Window replacement hardware

Question

Hello,

I need help in identifying the following parts to be replaced on some old crank windows. The crank handle has a label of 40085 near the top and 22 near the bottom that you can see on one of the images. The crank has completely come out and I need to replace 8 of these handles. Also does anyone now how to reseat the crank. Whenever I tighten to close the window it starts to come out.
thank you

Looks like the worm gear stripped out of your operator. This damage can't be repaired in any way, unfortunately, so you're going to need an all new operator. Once the worm gear comes out it's not possible to put them back in.

Before we begin, I need you to remove the operator from the window and show me a clear, unobstructed photo of the complete mechanism. I have to see it all in one shot. I can then check our records for a good match.

Your handle is probably in perfectly fine condition and can be reused.
