Rear remote on a BX22.....

[JerryG]

The last valve in the series doen't have to have power beyond, but all the rest does. That is the reason the backhoe has only two lines.

Jerry... what happens if you tap into these two lines and add a return line through the rear remote valve? Will the backhoe still work or will I have "stolen" all the fluid and put it back into the reservoir???? /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

Most backhoe setups must be the last valve in line since they have no power beyond. Also, most backhoe setups are plumbed so that the 3pt and any valve after the loader is disabled (or must be disabled manually) thus effectively making the backhoe the last valve in the circuit.

I have seen the plumbing for backhoes done many different ways, some right, some wrong. One thing that you do not want to do is have the return to tank line dumping into the high pressure power beyond line when there are working valves down stream. The most common way to plumb that I have seen on Kubotas (and it's not correct by the way) is to take the loader's PB line and run it to the rear for the backhoe and the other backhoe line goes to the loader hydraulic block to continue the circuit. This plumbing method requires that the 3pt be disabled manually which means the rest of the circuit is then really the return to tank circuit.

Now I have seen a remote valve connected to the backhoe QD plumbing as above (and adding a seperate return to tank line) and then running the backhoe from the valve's work ports by keeping the lever in an open position. It generates some heat in the remote valve but it does work.

I have not looked at the BX plumbing so I cannot give you a definitive answer. However, if you tell me where the 2 lines that connect to the backhoe eventually terminate I could give you a good answer.

I will try to post a schematic of what you need to do this evening. I think I have one with a loader valve, two different control valves and a two line backhoe all in series.

I will have to try to trace them to see where they come from and where they go. It is so tight in there, that it might not be possible to figure out there origins. I looked last night, but it wasn't evident and I figured that I would explore more in daylight. Thanks.. Junk...

One of the backhoe lines is a Siamese with the line that runs up front, so I assume that it the pressure feed line. The other line goes back into the transmission, so I assume that is a return line. These are usually hooked up to the backhoe valve and when the backhoe is removed, you couple them together.... thanks....

<font color="blue"> For those that might want to add rear remotes, the fitting is a 9/18-18 JIC adapter and the hose is approximately 38" long.

Junkman,

Just for the sake of accuracy...should that be 9/16-18? I think so but am not absolutely sure... /forums/images/graemlins/confused.gif

You are correct..... poor eyesight proof reading when I am tires.... ah.... tired..... Junk.... /forums/images/graemlins/grin.gif

The question is now officially resolved. Tonight I decided that I didn't want to drill holes in my floor pan to secure the hoses if it wasn't absolutely necessary, so I pulled the hoses out from under the tractor. I then rerouted them to the back of the tractor temporally and hooked them to the backhoe line. I tried the backhoe outriggers and they lifted the rear of the tractor as usual. I have to assume now that this will work. On Tuesday, I am off to the local hydraulic supplier to purchase two new hoses of the proper length for this "modification" to the BX kit that I purchased. If you have anything other than the BX22/23 tractor, you will still need to run the hoses to the front of the tractor if you want rear remotes. I will post pictures when this is complete..... Junk..

Junkman,
Here is the picture that I told you, I would post.
