terry: The holes you mount implements on all those small Farmalls are coarse thread.

On your dad's Super A, there was a change about half way through production so the serial number or year would help. My SA is a 53 and it has a round tapered shaft with woodruff keys in steering control arm and the cog. If yours is that type fixing those key and keyways will help. I understand A and older SA had a square tapered shaft. That change probably occured around 1951, when they changed tyrods to the automotive type.

The other item you would need to acess is wear on the cog and worm. If worn those two are very expensive and hard to find a good one as well. I've heard prices all the way from $200. to $600. The bearings on the steering wheel shaft may need attention as well. If loose those should create end movement on that shaft.

I have fixed three of these, all the tapered round shaft. One had worn worm and cog, it still has the worn worm and cog. Most of the play in steering comes right from those woodruff keys. We found keyways out of shape on the shaft as well. We ground larger keys to fit tight in shaft. Since the keyways had become flared, we welded along each edge of key welding it to the shaft. We then did some grinding on the weld. We had these so cog and steering control arm had to be pressed on. In two of the cases we got it right on, while the other needs a bit more work. We looked at this from a point of view that shaft was toast anyhow. New was very expensive. This was in 1992 and you could still buy new parts then, but not cheap. 12 years ago and 2 of them still tight as new. The 3rd one my 130 is the one with worn cog and worm, but it also has some movement in the keys as well. When I say we, my friend and I felt this was worth a try, we have been quite happy with it. Time was our biggest expence.
