Peachtree casement window crank

The interior cranking mechanism shown in the photo does not crank the casement window all the way back in. There are two arms that are attached to the window that this crank extends and retracts but the interior part appears to be worn out or broken. I have six windows that need this same repair.

Hello,

Your photos resemble the awning operators that we've related on this page. We would need you to open the window and show us the arms that move the sash to confirm if one of these options would work for your repair. Thank you!

Here is a photo of the type of mechanism we have that needs a new cranking part. The arms will move in and out if the crank itself is fixed or replaced.
Thanks for your help with this.
