This position is locked in when the faceplates are tightened.

If a WCD drive bearing block doesn't clamp the frame, it will not work well. This rigidity is key

Im not entirely sure what you mean by the first bit. But it sounds like you'd have them loose when you're putting the chains in and slide them around to get your tension, then tighten them down. Your first sentence made it sound like there is another tensioner somewhere, though.
