Broken part

Question

Looking for a retainer nut that holds the worm gear of the window housing. Window is a Marvin crank out 45003 truth manufacturer. My house was built in 1990 and the window is in the basement.
Is there a replacement nut that I can get?
Thank you
Arlene

Hi Arlene,

The worm gear is not sold separately from the window operator, so you'll need to replace the entire mechanism to repair the window.

Your window operator reminds me of the 39-015 Roto Gear Window Crank. To determine if this is the correct replacement match, carefully look over the specifications and compare them.

The compatible accessories can be found below this thread.
