FEL Hydraulic Control 3rd Line connection??

[J_J]

I can tell you for a fact that if you use the QD's, and you fail to make a good connection, or a branch knocks the pump side QD off, the pump will probably fail.

BY remote are you referring to the 3ph, if so, it probably has a relief, but that is only for the 3ph. If you are not using the 3ph, the hyd fluid goes through the 3ph valve and back to tank.

What I am asking is, does your FEL valve have a relief for the work ports? If so, then your FEL circuit, and pump is protected.

If not, you might as well stop everything until you install a relief valve before the FEL circuit.

Before you installed the FEL, the pump output was routed to the 3ph valve which had a relief, and the system was protected.

OK I understand what you are saying now, yes! this would be a great concern, i had'nt thought of this possibility I'm sure could happen.

No I was talking about the FEL Remote Control valve, and the screw that was explain to me as being an adjustment for the " loaders" lifting ability,
I also thought I hear him tell me it was a "relief valve"
here is another picture, as a picture can explain better then i seem to be able to,
to the left of where I'm pointing is the inlet line from the pump,

Been doing a bit of Homework,
Google Image Result for http://i.ehow.com/images/GlobalPhoto/Articles/5009448/191083-main_Full.jpg

and should I be using one of these between the pump and the Qd's ?

I wished I had seen all the pictures earlier. But anyway, it does look like you have a relief valve in the circuit. Sometime soon, check all the pressures, pump, FEL relief valve,and 3ph relief valve.

If you are gong to use the QD's on the pump output, I would add some extra protection for the pump. The relief output requires another line that has to go back to tank.

A valve like the one you posted would work.

Since you allready have power beyond, why not install a rear remote for future use. I know hydraulic tilt is the bee's knees. Then you wouldnt have to worry about figuring out how to replumb the valve. The power beyond would just hook to an open center valve and the out on that valve would go back to the tank.

Definetly get a relief valve installed right after the pump.

Ken,

You will still need a hose for the tank port to return the fluid from the cylinders to reservoir. The PB sleeve will block the cylinder fluid from going out the PB port, so it has to exit the out port.

JJ You shaved
we all been talking about this power beyond "sleeve, adptor, port" and I really need to understand something? when I hear the term "Power beyond"
I think of using this as another sorce of power beyond what is needed as standard equip..... Ok! The way I have the return line hook up is from the PB coming out the side of the contol valve as you seen in one of the pictures,
Now if this is Not! where the return line should be connected then this might explain a lot of confussion I've had, now if the 3rd line I have been referring to and asking about removing from the system is in fact suppose to be connected to the "Power Beyond" this would mean that the return line should be connected to the T port at the top? which I have read one of you mentioning,............. Update: as for now I have connect the T port 3rd line to the reservoir by means of plumbing out the fill hole and adapting the rubber hose connection and hard line connection..

A FEL valve with a PB port, if connected correctly, will allow hyd fluid to pass through the FEL valve and routed to the back for remote valves, and the tank port is used to pass the cylinder fluid to the reservoir.

The PB port usually has a plug in it, and the fluid from the cylinders goes out the T port. If you want to use another valve down stream, you then remove the PB plug, and install a PB sleeve, which blocks off the fluid from the T port. the output from the PB sleeve, is passed on to the next valve. If the FEL valve is operated, it interrupts the fluid and sends it to the cylinders.

The third line really has no meaning, as the ports are labeled as to the function.

The valve as you showed in the first picture, was set up to pass fluid to another valve, through the PB port and sleeve.

If you are going to modifying things, you need to know the consequences. For instance, if the output from the PB port is routed to the back to a remote valve, and a QD is unplugged, and the relief on the remote is not working, then when you activate the rear remote, you are pressurizing the line from the pump, though the FEL valve, back to the remote valve, and if the line is dead-headed, any of several components could fail, pump, FEL valve, remote valve, or hyd hose. By now, you should be able to analyzes what happened to your pump.
