Window Crank Mechanism

A handy person from Highland, MI says:
I have a mechanism that needs replacing (left and right sides). When closing the windows the pinion gear pushes out. I'm not sure if you can read it from the attached picture but it is a Truth mechanism. The wheel that the arm attaches to is a 30842L and the arm that comes off that is a L30841. The dimensions on mine are identical to both the ones shown on the 39-035, however the arm shape is different. The cover is identical to the 39-107 including the dimensions. My bay window is about 13" wide, so it is a small window.

Do you have anything that would serve as a replacement? I need a left and a right.

Thank you!

Mike

Hi, Mike.

Thank you for your patience during our busy season. Our 39-035 and 39-036 is our recommendation for the operator in your pictures. If the dimensions match up, you should be good to go! Our 39-107 cover is also compatible with these operators.
