Except for the shaft the steering arm presses on to, I have replaced every internal part with new Case parts - An NOS steering wheel shaft/worm, new sector, bearings and bushings. The taper bore of the steering arm, the shaft's taper, keys and keyways - everything is in great shape. It's all back together and there is about 1/3 turn of play in the steering. Lock the steering wheel to one side and go 1/3 turn the other way before the steering arm begins to move. The steering box casting shows no damage. What next?

then bearings are probably o k. on mine the arm moved vertically. top bearing was burnt up
the worm gear, on the steering wheel shaft, fits directly into the sector gear, which fits the rear of the pitman arm. hmm. only thing i can think of, is the worm gear secure on the steering wheel shaft?
maybe someone else will get involved.

Khouse made a good observation. He focused on the vertical shaft. The other component to be observed is the long steering wheel shaft, incorporating the worm. Look closely at this shaft while the slack is being removed by turning the steering wheel. It is best to look at this shaft close to the steering box so that you can see if it moves axially (lengthwise) while the steering wheel is being rotated back and forward through this one third rotation of slack. (Having a helper doing the steering wheel movements is a plus, so that you can focus on the shaft's axial movement.) If there is axial movement
EITHER the ball bearing on the end of the steering shaft is not tightly mounted
OR this ball bearing is not snug in the steering box; you may need to put shims (washers) under the big hex nut/cap that keeps this bearing in place in the steering box.

You are on track, although I must say that, considering the pitch of the worm, 1/16 of an inch is less than what I expected for 1/3 of a revolution of steering shaft (steering wheel) slack. Anyway, you should and will be able to eliminate this 1/16 of an inch, it is way too much. The slack will never be zero but eliminating the slop on the ball bearing mounting may bring the steering wheel slack down to an acceptable level.
