B2620 hydraulic leak - what is this part?

[swnelson]

I bought a used B2620 tractor. It came with some vacant land I bought and it's the first tractor I've owned. I've used it a handful of times since then with a brush hog for clearing a bit, but not much else.

Noticed today that there is some sort of hydraulic leak for the back implement. When I raise it, fluid spurts out of this little cylinder attached with a mounting bracket. It kind of looks like it's coming out of the spot where the cylinder is welded to the bracket?

I can't figure out what this part is from the kubota illustrated parts thing. Is it maybe some aftermarket gadget? Like I said, almost no experience with tractors so don't know what I'm looking for, or what the name of this woul dbe.

did a backhoe come with the B2620?

the BH65 backhoe was an option that could be bought with the tractor. It is a removable backhoe that is easy to put on and off utilizing 4 attachment points . When the backhoe is attached that connection shown in the pic's are separated and attached to the hoe to provide the fluid flow for the backhoe. When hoe not attached the hoses get disconnected from the hoe and attached back as in your pic's to keep the hydralic flow circuit in place.

so the cyl you mention is a hydraulic coupling or maybe you mean the bracket with hardline attached that holds the "mess" in place. I had one years back that leaked from the hard line attached to the silver bracket that is mounted on orange frame. I ended up deleting the silver bracket and hard line and rigged the circuit without that section. Worked for many many years afterwards

So you need to find out if you have a loose/leaky fitting that can often be fixed by snugging them up or leak from the rubber hose which will need to be replaced or hard line leak which maybe can be repaired or replaced. Once you find leak solution will follow. In that area there are lots of fitting joints, the rubber hoses or the hard lines that the leak is coming from.

BTW just a safety caution.if your checking for the leak with your hand DON'T . use a piece of paper or something to see where it's spraying from. Hydralic oil under pressure can go through your skin etc:

boakley, you nailed it I think. Yes, the BH65 backhoe came with the B2620, so this makes a lot of sense.

The hardline is the part that is leaking I'm pretty sure. It's easy to see stuff spraying out from there.

The part number is 7K504-64850, looks like it's about $35 which isn't terrible. But I don't like that it leaked for you too. Wouldn't want it to break again in a year or twoo. Maybe I should try to remove it, like you did.

I guess this would require some sort of coupler that would "float" instead of being attached with the silver bracket. Are these things standardized? What am I looking for? I think it's a quick connect on one end, but not so sure about the other.

Thanks for figuring it out!! That was fast - this forum is pretty great.

Just take the part off and braze the crack, it probably won't do it again!

I ended up just deleting the bracket. and hard line.

Took it to the place I get hoses from and they gave me a fitting that simply took place of the hard line and bracket. Did not affect the Pioneer couplings just a straight piece that replaces the little / short hardline. I don't remember but probably a $5 piece.

Worked fine, cheap and easy. I think that hard line is just in an area the wiggles/stresses to much so a more flexible approach worked for me.

Put a piece of pipe split foam pipe insulation (the kind that goes over hot water lines) and zip tied in place. Foam was to prevent "scuffing" and vibration which I guessed caused my failure. After that Bob was my uncle.
