 1700 steering problem

It seems my "power assisted" steering has left the building! (I have calius' to proove it!) I have changed the hydraulic fluid. PTO and 3 point lift still operate. No problem shifting.
What could be the problem? I have no idea how thw steering system works. Any assistance will be great.

Mike

P.S. There is a small leak at the base of the steering tube. I imagine this would have alot to do with it not operating. Is the answer to my problem is simply repairing the leak, why did the steering work for a year after the leak started?

If you had a leak and as a result now have an air-lock (too much fluid left the system), that may explain how the steering operated fine and now has quit. You may have to repair the leak and bleed the steering system.

 1700 steering problem

My Ford assisted PS does not have its own pump and is fed from a priority valve on the main pump. On this type of steering the assist is produced by pressure on one side or the other of the sector gear. The control unit is a collar around the steering shaft. Up and down movement of the steering shaft due to thrust on the ball nut operates the control. I guess you've adjusted the steering and the free-play is within tolerance (that adjustment on my Ford has to be done with the engine running). There's also the possibility that nothing is wrong with the PS but steering linkage is binding. I'd raise the wheels with the loader to see if the steering is still hard.

If it's this type of unit, the likely problems are 1) no feed from the priority valve 2) faulty relief valve in the control unit 3) faulty control unit and 4) blown seals in the sector. A small leak shouldn't completely stop the assist.

I wonder how it sounds when the tractor is sitting at slow idle and the steering wheel is turned? If the engine lugs a bit then the PS is creating some load. A 'hydraulics' sound could be the PS relief valve opening. If there's no change in sound or engine load I'd start with the priority valve or pump. If there's some change in sound I'd run a pressure test (My Ford relief valve is adjusted to 1000 psi but it takes a very expensive t-fitting for the test).

If the pressure is low the relief valve can be adjusted. If it won't bring the pressure up then replacing the relief spring and plunger might help. I think rebuilding the control valve and replacing seals else takes substantial tear down and then the entire system might as well be rebuilt.
