Adding Rear remotes

[J_J]

I would go ahead and draw out the hyd from the pump to the 3pt. Then if you need to interrupt a hyd line to add another valve, you will know where to cut the line or just re-route the supply. Keep in mind, that all valves should be in series.

Lately I have been finding better deals at Bailey's than at Surplus Center.
Directional Control Valves 220-907 Detailed Information
Hydraulic Cylinder Components, Products
If your Branson 3820I is rated at 8.4gpm, a 10gpm valve will give you better control than one rated for higher flow.

Just to add to JJ's good advice, the hydraulic supply loop likely goes from pump to loader valve to 3ph valve which is mounted directly to the hydraulic reservoir. The port on the loader valve that is connected to the 3ph valve is called a Power Beyond port. The loader valve should also have a low pressure return line going directly to the reservoir. The return port is typically labelled "out." Get a control valve set up for power beyond, route the flow from the loader power beyond port to the "in" port on the new valve, route flow from the power beyond port on the new valve to the 3ph valve, and tee the low pressure return flow from the new valve into the return flow from the loader valve. You can get low pressure hose for the return lines but high pressure hose is easier to find and cheaper in my experience.

If you order a valve from Surplus Center or Baileys, check out the current fittings in your system, do a sketch like JJ says, and note the fitting types and hose lengths. You can order fittings and hoses along with the valve. I personally like to use the stock hoses with nptf fittings and buy adapters as needed.

My Branson is a 3820 and the hydraulics are 6.9. I like JJ's idea better than the one I had. I need just the mount for the valve made and mounted on the ROPS. All the hydraulic lines will be shorter and it will be a cleaner application since it is nearer to the rear of the tractor. I am letting the dealer get me a price for the factory rear remotes bracket. I am going to go to a local hydraulics supply for my hoses and fittings, since I don' t seem to understand the different types. It will become clearer after I buy what I need for the job.

I have been reading all the many ways of adding these rear remotes to a tractor. I want to add one to operate a scrape blade to angle and tilt it. My dealer sells a kit for my tractor, a branson, for a single spool for $750, Ouch! In talking further with him he asked, " Do you use your FEL when using the blade?" i said not usually. He said a simple way to accomplish this would be to run more lines from the FEL joystick to the rear with QD's and just disconnect the FEL and connect the new hoses that will control the blade. Now the joystick will control the rear blade. Do you guys see a problem with this if I can live w/o the FEL when using the blade. If really needed I could reattach the FEL.

Thanks in advance for any ideas.

Here's the triple remote setup on my 2008 Mahindra 5525. Dealer installed when I bought the tractor new--$750 parts and labor.



Pressure comes from the power beyond port on the FEL control valve. IIRC you have to insert a sleeve in the PB port when using it for remotes.







The return from the remotes is teed into the low pressure line from the FEL valve.

Hope this helps.
Good luck

Nice job, Flusher. Have you found that mounting to the fender id stable enough?

No problem--Mahindra uses real steel in their tractors, not thin sheet metal or (gasp) plastic, so those hydraulic parts are tied down solidly.

 

[glukowicz]

Mine is fairly solid also. I think yours is the first one I have ever seen mounted on the fender.

It helps a lot to have that large flat top fender on my Mahindra so there's plenty of room for the hydraulic stuff.

Do you remember where you bought your valve from? And was the remote bracket made for you or did you buy it somewhere?

My dealer, Dave's Tractor in Red Bluff, CA, bought the parts and made all the sheet metal parts.

Dave is a TBN member and reguiarly posts here. His handle is "DavesTractor". You can send him a PM on this website or contact him on his website

The triple remote valve is made by Dinoil, a European company. Haven't been able to find a U.S. distributor yet.

Flusher , why would I need a sleeve on the PB port if I am using an open center?

 

[J_J]

You need a PB sleeve to separate the OUT port and PB port, so the flow will be directed out the PB sleeve for downstream operations, and the cyl expended fluid will only exit out the OUT port.

That is assuming that your valve has a PB port.

Open center means that the fluid is flowing at all times with the valves in neutral. When you operate a valve, you re-direct the fluid to a cyl or motor for power. All valves have to be in series.

 

[glukowicz]

So with the following valve that you suggested in a prior post below, would that valve need a sleeve before going to the TPH? Or would I just need the one in the FEL?

All hyd valves except the last valve need a PB outlet, and be installed in series. . The last valve is usually the 3pt valve. All valves OUT ports go to tank, and can tee together.

Yes, the valve above needs a PB sleeve. .

 

[glukowicz]

Is this because if you are not using the PB port, it would be blocked off and the out port would just be return to sump?

 

[J_J]

The OUT port of the FEL valve would go to the 3pt.

 

[glukowicz]

I think I am going to show my Polishness. I am very confused. Does the PB sleeve convert the out port from low pressure to high pressure?

My set up now is as I understand it: From pump to FEL to TPH to sump. If this is true, does the fluid flow into the FEL by the in port, the FEL valve has a PB prst that has a sleeve in it. So before the sleeve is inserted, the PB port is just capped off and the out port returns to sump. After you add the PB sleeve, the out port then goes to TPH and the out port on TPH goes to sump?

Is this right or can you see where my confusion is?

 

[J_J]

On some tractors, the only use for the hyd is for the 3pt. Pump, 3pt, tank.

The fluid goes from the pump to the FEL, and back to the 3pt. If you add more valves, the flow must pass through all valves in an open center system. Therefore a PB outlet is provided to pass on the fluid.

If you did not have a 3pt, the fluid from the FEL OUT port would go to tank.

The main reason for the PB is that a high pressure port is provided to withstand the high pressure when a valve downstream is activated. The cyl fluid is blocked from merging with the main hyd flow.

In a lot of valves, the OUT port can not take pressure above 500 psi.

Before you added the PB sleeve, the flow was from pump, to FEL, to 3pt, to tank.

After adding the 3pt sleeve, the flow is from pump , to FEL, to new valve, to 3pt, and to tank.

In a normal situation, with all valve levers in neutral, the fluid is flowing through all the valves with no pressure, just GPM's. If you push one of the levers on any valve and send fluid to a cyl, the hyd pressure starts to build when the cyl meets resistance, and will continue to build until the relief comes on and regulates the pressure. Any excess pressure is returned to tank.

If you activate the 3pt valve, the pressure is built up and reflected back through all the other valves.

On most valves, the fluid from the cyl the valve is controlling, flows through the OUT port and to tank.

That valve is spec'd "w/ power beyond" so you should not need to buy anything else.

 

[glukowicz]

So really when I add the new valve for he scrape blade between the valve for the FEL and the TPH, I will put take a hyd line from the PB port of FEL to the In port of the new valve. The put a sleeve in the new valves PB port and run a hyd hose to the TPH. The PB sleeve is already in the FEL valve since it was going to the TPH. Then put a tee at the tank where the line from out port of the FEL valve comes into the tank for the return. And then just put in hyd lines to the rear remote brackets with QC's.

Is this now correct?
