Another Rear Hydro Question

[gsdavis1]

OK, I have a strange tractor. It is made by the Goldoni corp (Italian) and it has a chinese diesel engine. With that being said it is very hard to get parts for it.

I want to add rear hydro ports on it. I am unsure how to go about it. The 3 point lift is fairly simple and I have had it apart twice so I can clearly see the high pressure in line from the pump and also the low pressure return line.

I want to also add an extra external tank for more hydro fluid in the layout.

I would also like the 3 point to be operational while the power beyond is in use (I wont use them exactly at the same time but would rather not have to "switch" back and forth as I need them.

Any one out there have a drawing or something of what I would need. I have a hydro tank and even 2 control valves that I could use. Also lots of disconnects and extra lines (all given to me )

I remember seeing somtime in the past where someone "broke" into his hydrauics and added rear ports but he had to attach a hose between them when not in use to complete the circuit.

Thanks for your help guys.

I'd break into the high pressure "in" line from the pump, take the flow through the control valves (open centre I presume) and then return the flow to the linkage.
You won't have to switch between the two, both will be available except the linkage when the control valves are being actuated.

You lost me. I do have a control valve that is open center (i believe) but where would I put the tank? Also, what do you mean "return the flow to the linkage"? I would like the rear ports to be able to be used for a log splitter. If I set it up like you suggest, wouldn't I only have pressure to teh back when I am holding the valve open?

Get a valve with PB... instal the valve after the pump.. use an OC valve.. that way flow to the 3p isn't effected except when oil is diverted... and then you have the availability of using a remote.. etc.

Are you really gonna need the extra oil / capacity? if so add a big inline oil cooler.. or an inline filter.. get one of the big 1-g filters.... though my rec is the cooler..e tc.... easier to plumb than a tank.. and has a dual purpose.. dont forget all your extra lines will be holding fluid ( and disipating heat )..

You need a hydraulic valve to operate the rear remotes you wish to install. Make sure the valve you get has a pressure inlet, a outlet to your tank and a power beyond port. Plumb the pressure line from your pump to the inlet, T the outlet to tank into the return line from your 3PH valve, and plumb the 3PH valve inlet into the power beyond port on the new hyd. valve. Then plumb your working ports, on your valve, to the rear with q/couplers on the ends.
I think the large filter idea is a good one, just install it on the suction side of your pump along with your original filter. Be sure so seal all your joints well, so you don't suck air in the suction line. I hope this is understandable. Good luck.

As the other poster said.. Power Beyond.

If it was me and all I was going to do was use a 3ph spliter I would just split the high preasure line to quick connects and use a short hose to connect these when the spliter was not in use. I would want the valve for the spliter instaled close at hand, not up on tractor.

Sorry for the late reply, you've probably finished by now!
Don't think you'll need an extra tank.
To "return the flow to the linkage" I mean, cut through the current line to the linkage, take the flow from the pump to the control valve.
Where the oil comes out the other side of the control valve (as it does when the levers aren't being activated) send that oil to the other side of the line you originally cut, where it will go on to the linkage as per normal.
