5200 old style Saginaw Steering Motor

In my 5200 I have the old style steering I believe it is commonly referred to as a Saginaw system. Does anyone know if the steering motor (valve under the steering wheel) is the same used in the Oliver tractors such as an 1850?

My box seems fine for now, the column is my only real problem it is all loose and I can't get it tight for some reason.... I was going to hunt down up a replacement to keep as a reserve and I noticed an Oliver unit at the local salvage yard which looked like it was identical. I don't know that though. I think the Oliver unit came from an 1850.

My brother had one go bad on a 5200 he had, he used one from a Oliver but it wasn't a perfect fit.

Could be wrong, but this motor was a ford design that did not work out so well. Used on 5200 and 7200. Possible the 4200, but I havent owned one of those. Insides were "married" parts and could not be changed out. Was able to modify(bend) the torque sensor on them to help fix the left turn problem.

Well maybe my best course of action is to do what I had originally planned... a permanent fix. Replace the whole steering motor with a Char Lynn unit, new column and new hoses from the hard lines to the new steering motor.

Will be much more expensive but perhaps it is time to cut bait.

Does anyone know what the difference was between these Saginaw style motors in a 5200/7200 versus one that was OEM to a larger 8000 or 9000? Appear the same. Maybe not.

again, its not a saginaw, its a ford design on the 5200/7200....

That's fine just know I am not making it up. Is that the correct terminology? Personally I don't care, but arguing with me about it is a fools errand. I don't know. For sure. I was a kid when these things were new.

The 2 units from All States AG listed in the picture below are 2 visually identical units. Per the NH parts store almost ALL the parts from the motor i have in my 5200 are identical to the 8000's motor below. Same scenario with e-bay listings for these motors all visually (closely) identical.

None of which is answering my question or bringing me anywhere closer to solving my problem. What I am going to do is pull one (not leaking) from an 8000 simply because it is blue and Oliver one is green, give the dude at the salvage yard $200 for it and move on. If the motor on my 5200 dies I should be able to fix it since almost all the parts interchange. Worth a shot for the money to me instead of trying to rig it with a completely different system.

Limbhanger,
One thing you might consider looking into
is the steering motor from an industrial
Ford. My buddy has hydrostatic steering in
his 545 loader tractor. Steering is
effortless even with a loaded bucket.
I have a 4200 with "I think" that same
steering motor. Mine works fine except I
have a dry bearing in the column somewhere
that I need to attend to someday.
Having read posts here about no parts for
them when I saw his I wondered if one
could be swapped into a 4200 if needed.
They at least are 20 years newer and parts
likely more available.
Ford probably sold more of them too so
more chance of finding a used one.
Whatever you find, please keep us updated
on your findings. There is a lot of good
info on these forums and it does get
searched out on google, etc.
Your info might help someone down the
road.
Thanks

Bill,
I was reading uo on that steering motor in
my 4200 recently. As I mentioned above I
have a dry bearing somewhere in the
column.
Looking at my FO-31 manual they either
called it a Saginaw unit or a Saginaw
style unit.
Left my book at a friends so can't look it
up now.
The big Blue book does not mention
Saginaw. Both manuals show overhaul and
repair of one.

yes, maybe so, but the one on the 7200 was specifically mentioned to be a ford design, with the "married" center... So... maybe I am wrong, but we pulled the manual, took it apart, as far as we could and then tweaked the torque blade (sensor) in the center as it was bent from doing only right turns... we could not get it fully back straight, but moved it enough that you had "fine' steering with it in its range, and then "major" steering when you turned beyond and the "paws" or slots for the major steering flow pick up. At least the 7200 would steer better to the right on fine steering inputs as before as I think about it,,, left turns had first fine steering then fast steering, right only had fast steering so it was very difficult to use till it got tweaked. and at that time there were no parts availible. Maybe I will try to research back to the manual that talked about it till the saginaw came along on "later" models, but did not think it included the 7200, 5200, or 4200. Or maybe it was a license deal.. who knows... I slept since then....Twas also also about the changes between the 5000/7000, getting the draft to work on the bigger models and other info in that manual iirc. I'll have to look.. Sorry if wrong.

ok,looking at the manual,, its the "torsion shaft" that gives you the fine steering correction... up to 9 degrees in each direction... and now that I think,,, some of these stripped out the splines on the top as the clamp was not tight between the box and the u-joint shaft... I remember a couple of those coming through and we drilled the shaft and pinned it.

Maybe someone will find the manual where it shows the words "married" as to each center section was custom fitted to the ford housing at the factory and could NOT be swapped out. Maybe just a bad dream?

well...looks like there was an early motor and a late motor on the 7200 so far.... the early was... the "Hydramotor", made by saginaw. and the later was a Ross motor. lest per one of my old books. Not seeing the one where the center was married to the outer... I will look some more. Memory says that it was Short lived due to problems and drove them to the later saginaw but again maybe a brain goof. I do remember the tilt mechanism had the torsion blade in it that took on the "permanent twist" that we were able to put in a vice and over a week of twisting was able to reverse most of the twist...
