Windwo Crank handle and window part attached to window

Hi Jeanne,

Thanks for writing in! It appears that the entire worm gear has been completely stripped from the operator. This is the part on the end of the crank with the spirals on it. It's job is to interact with the gears inside the operator to help the crank handle turn. Unfortunately, this is not something that is easily repairable without the proper machinery. With that said, you will need to replace the entire crank operator.

I am confident that we can supply you with the replacement you need, but I'll need to see photo of the entire operator to make the best possible recommendation. I am looking to see a photo the arm(s) and how to connect to the bottom of the swinging sash (window).

Please feel free to reach out with any questions you may have in the meantime.

Hi Jeannie,

The window handle box you are referring to is what I am referring to as the casement window operator. The pieces that connect to the bottom of the window are the arms of that operator. I was requesting to see the entire operator so that I can make an accurate recommendation.

The parts at the top of the window that help it to open and close are the hinges. They are separate from the operators.

Based on what I can see here, it appears that you may have an older style GU Operator. With that said, your existing operator has been discontinued but we do have a replacement solution that should work for you. 

You'll need to purchase the 39-316 Truth Dyad Operator along with the 39-114L Crank Handle. You may also need to replace the bracket on the bottom of the swinging window, which would be part 39-514. The opposite handed version for the operator is part 39-315 and the opposite handed bracket is part 39-513.

Take a look at the video below that describes the process for replacing the operator you have. Please feel free to reach out with any questions you may have.
