I have a NVR 4500 series casement window from 2005. I purchased a new 9.5" operator window crank assembly but my old one doesn't have the plastic bushing on the pivot, it's steel. Then I looked at just purchasing a new track for the bottom of the window and I don't see anything like the one I have. Here is a picture of the window sticker and crank assembly, could you please help? Thanks!

Can you show us the entire operator? That would help narrow down exactly what new tracks you might need. Many thanks.

This might be our 39-504. Go over the dimensions to see if it matches. Again, without seeing the casement window operator that uses this track, I can't be entirely certain, but this seems like a possible match. You can view the rest of our tracks for window operators here.
