I need help with replacing a Kolbe & Kolbe window crank assembly. The gears are not engaging and the interior components keep coming unscrewed when trying to open or close the window.I just need the internal working mechanism as the arm and handle are fine.

Thank you.

Looks like you need a new operator. Once that worn gear comes out, there's no repairing it. We can help, but I would like a clearer picture of the complete operator. I can somewhat see it in your second picture, but I'm not sure what it is.

I have attached additional photos of this window hopefully capturing the operator. The arm is approximately 8" - 9" long as it connects with the mechanism.

I have also added a couple of pictures of the "spring pins" that hold the screens in place. Not sure if you have these as well.

Thanks for all your help.

It's still a little tricky to make out, but I think you have something like our 39-031 and 39-032. Carefully go over our pictures and dimensions to confirm. For the screen pins, I would recommend either our 70-009 or 70-008, depending on your size.
