Window will not retract

Question

I am not much of a handyman so hope I got enough pictures of value. It appears the gear inside the housing is warped and about half way closed just get a clicking sound but no more movement. I haven't figured out how to remove the arms from it.
The housing slides into the window.

Hello there. I believe this is the 39-239B Awning Operator. Please compare. We also carry a stainless steel version of this product, the 39-239C. Take a look and let me know if you have further questions.
