Well, I went back out. I had left the loader elevated and I had bungied the control lever in the 'release' position. Still elevated.

I played with it a bit. I even tried using the 3 pt. lift arm position control lever WHILE using the loader control lever believing that I may release the pressure this way. No go.

Then I noticed the 3 pt lift arms would not lift (with the loader control valve in neutral it should work...and had up to now). Hmmm I thought. Then I moved the loader control valve the the 'raise' position and the loader started to drop!

Well, I now knew that:

1: The hydraulic pressure was not being relieved previously. My original problem relates to not getting proper return. Since my 3 pt lift worked the new valve is my leading culprit!

2: The cylinders are confirmed to work both ways (No cylinder sticking issues causing my problem.

3: I now have a new problem since the pressure was now releasing BACKWARDS into the pressure line!


Currently, I cannot get the 3 pt lift arms to budge. And, I cannot get the loader to lift.

So, I fear I've damaged the pressure side of my hydraulics! How do I pinpoint the area? Pump? Relief valve? Other?

I'm learning fast but still have a long way to go. I certainly am not at the stage of hydraulic diagnostics yet. Any help would be appreciated.

At least the loader is lowered to a manageable level. But, now I can't move the back blade off the ground. (I can remove it to drive the tractor...lot of good that will do me!)

BTW, I added more hydraulic oil since with all this work it was a little low. But, no improvement or change. What happens if the oil gets too low?...Can I lose 'prime' of the pump? Could this be my new problem?

Paul.
