Oliver 1850 steering orbit motor

[super99]

The old Saginaw steering unit is nearing it's last days. A long time ago I read somewhere that a guy took the steering motor from a MF 510 and put it in his Oliver tractor. I have a MF 550 setting here that needs to go to scrap, wondering if if would work in my 1850. If I remember correctly, the steering shaft from the Oliver fit on the orbit motor from the MF. Am I dreaming??

You're not dreaming. I think they're the same. Have you ever had the column off any of yours to replace a seal or anything? I believe all you'll have to do is take the shafts off both and put your extendable shaft back on the combine steering motor. I don't know if the one off the Massey will have holes for three position tilt or only two like the 1600-1900 had.

I just got thinking, I don't know for sure if the one in your 550 is the same as a 510 or not. It might be like the difference between an 1850 and an 1855. Still worth pursuing.

Steering motors from 525-545 combines are the same as well. Or you can buy a Char-Lynn column and tilt bracket out of a 1655 or 2-70 and do the upgrade.

Thanks, I'm retired on a limited income. Just trying to do this without spending anymore than I have to. Since I have the 550, when it warms up I'm going to try it.

Let us know if it works so we'll have it for future reference. Like I said, I'm about positive on the 510, but not the 550. I wouldn't think they would have gone to a closed center system on a combine at that time, but you never know. You could go to agcopartsbooks and see if the 510 and 550 use the same steering motor I guess.

Tried that, no pictures came up to look for part number

When you say ' nearing it's last days' , what exactly is occurring that you don't like? Leaks? Steering harder?

In my years in the heavy equipment industry, orbitrol , or derivatives thereof, are used all across the board in all sorts of ag and industrial equipment.

I have never seen one just plain wore out...leaking, yes, many times, but nothing that couldn't be solved with $20 worth of parts.

I haven't been close to an 1850 for many years, but i thought they had a external cylinder for steering. Is possible to bypass internally without external leaks.

I would run some pressure checks and make sure the pump is up to snuff before replacing parts based on guesses.

Those units were quirky, but you check out steering cylinder under radiator sometimes blow orings inside

There are no hard parts available for Saginaw steering motors anymore. Once they get to the point where you have to constantly keep turning the wheel to stay straight there is no fix to them short of finding a machine shop with the capability to custom make parts. It’s a well known common problem on the 00 and 50 series. The only practical fix is to find one that doesn’t wander which is easier said than done, or get the parts to do a Char-Lynn conversion.

What goes wrong in there? What part needs to be made?

The machined tolerances open up to the point that oil can just bypass right through the steering motor causing drift. All of the sealing is done hydrostatically through tight tolerances. Doesn’t take much wear on the housing or orbital assembly to loose that seal.

Off topic here. Super 99, I was watching some utube Oliver videos today by "that OIiver guy". That is you isn't it? In the 50 series video you were asking for any information about the origin of a 2150 belonging to a friend of yours. The video was from a few years ago, and I don't know if you're still interested, if that was you.

No, not me but I have been accused of being Chris. I took it as a compliment. Chris
