Split arm cranck

Hi. The holes on the window sash have worn out and the screws no longer hold the sash and stud bracket in place, i.e., I can no longer open and close the window with the split arm crank and have to do it manually. What options do I have?

(1) Is it possible to use anchors inside the screw holes, something akin to the Snaptoggle anchors?
(2) should I consider replacing the whole split arm crank system with for example a dual arm crank + track system?

Thanks

Hello, thank you for your patience,

I had the same situation at my son's house. I can see you have the 39-546 sash bracket, the same one my son's window has. What I did to repair it was to use a screw like the 33-022 in that top hole into the lower rail on the window sash. When installing this screw make sure you will not be drilling into the glass. Use a flat blade screw driver to disconnect the sash bracket from the operator arm. You might need to hold the bracket with a set of pliers while disconnecting it. I also installed larger screws in the face mounted holes. You could try larger screws or possibly some type of anchors. Try using plastic anchors or a very short molly bolt. The type of molly bolts they use in hollow core doors. Lastly make sure your window is operating "smoothly". Try a spray lubricate or spray furniture polish to lubricate the tracks. Please let me know if you have any additional questions.
