Adding rear remotes where there are none existing

Look at the "Foto Deutz #671303" again. Notice where the rubber line exits the housing
Without additional information, I bet that is a hydraulic pressure tap point. 'Might be for single acting cylinders (dump trailer etc) . I do not see any sort of control knob or handle for it however.
Or it could just be another return to tank for a system out of view ;-)

Dollars to donuts, you could cut into the smaller tube from the PS unit, the one that crosses behind the transmission cover. Rerout to a Power Beyond multi spool directional control valve (loader valve) and then return to that same pipe to restore the flow for the lift (I believe that line is the lift supply) One additional line would need to be added for return to tank (exhaust) from the new Directional (loader) valve> I'm making that claim based on the idea that the Power Steering valve is a priority valve, that passes it's Power Beyond function to the rear lift.

One way to tell is to try to lift a load while exercising the steering gear. If the lift slows or stops while the steering is in motion, that would demonstrate a priority valve in the PS unit.

Any Duetz dealers near you? Worth an ask...

A pump hanging off the rear pto might be fine for something like a back hoe or other major implement, but it would be a pain for a general purpose tractor, just to operate a front bucket. The added tankage is another thing...

What is the pressure developed by the Power Steering.

Should the question be "what pressure is supplied to the rear lift"?

The power steering may have an internal pressure reduction device ...or not ;-)

The Hurliman has much the same system as "might" be present on the Duetz.
Pump out to PS priority with pressure reduction
PB to rear lift
PS has a line to return to tank
The lift returns "internally"

You don't supply pressure. Pressure is developed in the hyd components.

The design of the pump determines the max pressure.

You need to know pump pressure to determine potential.

It may not be worth the effort if the pressure is low.

Would you build a FEL that would only lift 400 lbs or purchase the FEL for $1000?

The Power Steering probably does not put out much GPM, which determines speed, and the pressure, determines the force applied.

The hyd pump on my Power-Trac, has a max pressure of 3000 psi, so that potential might be developed in the hyd components in my hyd system.

Older tractors might work at around 1500 psi, so things have to be known or figured out or measured.

You contradict yourself, saying "you don't supply pressure", and then saying "you need to know pump pressure".
That's it exactly! "What pressure is available to the rear lift?".......... The pump supplies flow, and has an upper pressure limit.
I believe you are under qualifying the fitted hydraulic pump, thinking it is only a power steering pump. From the plumbing shown, the one pump provides fluid to both the steering unit and the rear lift. It should be able to supply other systems as well. Do you see something else?
Looking at the pictures snagged from the web of the same model tractor with loaders installed suggests there is capacity in the original equipment.
A call to a Duetz repair facility would have that number in short time. 1500 or 3K psi, there are cylinders that will do the work. ;-)

It would be helpful if the OP would post pictures of the pump, and the PS plumbing from the side not already shown.
I bet there is a good way to add an Aux circuit in a power beyond configuration.

Bottom line, Any additional hydraulic functions should be pulled from the lift circuit. If that is not the same pump as the PS, I'll be suprised. A quick look in the internet for a replacement hydraulic pump, returns a part that "looks" capable of supplying a loader. There are even some tandem units offered with dedicated power steering pump sections, but I did not confirm part numbers or application.

ps

Read the second post on this reference
Deutz D4006 misc. info requested - Yesterday's Tractors

seems that a power beyond feature is available....

If you take a hyd pump and put a hose in the IN port and a hose in the OUT port, and place the hoses in a bucket of hyd fluid, and then turn the pump, the pump will supply volume/GPM, and if you put a gage in that loop, you probably will not read any pressure.

In an open center hyd system like most tractors, with all valves in neutral, the pump is pumping fluid through all valves and to the tank with little or no pressure.

Pressure is developed when the hyd fluid meets a resistance, be it a cyl or hyd motor. Force is now being generated to do what hyd are designed for.

You do know that a small amount of hyd fluid can move a large mass.

You can check the pressure by providing max resistance to the pump flow.

I have no idea what the pressure is on that tractor, but someone can measure it and from that result, one can determine if a FEL is feasible.

Wow! These guys appear to "have it well in hand", here. Hopefully someone out there can help this man solve his problem.

I agree with this post,^^^^^^



I just checked Tractordata and the flow is about 6 to 7 gpm, after steering that doesn't leave much. A picture of the pump might help to see if a larger or two section pump could be added. If the OP is going to persevere with this then might as well get it right and see if he can have a second section that is large enough to handle the fel and other outlets if he is spending the money.

Help?

there's the pump! Right behind the exhaust pipe ;-)

Hi guys, sorry it took me a while to get back. Working 12 hour shifts suck. I've taken a couple of pictures of the pump. Also a picture of the hydraulic line where it splits to where I assume the fluid returns to the suction line from the steering. The splits is the big fitting you see in the line. The lines run together and one is behind the other which is why you can only see one line in the fitting in the picture.

I don't have a gauge to measure the hydraulic pressure. I had assumed that since there were other tractors my model out there I have seen pictures of with fel that mine has the capability. All advice and suggestions to me successfully getting rear remotes, of have a post driver I want to start using soon as well as add a top n tilt, and later on an fel are greatly appreciated.

I almost forgot, the brand and model number of the pump is Bosch 0510512302 in case this helps.
