Hurd window operator

Question

I am trying to replace what looks like a Hurd casement window operator. The photo shows a left opening window that works fine but I have 2 right side opening operators that need replacing. I am wondering if either the 39-035 or 39-317 would be the correct replacement. The outside dimensions of the cover is the same as the 39-317. The length of the arm from the hinge to the hole of the window attachment is 3 1/2".

Hey there. In my opinion, I honestly do not think either of those will work. The 39-317 is close, but your link arm is mounted above the gear arm. With that detail in mind, please visit both our 39-387 and 39-388 operators. I believe you will find these match more closely.
