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

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.

Lift the front wheels off the ground and run it back and forth about
fifty times. Does it ever kink? I'm wondering if you're losing balls
or worm in your steering gear.

Is it making noise at all? Does the noise change when it binds? Do
the pressure lines torque when you force it to the locks?

Broken springs on the pressure regulator can cause this symptom, too,
by allowing most of the force to bypass.

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.

Pretty sure that it is a dual-action cylinder.

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.

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.

Oh, yeah. I've seen that type. Kinda like a power rack and pinion,

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.

An intermittent leak in the cylinder would fit with the "steering wheel
sometimes freewheels" symptom, but not the "steering wheel sometimes
very hard to turn" symptom.

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

Great, Karl. What model do you have?

3514, built in the late 60s. I'm bettin' all Internationals for this
time used the same steering unit.

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

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.
