Hello, this is my first time posting here, so please bear with me if I break any of the unwritten rules.
Friend of mine has a B275, serial around 19k. 1955 or 56, something like that.
Anyways, he was driving it one day and it all of a sudden got to where it would not turn any further right than center.
So we took the side cover off the steering box and for whatever reason, it seems like the worm or pawl or whatever it is on the spline-end shaft that runs inside the steering box horizontally lost the correct timing with the screw end of the steering column shaft.
So as a cheap, temporary fix, we decided to just rotate the drop arm on the spline and fab up a new, shorter drag link. His range of motion will be reduced, but he'll at least be able to turn some in either direction.
The problem is that the original tie rod ends that the drag link threads onto are .625-19 threads per inch. Left hand thread for the rear (drop arm) and right hand thread for the front (steering arm).
My lathe will not turn 19 tpi and my chances of finding a .625-19 tpi LH tap are about 0.0% From what I can tell, the only thing mankind ever made with that particular thread is IH tractor steering parts!
Ok, so the seemingly simple solution would be to just replace the tie rod ends with new, non-IH parts. The joints on these are pretty worn out anyways. Something with a bit more common thread that, ideally, I could find hand taps to match.
So I've got the tie rod ends out and they are tapered fit into the steering arm and the drop arm. As close as I can measure with a set of calipers, the taper is about .125" per inch. Is that correct?
If so, what tractor or car would be a good match for replacement? From what little I've seen about it on the internet, Ford 9N steering tie rod ends are the same taper, but I'm really groping around on this. They do have a somewhat uncommon 11/16-18 thread but nowhere near as rare as the original International ones.
Any ideas?
