need awning window crank replacement

A home owner from Chicago, IL says:
The crank on my awning window is broken. There are no markings on the crank but the window has some etching in the bottom left hand corner. It says IGMAC, IGCC CBA, LoE, Cardinal, CIG-3, 4-97. It is a scissor like crank with two arms. Any assistance you can provide me is greatly appreciated.

Good Morning,

Looks like you have the 39-083 operator. Your window bracket looks a little different than what I'm used to seeing. We used the bracket 39-170 on the window sash itself, but your window bracket might still work.
A home owner from North Carolina says:
I have the same hardware on my windows (just bought a new home), except that the previous owner has removed all of the handles from the cranks. I was able to replace all of the handles except for the ones on the cranks which were missing the actual piece that the crank handle attaches to. The piece that is cylindrical, with grooves in the edges for the handle to "grip"? Is it possible to replace this one piece of the mechanism, or will I have to remove all of the hardware and start from scratch on these particular windows?

It appears you have a damaged gear.

We recommend you remove the entire operator system and replace it.

When you have it removed, take a few photos of it and upload them so we can help you identify the correct replacement.
