Crank comes out

Hello,

We'd be happy to look into this for you but we'll need more information to get started. First, we'll need to see your operator fully removed from the window so that the arms that move the sash are fully visible. We'll also need to see a clear image of the bottom installation holes on the base to narrow down your options. Note that the distance between the mounting holes and the diameter of the hole at the end of the link arm are important dimensions to determine the correct replacement. Thank you!
