Loader controls

[Mustanger05]

I am trying to locate a possible replacement for this controller, its on my MF65 and it is for my front loader. Any ideas or suggestions would be greatly appreciated, thank you.

When you do, you might consider replacing the water pipe fittings with real hyd fittings. While that tractor probably doesnt make a lot of hyd pressure, its never a good idea to use galvanized water pipe fittings for hyd. Water pipe isnt designed for the pressures of a hyd system.

Something like this should do and get you to a more modern single lever control. You will need port adapters from the SAE ports to your probably NPT connections. Surpluscenter will also have the Ts and whatnot to replace the noted pipe fittings. You will need to adjust the relief valve down to whatever the tractor runs at.

As far as an exact match, you're going to be out of luck. That valve was custom made for that loader, and returns the oil back into the frame of the loader via the 4-bolt plate. That model loader has been out of production for at least 50 years, I'd imagine.

What I've seen done is, a custom cover plate for the hole is made with a bung hole to accept the return line from a generic 2-spool open center hydraulic control valve. A mount will need to be fabricated for the valve, which you could also incorporate into the 4-bolt cover plate.

Could be more or less T into that breather port to return the oil? I imagine one has to be careful dumping oil in the
same pipe air wants to get out, but something like that might be easier to fabricate, just a different option?

Also you might find some info at a good Agco dealer, as Davis loaders were absorbed into the Agco company. I do struggle with the Agco on line parts so this is as far as I got.

BarnyardEngineering has the best answer on returning the oil from the valve to the reservoir and mounting a new valve. I would not use the breather hole for a return. I would want to keep the breather working, and not risk returning oil coming out the breather, if tee'd into the same hole as the breather.

I'm having the same issue with AGCO as far as parts go. I have a M-40 with a M-34 loader and the spooler valve for the dump has gone bad. Not one to be found. I'm going to have to make a plate with inlet hole and getting a double end threaded pipe to dump the oil back into the frame rail. Would be using just 2 bolts to tie the assembly down. Everybody's right please don't use pipe fitting, they don't work.

There is actually nothing wrong with using pipe fittings for hydraulics.

You have to know your system. Return lines are low pressure.........requiring fairly common pipe, and fittings.

It is very common to use pipe fittings for high pressure lines. They're available in 2000/3000psi variants. Very common around here, being as it's oil country.......but should be available from any good hydraulics supplier in most areas.

Whoops, we couldn't find that.

Don't confuse forged with cast. Cast fittings are low pressure.

FWIW..................my loader is plumbed with forged pipe fittings...........WELDED TO THE MANIFOLD PLATE (Horrors!!!!!).

The breather line on OP's reservoir is simply an air inlet/outlet. Not high pressure......perfectly fine for standard black pipe.

A lot of hydraulic fittings are made with 12L14 due it's machinability. It's a medium strength material that you'd not associate with high pressure fittings.........but it's quite common.

Note the mixture of nipple types on this valve block I set up. There are 2 high pressure pipe nipples, and one regular black pipe nipple for the return line.

High pressure forged pipe elbows. Believe me guys, this stuff works, and is an accepted standard.

While I'm at it.

When you look at a part, and are trying to figure out whether it's cast, or forged. Look at the parting line. Generally cast parts have a small parting line, while forged parts have a bigger parting line. This isn't totally dispositive, so treat suspect parts with some degree of suspicion.

You should be clear on what you have. From your past posts it appears you have a MF 40 industrial tractor with a MF 34 loader. I suggest this as back in the transition time around Ferguson, Massey Harris and Massey Ferguson there was a 40 Ag tractor.

The common replacement for the valves like yours, has been posted. A cover plate with a port for the return hose from the new valve is made and installed over the opening where the current valve is mounted. A new mount has to be built for the new valve you chose and new hoses may be needed to tie the valve into the existing tubes on the loader. The main relief valve of the new control valve will need to be adjusted to your loader's specification.

In the future I suggest you start your own thread. This thread is only a couple years old, but replies will be given to things in the original thread, not your current post, as people tend to read part of the posts in a thread and miss one added on like yours.

I will recommend getting hydraulic fittings from the hydraulic shop you chose to use. For the few fittings you will need there is not much sense in trying to determine the right general pipe fittings, as well as the fact that you might need O-ring boss or JIC fittings to match the new valve or hoses you chose. farmersamm is right there are high pressure fittings and pipe you can use, but you need to know what to get, if you buy hydraulic fittings, you eliminate some of the checking and shopping.

We did replace our loader control valves on the 175 Massey with a complete set of aftermarket set of spools from force America. It cost some money but worked and then the parts searching is over. I’m sure others would work as well pick somewhere local if you can that will supply you parts. It’s possible they will sell you the same thing on this very website if you know where to look

This is what I ended up doing.

I dont wish to argue or disagree with you on a very nice message.

Most, I say most, folks go to the hardware fleet plumbing section and get the cheap galvanized made some other country water pipe fittings. They do screw on to the hyd pipe fittings just fine. But they are usually set up for 600# pressures, and have pretty poor threads cut onto them these days.

Don’t use those.

You have some different pipe fittings, which most of us have never seen at the corner hardware store. I’m sure those are fine, as you describe.

I just hope we aren’t confusing people that ‘oh pipe fittings are just fine…..’


In fact I just did the very thing this spring. My planter marker arm plumbing sprung a leak Saturday afternoon. The special hyd line was at a dealer 50 miles away but wouldn’t be open until Monday morning. So I went to the farm store and put together an 8 foot hyd line and about 7 fittings to adapt from a JIC small fitting to a 1/8 inch fitting on the other end. 2 common plumbing pipe bits were used. It all was safely away from me or any other person if it blew, and was replaced with the proper stuff in a couple days. But I’m aware pipe fittings from the hardware store are not rated for tractor hyd pressures.

Ya know................................I might have made a mistake. Unless you know your supplier, or your supplier knows your needs...........it's probably not a good idea to used high pressure "standard" pipe fittings. I daresay most folks don't even know the psi on their systems, so there are safety concerns. Dedicated, purpose made, hyd fittings are a safer bet. Takes the guesswork out.

Thanks for reaching out! For the MF65 and its front loader controller, I’d recommend checking with a Massey Ferguson dealer first—they often have access to original or compatible parts. If that’s not an option, you might also want to look into aftermarket hydraulic control valves from brands like Prince or Cross. Just be sure to match the flow rate and pressure specs. If you can share a photo or part number, I might be able to help narrow it down even more. Hope that helps!
