steering wheel spinning

[Anonymous-0]

we have an 880A david brown case tractor, and the steering wheel just started just spinning around with no grip or turning of front axles. Anyone have any idea what the problem could be, and how to fix?? Please help. and would be greatly appreciated, Thanks

Hydrostatic power steering?

Hydraulic assisted steering?

Manual steering?

Pick one and I will try to help you out.

I believe it's hydrostatic power steering.

i believe it is hydrostatic power steering. last night we literally, manually worked the front axles to drive it from back of the acreage, and every so often it seemed to connect to steering. does that make sense? i'm sorry i dont really know how to put into words. Thanks for understanding.

If there are cylinders on the axle, one could be bad causing the oil to bypass. Otherwise it is probly the stearing motor attached to the stearing wheel. Have had those go bad and just continue to turn in the past. Had that happen on a 7700 jd combine and had to spin the wheel to the left as fast as I could to get it to the edge of the field.

Assuming hydrostatic(Steering cylinder bolted on left side of frame, hoses from the bottom of steering column to steering cylinder, NO mechanical connection to the steering wheel, just hoses).

Is there any oil in the steering reservoir(round can hanging on the left side of motor outside of the hood)? 10W Hydraulic, ATF, Trans-hyd, 10W motor are all suitable fluids.

The hydrostatic ones are really robust systems, but not very common on an 880. Seen them leak, but never fail outright.

Could also be stripped splines where the column meets the Danfoss/orbitrol unit. Could a stripped key on the steering wheel.


A picture of the left side of your tractor would help immensely in identifying what you have.

I have never seen one, but if it is set up like a Case 2090, there is a tiny little universal joint at the bottom of the steering wheel shaft where it hooks to the steering pump on the firewall. Had it break apart twice in one year. Luckily it happened in the field at low speed. No steering when that happens.

I know this all sounds pretty crazy and don't know a thing
about tractors. Unable to even get steering wheel off. Yeah
the power steering resivoir is on left side and has plenty fluid.
Sometimes the steering will hang without turning wheels keep
trying to turn wheel to left sometimes will free up so to speak
then spin again. Please tell me its probably an easy fix.
Bought this tractor a year ago for 2500$ no sooner bought it
had to put in shop for new hydraulic pumps for lift, over
1500$ still doesn't work. Hope you can help me?! Thank you

Don't know how to do a picture on this thing either. Guess I'm
just not hip? Sorry

Nothing like a 2090

The lift still doesn't work after $1500 repair? I'd be ticked. Likely a stuck latch or bypass plunger in the selectamatic valve. Separate problem, but shouldn't be a terrible fix. Lots of lack of knowledge with the hydraulic system on these. Dirty watery oil and lack of filter changes causes havoc in the hydraulics.

Diagnosis from a million miles away: Sounds like the steering valve has went out. The part runs $350 at minimum for new. Would take me under an hour to change.

The above is best guess, nothing cheap or easy.

Where are you located?

PA, Too far to be much help.


My only other thought would be the power steering pump is only providing oil pressure intermittently, possibly sucking air due to an imploded filter(again a lack of maintenance over the last 40+ years). Diagnosing it would involve cracking the lines coming off it and checking pressure, should be 1150 psi if I remember correctly. A constant supply of even low/no pressure oil will still allow steering, just it will be much harder than normal. Air takes away the ability to steer manually.

Hard to diagnose this stuff without having hands on.

yep its me again. Sorry it took a while to come back to respond to anything/anyone. RGMartin in particular, had to babysit and it rained here for a few days didnt want to mess with tractor stuff. Sorry. Anyways we took off steering shaft thing, and that bearing thing that hooks to the worm?, was messed up went to salavage to get one, haven't put it back together yet with work and all. Anyway also on that hydraulic thing do you know if there is supposed to be some kind of cable or line that runs on the outside of the arm control thing? Also do you happen to know where i can copy for free a shop manual for that? Thank you Julie
