JD 5410 steering problem

[ronstar123]

Yesterday the 5410 steering wheel started spinning. No tire movement. FEL & 3 point still work. Plenty of fluid, no leaks. Any ideas to point me in the right directio?

By "spinning" do you mean the steering wheel is turning on it's own or that when you manually turn the steering wheel the front wheels don't steer?

Steering wheel spins with no resistance and does nothing to move front tires

Sorry manually turn it nothing happens. Can’t drive it as it has no steering

2 wheel drive or 4 wheel drive? When my 2 wheel drive New Holland steering cylinder needed to be rebuilt it leaking was overlooked. It's under the tractor, you couldnt see it leaking in operation. The seals were gone. The New Holland had a separate pump and reservoir for the power steering from FEL&3point. The reservoir was empty. If it's a 4 wheel drive depending on whose axle they used it may be even harder to see leakage from the steering cylinder. Consult your manual or download one.

Hydraulic pump has two sections, one for hydraulic functions and one for power steering, the "key" that drives the power steering section could have sheared.

Or, possibly something could have happened to the piston in the power steering cylinder.

Or, the steering "valve" that the steering wheel is connected to could have somehow failed internally (that would be rare, I think).

I would start by verifying that the steering section of the hydraulic pump is working, not so easy to do without a flowmeter. Got a little repair shop or a buddy in the area that might have a hydraulic flowmeter?

You could start by disconnecting the discharge line at the pump the feeds the power steering and cranking the engine to see if there's any oil being pumped, don't let the engine start, though, or you'll have a BIG mess IF the pump is working.

Even if the pump delivers some oil at cranking speeds that doesn't necessarily mean it will be able to pump under pressure, though.

Just a few random thoughts without knowing what experience you have with such things and what tools or resources (buddy) you may have available.

No need to worry about the pump until you confirm the steering cylinder condition. You don't need any special tools for that. Just take one hose off the steering cylinder. Doesn't matter which one in this case. Take a line off and let it hang. Start the engine and turn the wheel to pressurize the cylinder on the opposite side. If oil comes out of the cylinder from the open port and the rod doesn't move, the piston seals are your problem.
