casement window crank screw missing

A quick learner from Stamford, CT says:
looking to identify the exact part that i need to replace here for this to work. the Andersen window is missing the little screw which sticks out and where the crank handle attaches to. Do i need to replace the whole operator mechanism or can i just get that little screw bit? in either case, please advise on which units/model numbers to purchase. thank you.

Good afternoon! It looks like the center gear bore has fallen out. I'm afraid this cannot be replaced; you will need a new operator. It's hard to tell exactly what you have but I recommend looking at our 39-095 and 39-151 for two possible replacements.
