Hydraulic Valve Block ???

[mrcarnage2]

Hello,

Looking on installing a 3rd function diverter valve. All the video's I've seen are showing a different valve block setup. I have a kubota B3300SU my lines from the loader go into this valve body, I have labeled it the best I could. Does anyone know where the "power beyond" is on this setup? I also have a question about the 2 long plugs in the second picture. they both look to have internal snap rings. what are they for? Rear remote possibly???

Thanks for you answers in advance

Suggest you need the OM for your model loader. You do have a loader inztalled currently?

A third function would not plumb directly to hydraulic block. You could use power beyond port fom loader valve if equipped. Or you could tap into the bucket curl circuit and install a diverter valve which would split that flow into two circuits. Diverter can be electronic or manual.

I did a more involved system on my ford. The koyker valve did not have power beyond port. I installed a new two spool valve powered from hydraulic block, Used power beyond port from new valve to supply existing loader valve. Existing loader valve returned oil to tractor reservoir.

If you have rear remotes, that can power a loader 3rd function, but it is not as convenient as control at the loader valve. What task is anticipated for 3rd function? Grapple?

NIW can likely provide a better explanation.

I have an OM for the tractor and I have LA504 loader. Didn't know they make a seperate manual for the loader. I would've thought the OM for the tractor would give me this information since the valve body is part of the tractor. But if it does I can't find it.

I downloaded a copy of the LA504 OM. and it does not give this info either.

I planned on using it for a grapple, yes

You loader valve is probably very similar as the one on a 3150, pic and manual here
https://www.manualslib.com/manual/1076147/Kubota-Wsm-B2050.html?page=366#manual
Have a look to see if there is a hydraulic block on yours as pictured on the PB line. The other parts are part of the FEL valve spool detents I expect.
EDIT: If you go back a couple of pages all your pipes at the FEL valve are labeled in another pic.

This is exactly what I was looking for thanks!!!

Great, not sure if the rest of the manual will be of any/much help, I don't know how similar the two tractors are.
