parts necessary to operate properly

Question

The window crank spins and will not open the window. This is the visible part to the operator showing it as Truth 30905. What needs to be replaced to get the crank functioning properly? Is it just this part that needs to be replaced or are there other connected parts to it that need to be changed out as well?

How is the part identified as a right hand operator?

Hello,

Your operator resembles the 39-172. Review the dimensions below to ensure it matches up. It sounds like either the gears or spline may be damaged. In either case, the entire assembly would need to be replaced.

If needed, see the 39-114L. If your old stud bracket is undamaged you could reuse it; otherwise see the 39-546. Thanks for posting!
