    Default Ford 9N 3-point problem

    The 3-point on my Ford 9N has continually weakened to the point that it lifts just a few inches. If I put the tractor in neutral and let it run it'll eventually lift maybe a foot. Any ideas of the problem and advice on the repair?

    Have you checked the oil level in the trannie? Does it matter how much weight is on the 3pt when you try to raise it? Does it hold when you shut the tractor off without moving the lift lever?

    Most failures to lift on those hydraulic systems are due to a leaking lift cylinder, a leaking supply tube from the pump to the cylinder, stuck open relief valve, a leaking pump side plate, or possibly the control valve not moving forward completely due to sticking conditions.

    Pull the side plate off the right hand side and start the enegine with the pump(pto) engaged. UNDER NO CIRCUMSTANCES PLACE YOUR HAND INTO THE HYDRAULIC COMPARTMENT WITH THE ENGINE RUNNING! Place the lift lever in the full up posiotion. Using a flashlight, look up under the lift cover at the lift cylinder for a leak. Anything more than a few drops is leak. using a mirror, look at the right front corner of the hydraulic compartment. You should see a metal tube running vertically. look for fluid squirting from a crack or streaming down the pipe from a blown o-ring seal on the lift cover. Next look at the pump. Is there fluid coming outof the joint beween the main body and the side plate? (leaking side plate gasket) Is there a lot of turbulence and noise coming from the where the "H" shaped control fork goes into the fluid?(Stuck open relief valve). Finally, shut down the engine. reach down in the fluid and feel for the "T" shaped control valve stem attached to the "H" shaped control fork. Push forward on the "T" shaped stem. Then pulll back. The total motion should be near 1 inch. Now push the control stem all the way forward ( this ets the cntol valve to lift) and start the tractor with the pto engagedand the lift lever full up . Does the lift rise? If it does the control valve is sticking.

    Do these checks and then get back with the results.
