Just reinforcing what Glen is explaining, the black end float cover has no role in the worm adjustment - it only keeps dust out.
The critical part is get the adjustment of the slotted "worm end float adjuster" tight enough to almost take out any lateral worm movement, but not so tight as to allow binding. There is usually one spot for each gear/worm combo that is just a bit tighter as you rotate that mount axis through 360 degrees, and you need enough play on the float to avoid any binding , even in the middle of winter in your coldest temps.
