Crossfire XR ball screws

I’m assembling my crossfire xr and have had no issues up until this point. I’m installing the X axis ball screw and there is a plastic ring with 3 small screws in it in each side of the ball nut where the felt washers will go. Do the felt washers but up against them or do I take those pieces off and the felt washers go in their place? I don’t see anything about them in the directions and want to confirm before installing them.
