Help identifying hydraulic ports

[ponyuk]

Hi,
I just mounted a hay bale grabber to my Massey Ferguson 1532. I'm trying to tap in to the hydraulics to add the grabbers hooks.
Can someone help me identify which of these is the hydraulic feed and which is the return.
My grabber control valve has an in and out, and I know it needs to be in series with my existing hydraulics.
Here is a pick with color coded ties on it

Hi Pony - Usually the return is the thickest hose - looking at your photos my guess would be the side hose (blue). However this is only a guess!

Do you have any more info - such as the make of the loader?

 

[ponyuk]

Hi,
Thanks for the reply.
My loader is the Massey Ferguson L100. All my hoses appear to be 3/8. As they are color coded, I can post a picture of where they connect to the engine if that helps?

That woyld definately help - although I am sure there will be sombody here at TBN who is familiar with the model and know the answer immediately ...

Red one:


Blue and yellow:


So I have the red labelled one towards the back, and the blue and yellow towards the front.

The red one is definately a return...

From the photo it appears that both the blue and yellow are seperate feeds (one per spool maybe?) - but I think you definately need the advice of someone who is better experienced than I am to be sure :laughing:

Keep your eye open for user JJ - he is great with Hydraulics...

Hopefully JJ will chime in, I think this is not going to work without some extra equipment.

The guy that sold me my new hay baler, cutter, rake, accumulator, and grappler appears to have some bad information. He thought the hydraulics were open center and I could tap in to the hydraulics on my remote. I set it all up just now and the grappler will only work when the lift is also operating.
I currently have a very expensive lead weight on my lifter and I suspect a large bill in the future to buy the extra bits I need).

I'm guessing I need a closed center valve, and to put this is parallel with one of my remotes? So, for example T in to the blue feed that control up and down and spur the feed to the in port of a closed center valve for the grappler. Then T the red return and spur that to the return of the grappler valve?

 

[ponyuk]

OK. I'm officially confused.
According to MF my 1532 is open center.
I'm obviously connecting this all up incorrectly and my open center valve supplied with the grappler should work.

Standing by for an expert :confused2:

I take it you added a "T" in the pressure feed line??......That won't work, the flow will take the path of least resistance and flow through the valve you are not using.....that's why the grappler will only work with the lift is operating.....this has to be in series to work on an open-center system

Do you have pix of your new valve

With the original question, the feed line on your FEL valve is on the same side as the pressure relief valve...(not shown in pix cuz of plastic cover).....

 

[ponyuk]

Hi I didn't add a T, I had them in series.
I had the hose marked blue going in to the "In" port on my new valve, a hose from the "Out" port of the new valve going to where the blue hose was originally.

My new valve is open centered. So with the new valve attached I can operate the original controls just fine. It appears the original controls are not open centered as operating the new valve does nothing unless I also operate the original control at the same time. It appears the original control only allows flow when it is operated.

I'm 'thinking' blue and yellow supply the controls and red is the return. I thought blue and yellow would both flow continuously, and be diverted by the original controls. In which case I could tap in to either to operate my grappler. In fact what I am seeing, or think I am seeing, is blue and yellow have no flow until you move the original control level.

This is the valve:

I found this thread:

I dont think I can tap in to my original controls...

If you pull the cover off your old valve, I think you will find that the ports are identified by castings cast right into the body. I think yellow will be "in" and red will be "out" or "tank" and blue will be "power beyond". The "power beyond" is the only thing that will be changed on the old valve. It needs to go to the "in" on the new valve. And then the "power beyond" of the new valve needs to go to where the "power beyond" of the old valve used to go. And the "out" on the new valve can be T'd in with the "out" on the old valve.

The link you supplied for your new valve does not appear to have "power beyond" capabilities. And you will need a valve that does.

[ponyuk]

Thank you DRL.
Can you recommend a valve I should get to make this work.

 

[DRL]

Surplus Center has many that would work, like this one if it has the flow you need.
Surplus Center - 1 SPOOL 8 GPM PRINCE MB11B5C1 DA VALVE

or this one (power beyond sleeve sold seperately)
Surplus Center - 1 SPOOL 14 GPM PRINCE WVS11B5C1 DA VALVE


Do a search for "power beyond", it has been explained lots of times on this forum.

Thats perfect. thanks.

ponyuk,

If the valve you installed is an open center valve with PB, then it should work.

Your FEL valve, with PB, will have 7 hoses if it is operational, to connect additional valves.

If you the connect the new valve ports correctly, they should work.

 

[ponyuk]

Thanks JJ. It looks like the new valve I have is Open Center, but is not Power Beyond.
I ordered a Power Beyond compatible valve. Hopefully this will be all I need to do.

I need to read up on PB. I cant get my head around why I need a special valve. I imagined hydraulic oil was flowing through my FEL valve at all times, and was simply diverted when I moved the lever. Logic says tapping in to that flow would allow me to divert the flow to my new valve, and have it take its normal path when not in use (as my new valve is open center). I'll read up on PB and see why my understanding is flawed :confused2:

 

[ponyuk]

One other question. As the grappler will not be in use all the time, I'd like to be able to remove it. Would this be a case of using a couple of quick connects and simply unplugging it, I dont need to connect the two disconnected ends together?

 

[DRL]

Are you talking about leaving the valve on the tractor and disconnecting the lines to the cylinder? If you are talking about the lines going to cylinder, no, but if you activate the valve with them removed you will deadhead the pump. Better to put them together to protect pump and keep the QC's clean.
