Anyone know anything about power steering on a backhoe?
I have a IH-3400A backhoe in decent condition but the power steering
has gone out. It started failing by working intermittently and now, it is completely gone. Yes, it has fluid. Sometimes the steering wheel will turn if you put a great about of force on it and the front tires will turn. At other times, the steering wheel will easily turn but not front wheel action. I do have a limited service manual for the machine showing the flow for the steering. I was thinking of getting a 0 to 4500 p.s.i. gauge and working down the line to see where I am not getting pressure but I don't know what I am doing. Any ideas that don't cost an arm and a leg? Thanks Joe |

Thanks Joe I presume this is full hydraulic steering i.e. no mechanical linkage, just a pair of hydraulic cylinders or a double ended cylinder operating the wheel linkage? There is essentially nothing that can go wrong on that end beyond a leaking or crushed cylinder. Attached to the steering wheel will be a hydraulic steering valve unit with four hydraulic connections, two to the steering cylinder(s), a hydraulic pressure supply and a return to the hydraulic tank. You can check for hydraulic pressure at the input, but 95% chance it's fine if the rest of the hydraulics on the machine are fine since they are normally all fed from the same pump. These steering valves are rather complex, but they aren't all that expensive, especially if they are newer. You may be able to buy a rebuild kit for the steering valve for $30-$50. Northern Tool and Surplus Center both list some hydraulic steering valves for around $450-$500. |

About the only thing I can say for sure is that, at least on cars, the power part is only "power assist" - it's fail-safe, in that if the pump goes out, you can still steer the car by way of the mechanical linkage, if you're stronger than Aunt Tillie. ;-) I'd look into that first - Pitman arm, idler arm, drag link, tie rods, that sort of thing, before I'd start troubleshooting the hydraulics. If it's entirely "steer-by-wire", so to speak, then, yeah, your plan is what I'd probably do. Intermittent pump, worn spool valve(s), leaky cylinder(s) and so on. Has it recently had any trauma where you could have a bent component? Good Luck! Rich |

Thanks allot, Pete.
No leaks or crushed cylinder. I will give it a better inspection. Pretty sure that it is a dual-action cylinder.

Anyone know anything about power steering on a backhoe?
I have almost the same model hoe with a complete set of manuals. Can
copy a few pages and email if you need. You're describing an O ring or backup ring failure in the stearing cylinder. If true, it should go back and forth nicely with front tires off ground. This is an easy repair. If that's not it, crack the hose line on each side of stearing cylinder. Oil should spurt when you try to turn - this is a poor man's pressure check. If you're not getting flow - hire a real mechanic. If you need more send your email request to karltownsendATembarqmail.com Karl |

Sometimes they use a double action, double rod (for equal displacement push/pull) cylinder, sometimes just two normal cylinders (the Deere 500C I used to have used two). It doesn't really matter since the end result is the same, and in either case there is almost no chance of the problem being there. The problem is almost certainly in the steering valve, could be a bit of crud that got to it and is sticking a valve, could be a torn / worn seal, whatever. I overhauled the steering valve on my old 500C with an inexpensive rebuild kit. That was an older style steering valve and while a bit of a pain it wasn't that bad. Your valve may be newer which may make it easier to deal with, or a new valve may be cheap enough to just replace it. If you can replace the valve at a reasonable cost that will get you running fastest. Also get a rebuild kit and rebuild the old valve at your leisure so you have it as a backup.

These are normally 100% "steer by hose" and normally run from the main hydraulic supply so if the rest of the machine is working properly the hydraulic pump is fine. Almost certainly it's an issue with the rather complex hydraulic steering valve. |

There is not likely to be a pressure regulator of the type you're thinking of either, this normally runs off the main hydraulic pump and these are normally closed center hydraulics with serious variable displacement pumps. |

That would fit the "sometimes the steering wheel freewheels", if it uses a single dual rod steering cylinder, however it would not fit at all with the "sometimes the steering wheel is very hard to turn". My bet is on the steering valve. If true, it should go back and forth nicely with front tires off ground. This is an easy repair.

Sometimes the steering wheel will turn if you put a great about of force on it and the front tires will turn. At other times, the steering wheel will easily turn but not front wheel action. It sounds just like what happened to my 1963 Fordson Super Major ( Ford 5000 ?? in USA ), steering would fail intermittently and the tractor would veer to the left. Full power steering, not power assisted. No motor running, no steering, steering wheel will just rotate. #1 son was driving on the road one time when it happened and he ran over a 90 kmh speed limit sign. Turned around and lifted it up again with the FEL. We replaced the steering actuator to no avail, it was not the problem. The hydraulic cylinder had intermittent weepage from one side to the other, which is why it always turned to the left. A seal kit fixed the problem or take the cylinder to a specialist if not sure you can do it yourself. That is your first check and should fix the problem. If you do need a new actuator, email me and I will look up where I got mine from, somewhere in Indiana I think, they were the least expensive worldwide, and excellent service, about Oz $450 delivered, $580 from local ripoff distributor with minimum 3 week delivery, 8 days from USA.

Great, Karl. What model do you have?
I have somewhat of a service manual. One section of this manual is GSS -1416 (REV. 3), printed at the bottom left of each page.

G'luck with that thinking. I had a '72 2WD Scout and everything I ever tried to buy for it was matched to the particular engine and transmission you had, by year and by model. sigh -- "I probably became a libertarian through exposure to tough-minded professors" James Buchanan, Armen Alchian, Milton Friedman "who encouraged me to think with my brain instead of my heart.

Anyone know anything about power steering on a backhoe?

I have almost the same model hoe with a complete set of manuals. Can copy a few pages and email if you need. You're describing an O ring or backup ring failure in the stearing cylinder. If true, it should go back and forth nicely with front tires off ground. This is an easy repair. If that's not it, crack the hose line on each side of stearing cylinder. Oil should spurt when you try to turn - this is a poor man's pressure check. If you're not getting flow - hire a real mechanic. If you need more send your email request to karltownsendATembarqmail.com Karl hello im hopping you still have this email address i was looking to see if someone can help me with the same problem as the guy on here but just a little different...... i drained the fluid out of all my tanks and now the power steering dont work and also the swing on the backhoe. i have a 70's model case IH 3400A everything else works but those tow things and it was working good before i drained the oil can you please help me my email is ilandrio at yahoo .com |
