That adjustment is good. It adjusts the lash of gears and I adjusted it, I even overtightened a little bit and still had the freeplay present. I took it apart for inspection and the only thing I found wrong with it was what appears to be excessive wear in the ball groves, no specs for that. I guess I need to get another box.
