3-Point Hitch No Hydraulics at 3 PT or Remotes

[jbain]

This is what the FEL valve instructions read:

PB would be used if a valve is to be added downstream.

I have no valve downstream. Still can't figure out why it was hooked up on the old valve?

The PB plug varies from valve to valve though. The old one might not work on the new valve.

The valves downstream are the remotes and 3 pt. So you'll definitely need PB. If you power the downstream valves using the tank line from the loader valve, you risk blowing the seals on the new valve. Worst case scenario you can blow the pump also, as the relief valve have the exhaust side under pressure and can't relieve the pressure to the tank. So it's basically dead heading the pump.

Please take a couple of pictures so we can help and advise you better.

If you did not have a loader then the flow would go directly to your remote valve then to your 3pt hitch. To add a loader valve, flow goes to loader valve then to remote valve and on to 3pt hitch.

I sent you a PM with my number. Feel free to call and I will explain it better.

Attached is a diagram of the hydraulic block where the FEL connects. The PB was connected to A line where the ? is.

That would be what I would think. You have to install the PB plug(adapter) in the new loader valve and connect it the same way the old valve was connected. This will allow your remotes and 3pt work without damaging your new valve or your pump. Any other configuration will result in very costly failures.

When you finish you should have a line feeding the valve, a line going to return, and a line to the PB port on the diverter block.

Now we're getting somewhere. I didn't realize that Kioti uses a slightly different hydraulic block than most brands, although it's easier to change when needed.

I attached a picture of the diagram and I added the connections there.



However you have to change the slit to the D position, so the flow will go through the loader valve, then out from the PB port to feed the remotes and 3 pt.

Thanks guys will give it a try.

Well, this is a very confusing thing to deal with. I being told if I don't use the PB I will damage my hydraulic system. How does the PB/FEL valve control pressure over the pressure control valve in the hydraulic block? I have attached the hydraulic block diagram again. The item in the bottom diagram between the input B and the return is the pressure regulating valve for the entire hydraulic system regardless if there is a FEL or not. The FEL has a pressure relief valve too that protects it form over pressure. See attached.

I checked the setup and the spool valve in the top diagram is in the vertical position as stated in the instructions for installing a FEL. I don't have the PB hose hooked up and the port in the hydraulic block is plugged. The instructions never mentions the PB connection.

There must be a error in the manual about the position of the spool valve and or the lack of a PB connection.

Currently the remotes and FEL works with the system setup as described above. The system pressure control valve should maintain the pressure and the FEL pressure relief works.

I am sorry you find it confusing. It really is not that bad. In the Prince PDF you posted it clearly tells you to use PB to power anything after the loader valve. The hydraulic block is a diverter valve that diverts flow from the remotes and 3pt to the loader valve. Therefore, the remote and 3pt become downstream valves requiring you use PB.

If you insist on not using PB and feeding the remote and 3pt with the tank line and PB plugged, please update this thread when the valve fails. It would be interesting to see how long it takes before seeing a failure.

Please answer this:

Why are you calling the pressure line the "tank line"? I would think the tank line would be the return line.

What valve is going to fail?

Where does the hydraulic pressure come from when there is no FEL?

Thanks,
