EDIT: Now that I look at it, its only 3/8ths of wiggle. So it might not be as big as an issue as I think.

When the blocks are loose, a chain tensioner pulls them against a fully taught chain.

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
