Fenestra 1938 casement windows

A quick learner says:
Hello,

I am trying to find replacement crank operators for 1938 casement windows. My cranks mount straight down into the window frame. The arm is 9-1/2 inches. They are labeled Fenestra/Detroit.

The new Fenestra operator is now available for purchase, see part number 39-344. The 39-344 looks very close to your old Fenestra operator. Let me know if you need any other additional measurements of the 39-344 to make sure it will work as a replacement for your old Fenestra crank operator.

How do I disconnect the operator from the window.
I have Finestra windows, and I want to install a window A/C unit. If I can just disconnect the operator I can swing the window wide open and install the A/C unit.
Thanks!

For this operator, you should first look under the window sash. There should be a track into which the casement arm bearing slides. Looking at the track, see if there is a cut out or notch somewhere. Rotate the operator until the arm bearing lines up with the cut out. Then, lining up the end bearing with cut out you should be able to press down on the arm and release it from the track. The final step is simply unscrewing the casement body from the window sill.
A handy person from Virginia says:
I examined the track. There is no cutout or notch. (This window may date from the 1920's)
I could drill out the rivet that holds the arm to the window...
Any thoughts?
Thanks,
Alex

No, I would not drill out the end bearing on the arm. If you no not have that cut out, check to see if the track is held to the window sash with screws. That way you can unscrew track and not damage anything by drilling.
A handy person from Virginia says:
I inspected the track, and it looks like there are two rivets,one at each end, holding the track on to the window frame. The bottom ends of the (?) rivets, which are visible, are flat. The top ends are buried in the caulking which holds in the window panes.
My kingdom for a screw (or two)!
Any thoughts will be appreciated.

Before drilling out the rivets, try removing the operator from the window sill. Then, see if you can slide the arm one way or another. I can't believe Fenestra would want you to drill out the track to replace the operator, so I think it's worth playing around with a bit more.
