Allis B steering

Is there a way to tighten up the steering on an 49' B steering box. I think it is a Ross steering box. Linkage from the steering arm forward is nice and tight. The play seems to be from the interaction of the teeth and threads in the box. Both the threads and teeth do not seem worn and no metal shavings etc in the grease. Have almost a 1/4 turn of the wheel each way before engagement of the wheels. There is a slotted screw on the right with hex nut but turning it really does nothing. Looking inside the box, I really cant even see what this does/interacts with. I should have some pics later this evening if nobody has figured it out by then! Thanks!
 
There is a part, that I have called the follower button, in the gearbox, which is moved through the worm gear, and has been the problem , which I have found. I bought a used gearbox, and it also was badly worn. I took my disassembled gear box, to a machine shop, where they built up the button with braze, and filed it down to smooth, this filled the groves in the worm gear, and removed the slop! Sorry, there is no easy answer.
 

The slotted screw is turned in, clockwise to push the sector shaft "button" onto the worm gear to take up the slack.
If the "button is worn out (as most are) I drill out the worn "button" and buy one for a John Deere M, Part # AM1515T, they call it a stud. The stud on the JD sector shaft is replaceable, and that's how it will be on your B after doing this.
You can also get Tracy Martin (on the other AC site) to make you a "button just like the JD part.
If you don't have the resources to do this modification you can buy a new sector shaft from Steiner, #ACS068 for $98.95.

Well, I figured it out. The old adage of take
it apart, study it and learn its function
worked. The slotted screw on passenger side
takes up the side to side slack of the steering
arm. The eccentric cone and screw takes up the
slack between the threads by rotating it
around. I left the shims on the steering column
alone. Must have been the original cosmoline in
the box. Cleaned that up and replaced with new
grease. Steering works great now, (possibly
better than my truck!). Maybe now I can shred
the pasture without worry of taking out my
neighbors fence! Thanks all!
