I've searched and found several helpful postings on fixing the loose steering in my super a - (180 degrees from 9:00 to 3:00 position before anything even thinks about moving.)
But I ran into a problem nobody else mentioned, and figured I'd post it here in case it can save anybody else some head scratching. I'll also throw in some random pictures so you can know what to expect if taking the steering box apart.
First of all, MOST of the looseness was due to the square drive not fitting tightly on the arm. (the picture with the 1/4 gear - it's hard to see that the shaft is square where it attaches to the arm, but it is. As square as it is, it's very loose. Some shims, folded at the top so they can't drop through - a new bolt - crank it all down - nice and tight now.
However in addition to the free play in the wheel, I also had what felt like loose wheels when going over bumps. My wheel bearings turned out to be fine, and everything else was perfectly tight - tie rods, etc.
I found a cracked weld on the part that attaches the front axle to the cast steering box.
There is a 1" steel rod that runs through a tube which itself runs straight through the main axle shaft (perpendicular to it).. The tube is welded in place.
Not only did one of the welds break on mine, but the tube itself sheared off at the broken weld.
Because the 1" steel shaft that runs through the tube is solid, the whole thing remained together, and fairly solid and hard to find.
The broken weld turned out to have a HUGE impact on my steering. The whole axle could rock back and forth 10-15 degrees in either direction, regardless of how tight the steering was.
I've included a picture of it, after I welded it (the only picture in the group of the axle - should be obvious) If it were attached, this would be looking straight up from the gound at the axle.
The weld is very thick because the break was very jagged, not a nice straight cut.
Note - to get the solid rod out, the bolts on the clamps on either side must come all the way out since they interfere with the rod to keep it from sliding forward or back. Then it pounds out fairly easily.
I hope this info /pictures can help somebody else someday.

Today's Featured Article - Two-Brush Generators - by Chris Pratt. Whether for product liability or because the aftermarket parts and labor business is lucrative, this concept is disturbingly prevalent. Fortunately when you step into your shop and make that jump 50 years back in time to work with your old tractor, this concept goes out the window. Even so, when it comes to the charging system, people quickly revert to this idea and start replacing the major components one at a time until it works. The reason you don't find any decals in your replacement set wit
