Ford 4630 Hydraulic Questions:

[straightsix240]

I haven't replaced any o-rings, yet, but the previous owner did and I don't know if he just went to NAPA or actually ordered the replacements...

My power beyond block, I think, only has two ports, but I need to go check. That's a good point about the bolts, I'll have to check on that.

Thanks ETpilot! What you're saying sounds suspiciously like what might be my problem. I need to check on the valve when I go to the barn to feed the cows this afternoon, then I'll check back here. I think it's a two port.

I had a bale of hay on the back of the Ford on a set of 3PH pallet forks as ballast when I was moving the wood chips. I didn't need the ballast it was just already on the tractor. So this 2 port/3 port difference and a problem with pressure related to the 3PH sounds like it just might be what's wrong.

Thanks a whole lot for taking the time to respond! I'll update later...

Ok, I checked the power beyond block, (if that is the correct term for the aluminum block below the valve with the operating lever) and it only has two ports. There is one small allen screw on one side of the block as well.

Where is a good place to get a three port block, if that's what I need? Then, where would that third port go? Do these blocks come with instructions, I guess?

I got some pictures that I'll try to get posted soon; I'm not very handy with a camera and computer...

Thanks!

Posting a picture may help. I have attached a picture of my installation. Originally my valve, in the picture, sat on top of the accessory plate. Installing the hydraulic manifold required removing the valve, installing the manifold then reinstalling the valve on top of the manifold. The manifold has 2 ports that I use to feed the FEL valve which is a power beyond valve. The 2 hoses you see in the picture go to the FEL valve. When the FEL is removed, I have a short hose that I use to connect these 2 hoses to keep the fluid flowing. Hope this helps.

What you refer to as the power beyond block is actually your hydraulic manifold. Or the adapter as pictured in your second link in your post #3. It should have 2 ports. According to my installation, the valve that connnect to these 2 ports should be a power beyond valve, which has the 3 ports; pressure, return, and PB. If the valve is not being used, then the 2 ports have to be joined to keep the fluid flowing.

My use of the terms 2 port and 3 port may have been confusing. Post or PM me your email and I will send you my installation instructions. You can use it as a reference but you really need to review the installation instructions for your particular model manifold.

Remember, the loader valve needs to be power beyond capable to begin with, meaning it has to have three ports connected to the tractor. The number of ports in the aluminum block is not critical as long as the sump return from the loader valve has a free passage to hydraulic reservoir. You can fabricate a return port into the fill port on the back of the rear main housing if you have to, or some other existing place on the tractor, although there are few such options on most 30 series tractors.

This is the remote valve that is leaking. There are two hoses coming into the aluminum block (the manifold). Then there are two hoses leaving the valve to the two remote connections above the 3PH.



This is the other side of the remote valve; here you can see the two hoses leaving the actual valve to the remote connections above the 3PH.



This is the FEL valve for reference. There is a hydraulic hose that enters the rear end of the tractor, you can see it in the first picture I posted in this message. I think this comes from the FEL valve, but I'm going to go out and double check that now.

Thanks for the help guys!

Ok here's the plumbing diagram after scraping some grease off to figure out which hoses go where. Part of my confusion is that I assumed the plumbing started at the FEL valve, then went to this manifold/remote valve... Obviously not, everything starts with this manifold, then the remote valve, then the FEL valve.


Starting at the manifold (1st picture in my last reply):

Two hoses leave the manifold. Looking at the picture above: the hose on the left, (which is the right side of the tractor from a driver's point of view), goes to the BYD plug on the FEL valve.

The second hose on the manifold goes to the IN plug on the FEL valve.


The two hose coming out of the remote valve go to the two remote connections above the 3PH.


Then from the FEL valve there are seven hoses:

Four go to the FEL.

The IN and BYD come from the manifold.

The OUT goes to the sump return.


Is this correctly plumbed? Not sure from your diagram ETpilot...


Gonna try to call a dealer and see if I can find out some info, at least find an o-ring kit for the manifold cause I think I need that regardless if this is plumbed right.

Thanks!

One more note: the second hose on the manifold, as I referred to it above, (that goes to the IN plug on the FEL valve), is marked P on the manifold.

It all sounds correct to me, providing the two hoses between the aluminum block and the in and byd ports of the loader valve are correct. The flow from the block should go to the in port of the loader valve. If that's the case, your plumbing should be right, and the leak comes back to the fit of the orings under the remote valve.
