Hello,

Our built in 1992 cottage casement window mechanisms are failing. Of the 14 windows that open, 5 do not work at all anymore, all of them from the screw mechanism failing (the arms still seem to function well).

I can only find one number, 30751, on these clearly marked Entry Guard Truth mechanisms, they are probably the same on all 12 windows.

At this point, only the right hand (as seen from inside the house) screws have failed, the arms all seem to be working as expected.

Obviously, I need to buy replacement screw mechanisms for all 5 broken windows but I wonder if its worth it to replace all of them due to their age. Please advise.

Hello,

It looks like the worm gear that secures the handle to the operator base has failed, which, unfortunately, means that the entire assembly will need to be replaced. I would recommend starting by comparing the dimensions of the 39-333 and 39-334 to your assemblies, paying close attention to the length of the shorter link arm shown below.

It looks like you may also need new hinges. If so, see the 36-048. Thank you!
