Finding point of failure - diverter valve or FEL control valve

[Xfaxman]

There is no switching the diverter as far as I know, it happens automagically.

That is not a typical diverter valve that is used for switching between two hydraulic circuits.

Does it say "Flow Control" on it?

I believe it says "Flow-Divider Valve".

That is what I was thinking. I'm thinking that might be a adjustable priority valve. If so one will go to steering and the other should feed the fel and everything after that thru the PB port. I don't understand the red X between the loader valve in and out lines in the drawing..

I think it is a circuit symbol, but don't know why the FEL valve is ahead of the priorty/flow divider valve?

I think that once you put a gauge inline you may be having pump issues,

ljPlum,
Here is simple way to hook up a pressure gauge for checking out your system.

Ok, I got my pressure gauge hooked up, and I've learned a few things. First of all, I was under the assumption this tractor was a common sump, so I was checking the transmission for fluid level, which was fine. The hydraulic fluid, on the other hand, was probably over a gallon low. I went ahead and did a flush. Drained it, filled it up again, ran the hydraulics, drained it again, and filled it up. Once I got it primed, the 3 point started working just fine.

So where I'm at right now, is that the 3 pt and PS work, the FEL does not.

I got a gauge as recommended, and am including a picture of my setup. I have it hooked up on the pressure side of the FEL.

Under no load it is at 0psi. When I try to lift the loader it is around 500psi, but it does not lift. When I turn the steering wheel all the way to the left it shoots up to around 1500psi.

 

[Xfaxman]

One of the lift cylinder pistons may have come off of the rod.

What is the pressure when the bucket is curled up and down?

 

[ljplum12]

It's about 500psi on the bucket too. The bucket is not working great though. It's slow and doesn't stay in the up position.

Where is fel valve getting the feed from?
