crank mechanisms for casement windows

Question

I'm trying to identify the parts needed to replace the opening mechanisms fore these windows. Some will need need replacement of the tracks under the window (where the opening arm/wheel fits into), but I do not have a picture of the track.

Hello,

The operator shown in your photos reminds me of the 39-031 and 39-032 at first glance but keep in mind that there are similar operators in other sizes. Take a look and compare the dimensions below to yours, paying close attention to the length of the shorter link arm. If you notice any discrepancies, let us know and we can go from there. Also, please note that both operators are compatible with the 39-107FK handle and cover kit, as well as the 39-505 track. Thank you!
