Rear remote on a BX22.....

[JerryG]

That is the way that I thought that it was on the Kubota's, but I mis-read what Junkman said. /forums/images/graemlins/crazy.gif

Added Kubota rear hyd. kit to my Kubota L3010 last Jan. In the neutral (mid-pos) the fluid flows thru the valve back to the 3ph mounting. When the valve is operated to either the forward or rear position,the pressure is directed to either the left or right quick-dis at tractor rear.When my valve is operated to the forward position,the right sided Q/D is pres.I then plug in the supply (pres. to backhoe) to this Q/D.I then plug in the (return from backhoe) to the left side Q/D.To make all this work the valve handle is locked in the forward position.The backhoe control valve handles the flow thru,when lines are connected in this way.A word of caution,the tractor mounted valve must never be operated unless a hydraulic cylinder,or flow thru device (backhoe valve) etc. is connected to the rear remotes.

Does your valve have a return line? What would happen if someone "accidental" operated the valve with nothing connected to it? /forums/images/graemlins/confused.gif

The L series valves are not "external" so to speak. They are attached (stacked) directly to the transmission case and have no hoses for PB, inlet and return to tank. It's all done with internally machined passages. All you have is steel tubing going out to the quick disconnects and linkage for the levers.

Basically nothing will happen if the valve is actuated and nothing is connected. Same as an externally mounted spool valve. No oil will flow since it has nowhere to go. For an external valve, depending on the valve, the relief may activate and dump oil to tank.

Thanks for the explanation. You have confirmed what I already thought to be true. I just figured that after such a stern warning, that it would be advisable to learn what botaman2 was thinging of when he made the statement.... thanks again.. Junk.. /forums/images/graemlins/wink.gif

MadReferee's explanation was correct,the plumbing is as he stated. The warning I gave,was only to discourage valve use when nothing is connected to avoid possible damage to pump.When operated, the engine will slow down dramaticly as the bypass cuts in to relieve this pressure.

… The question is now officially resolved… Tonight…I 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… Junk..

Now that I have put the valve into the line that feeds the backhoe and know that it works, is there any thing that can be damaged by doing this? thanks....

No, as long as your valve has its own return to tank line which it should.

It seems to me that the challenges that BX22 and BX23 owners once faced when trying to add a rear hydraulic remote valve to their tractors have been considerably reduced with the advent of the BX24.

If you take a look at the hydraulic plumbing at the back of the BX24 (going from the tractor to the BT601 backhoe) you will no longer find only two connectors but three. There are as follows:
1) Outlet hose
2) Return pipe, and
3) Power Beyond pipe.

In other words, the owner can now mount a rear remote using only the plumbing connectors found at the rear of the BX24, without the need to run a long return hose towards the front of the tractor as was required on the earlier BX22 and BX23.
