Crank want catch to retract/close window

A home owner from Denver, NC says:

I am trying to locate the problem which is preventing me to be able to close my window.
The crank, once put inside the crank box will allow me to open the window but when you want to close it the crank just turns, turns and turns it doesn't catch to the inside crank to allow it to come back.

The window crank box is 5"
The window is 21.5 X 21.5 and the window opens from the bottom
The crank with handle is 5"
The crank without handle is 1 & 5/8ths

I have been trying to find someone to help me with this but can't seem to find anyone so I am going to try and do what I can. Any help will be appreciated.

Thanks for posting, Lori. It looks like the bore on your operator is stripped out. See the screw part on the end of the handle? In the top picture, you're pointing to it and measure it as 1-5/8". Well, that's not supposed to come out! I'm afraid that you'll have to replace the whole operator unit.

I'd be happy to help you find a replacement, but I'll need to see more of the operator itself. If you can, please remove the operator from the window and take a few pictures of it separately. I need to see the whole thing. Let me know!

Thank you for your response. How do I remove the operator? I assume you are speaking about the white box?

The white box is just the base. We would also need to see the arms that extend in order to open the casement window.

To remove it, you would have to gently remove the wooden trim covering it with a prybar. If you aren't comfortable doing this just yet, then open the window as far as it can go and try to get a picture that shows both the arms and the base. It would be good to see the operator removed, but I should be able to manage with the latter method.

Hello and thank you again for your help with this.
After prying off the frame work to get to the base I believe I will need to replace the whole unit. It looks like it may be difficult to remove the arms from the white box and much easier to remove and replace as a unit?
I have provided pictures of numbers etc., which are located underneath the arms and white box.
pic 1: under white box = looks like a patent number
pic 2: what the arms look like
pic 3: arm
pic 4: verbage "truth"
pic 5: other arm = 3409

Thanks for your help

Thanks for the new images, Lori. I think you may have misunderstood me. You can't remove the arms from the operator. I just meant that I needed to see a clear picture of the base and arms together. You will have to replace the entire operator.

Now, we have a few possible replacements that you might want to consider. Check out our 39-015, 39-083, 39-140, and 39-143. Compare their dimensions to your operator and see which is closest.
