Ford 4000 filter set up question

[sony224422]

I have a loader and backhoe on my 4140 with a filter system. It has a bt216 filter, and I am wondering if the is a good filter to have? It seems small, but I can't locate specs on it. It is Tee'd into the return lines for the loader valve and the backhoe return line. My pump should put out around 20 gpm at around 2000 psi. My concern is that the filter is slowing down fluid or pressure. I have a weaker backhoe, it will dig but not how i would think it would. I can barely get it to pull or curl a cut of dirt.

I have not had a chance to put a gauge on it to see what psi I am getting, but I did flow check the pump over the summer. I ended up replacing the loader valve as it had a crack in the manifold somewhere. I am just curious if the filter could cause the hoe to have a weaker pressure out.

Most return line filters are only rated to 100 PSI or less usually less so that is not causing the backhoe to be weak.

Does the loader operate and lift properly?
If yes does the loader valve power beyond supply oil to the back hoe?
If yes does the loader valve get warm quickly if operating the hoe?
Reason for asking is the loader valve may have a power beyond sleeve that has O-ring on it isolating pressure from tank. If this O-ring fails over time is allows oil to by-pass to tank limiting power to the hoe but loader still operates normally.

I would suggest looking for a pressure gauge and fittings so that you can check your system at various points in the circuit.

I will have to play around more and feel the hoses. The loader valve is brand new with power beyond. I have not tried to lift a full bucket of dirt yet, but I will try that.

The hoe operates at a good speed moving, but seems weak in any digging action. I do need to get a gauge and see what I’m getting for psi, I am wondering if the relief is letting off early. Or maybe it’s possible the loader relief is set wrong too, i hadn’t considered that until now. It was supposed to be preset from new but I never thought to check that

What model loader and backhoe attachment? Any pictures?
Will the outriggers lift the rear of the tractor? Will the backhoe lift the rear of the tractor?

Here's the specs on your filter.

I've had to adjust the relief on every valve I've purchased from Surplus Center. If your valve has a built-in relief valve, it most likely needs adjusted.

I ordered a gauge, so hopefully I can get some numbers here.

Good to know about the relief, I got the valve from surplus center so I am hoping I just need to do a simple adjustment of it.

I am a little concerned because the filter seems to be for engine oil.. no mention of hydraulic fluid. From what I understand, and I could be wrong, but the viscosity of the hydraulic fluid I am using should be 10-30w (J20A)

The loader is the 712 ford loader and backhoe is a 723. Tractor is a 1964 ford 4140 HD gas. As for the outriggers, they will lift the rear of the tractor up, I will get a measurement to see how high it is. I know it lifts better than it did when I first got it, it would lift it about 2 inches off the ground. It will definitely get the rear wheels off the ground. I will also see if the bucket will lift the front off the ground

i got this from baldwin, but im not sure what it really means in terms of restrictions. it seems like it would be okay?

I was able to get my gauge set up. I am able to hit the 2000 psi relief setting with the controls bottomed out, so I’m thinking that the relief is operating correctly. My next step is to remove one of the lines to the cylinder and checking the pressure and seeing if the cylinder is leaking internally
