Thanks for posting! I remember answering this a few days ago, yes, but I'm being told the old post had the wrong email address. I'm afraid your operator is damaged and cannot be repaired; that worm gear I see attached to the handle is not meant to come out. You will need an entirely new operator. We can help, but we need to see a picture of the operator out of the window.
All done. We received 4 and they fit perfectly, and I just ordered another 6 to complete replacement of operators for all the awning windows on our screened in porch in Rehoboth Beach, DE. For three years breaking cranks on operators were the bane of my beach existence, and I am happy to say that is all in the past! Thanks for your help!
