Slop in a Super A Front-end

How far do you have to turn the steering wheel before the wheels respond? If about a quarter turn then it can probably be taken out by tightening up the link arm connections. If more than that then it may need bearings replaced in the steering gear box as well as some well worn or broken components in the link arms. The Super A I fixed up needed both as the steering wheel would turn about 3/4 of a turn before the wheels would respond. The parts can be found. I would be more concerned with making sure the steering gear box is not cracked, broken or welded. That is an area of weakness for those tractors if someone hit something solid with the front end.
 
Yes it can be good as new you just start at the tierods and work back thru the steering sector a little here and there and soon its like new again. Mite need bearings bushings and seals but they can be rebuilt.
 
Retcol: If it's tyrods you can see that, just turn the steering wheel, watch the tyrods and wheels. If there is end movement in the steering shaft then it has bad bearings. If the shaft is tight don't fix it.

If you see a cracked steering box, walk the other way. If someone used it that rough you don't want rest of the tractor anyhow. In all my 67 years, I've never seen a cracked steering box, block will break first.

Usually 90% of steering slop will occur in two woodruff keys on steering box vertical shaft. Within the box the half gear is keyed to shaft, outside on the bottom steering control arm is keyed to shaft. I've seen those two keys cause 1.5 turns of free travel on steering wheel, with all other items tight. So basically, if you can't see it happen, woodruff keys are the culpert.
