully visible to compare to our inventory. Thank you!

Unfortunately, we will need to see the arms that move the sash to identify your operator, which is not visible while the window is closed. If there is another functional window in the house that uses the same hardware, we can use that for identification purposes. Keep in mind that you will ultimately need to be able to open the window that you're working on to replace the operator.

Thanks for getting back to us. Take a look and compare the specifications of the 39-175 and 39-176 Pella operators to your assembly. 

Unforutnately, the arms that attach the operator base to the window sash are not available separately since it is all one part. We apologize for the inconvenience.
