Pretty common and I have the same issue on my B7200. Replace the seals ($20). The shoes probably need replaced as well. They are quite pricey. Dan

My thoughts are replace the damaged parts and go from there. Dan

And unlike Kub they clearly label the pressure, power beyond and tank ports on the valve 😇 Dan

Or most tractor supply stores. Dan

I am a big fan of replacing rather than trying to repair damaged cylinders. Have a look here. https://www.magisterhyd.com/product/2inch-bore-x-14inch-stroke-cross-tube-hydraulic-cylinder/ You need to compare retracted length in addition to cross tube fit. Bushing the cross tubes down is easy...

Makes sense - 1/4" is probably the only size they could get to fit the port spacing on the top of that valve. Dan

I have actually heard of them. Have you dfigured out what type coupler was used? Dan

Use a couple longer bolts and stack two of these. https://www.farmandfleet.com/products/070137-pioneer-hydraulic-coupler-break-away-clamp.html Dan

Follow tte loader control linkage to locate the valve The hose is a molded u turn connecting valve to trans case and is not large. Dan

The tank return will be obvious - look at the parts diagram. Its a low pressure molded hose - should be easy to cut it in half and insert a tee. Dan

Part numbers on the couplers? BTW - I see we are neighbors. Dan

I suggested a tee in the tank return on the loader valve. Short formed hose going into right side of transmission. Probably tight quarters in there. Transmission filler would be anothet possibility. Dan

The usual procecedure is to use your multimeter to check voltages along the conductor. If the main fuse is good you will show battery voltage on the load side of the fuse. Then you move up to the fuse box and check the feed there. Repeat until fault is found. Dan

You are welcome and happy splitting 😃 Dan

N = neutral PB = power beyond HPCO = high pressure carry over Different terms you will see/hear for the same thing - e.g. the pressure supply for connecting to a downstrram device. Dan

Its right if B is the backhoe supply. Here is my earlier diagram which might be a little more concise. Top is originsl connections and bottom is after adding the valve. Dan

That was a bit too much to follow but in general yes. The backhoe supply could easily come from third function - that is a common plumbing scheme. The third function is typically fed by the loader valve. The order of the valves in the power beyond "daisy chain" is not really important. Dan

OK - I found the B2650 installation instructions - here is teh diagram. You had it right in your earlier diageam. The hose with female coupler (4 in the diagram) is pressure return to the tractor 3pt. You do not need to to anything with it. The steel pipe with male coupler (2 in the diagram)...

In my NSHO the only port that should ever be called power beyond is the supply port. The other end should be called pressure return or something similar. I almost posted that Summit diagram. All you need to do is determine which of the two connections on the back of the tractor is the tractor...

Your tractor is plumbed properly. Kubota and many others throw the term "power beyond" around in a confusing and contradictory fashion. They fail to distinguish "from" and "to" in those references. The female coupler is the power beyond FROM the tractor TO the backhoe. The hose and male...
