I'm afraid this corkscrew bore cannot be replaced or repaired. You will need a new operator. I'm just not sure what you have. Can you show me a picture of the complete operator out of the window?
Thank you! I'm afraid these new pictures only show the base, though. We need to see the whole operator out of the window. If you cannot remove it at this time, we would at least need you to open the window as far as it can go and show us a top-down picture of the whole thing.
Hi
So the best way is to measure the crank.
Do you have someone to install it?
Thanks
