Inside part of window crank stripped

Helly,

The internal gears of an operator, for the most part, can't be replaced on their own. If you could send us a picture of the operator, including the metal arms that move the window in and out, we'd be happy to recommend a replacement from our inventory. Thank you!

We appreciate the additional images but we will need to see the arms that move the window to identify a replacement. That means we'll need to see a picture with the window open as far as it will go so that the arms are visible or with the operator completely removed. Thank you!

Perfect. Take a look at the three different sized operators I related for you and see which one matches the length of the metal arms in your photo. Thank you!
