Help me with this hydraulic fitting..

Rtkman706 · Dec 18, 2009

Here is a picture of the hydraulic coupler that came off my 706 (original fitting?). Also pictured is the hose end which also happens to be the oring type.
What is the easiest way to replace this old connection? I tried the local hydraulic place but it would take 3" of adapters to get it to work. I may have to get a new hose so I'm not too concerned about the hose connector.

Take that disconnect to your local hydraulic shop. They should be able to make a new hose with swivel flared 37 degree JIC nuts and supply
the JIC tube fitting with the correct male tube threads and the correct male threads for installing your new hose. If it has a lot of pressure I would use double braided hose. Here's a hose with JIC fittings that I made with reusable ends. Hal

you can just buy the oring and install it we did it last summer onson,s 706 we bought our o ring at farm store

I think the red coupler has an adapter in it. Remove the adapter and a hose should screw into the fitting.

Okay, what are you trying to "replace?"

The entire coupler? They make standard Pioneer-type couplers with O-ring fittings. Your local hydraulic place isn't much of a hydraulic place if they can't make it work without a bunch of adapters.

I think you are correct. It is worth trying anyhow.

that hose end looks wrong to me, that dose not look like a pioneer fitting, are you sure it is?

see if this works..

Yes it's the wrong hose end (came attached to a loader from a different tractor).
I think I will have to replace both the female and male ends but getting from the tractor (Oring female) to a female coupler to a male coupler to a Oring hose end is the problem.
I tried removing the adapter attached to the female coupler but it's going to take some more torque. I thought it might be one piece. Will try to get it out today.

Yeah the entire coupler needs replacement. Your right on the hydraulics place.

The hydraulic block on the tractor requires a 7/8"-14 "90 Duro" O-ring fitting.
The standard female coupler from the factory is pictured. If it have international stamped on the collar, it is a safeway adapter. This will accept safeway and pioneer style male couplers.
If you were able to remove the adapter from the female coupler, it is just a 7/8"-14 x 7/8"-14, 90-Duro O-Ring adapter.
I'm still unclear what you're trying to replace or why, so I'll cover both. You can get both the 90 Duro O-ring and the internal 70 duro O-ring inside the female coupler if either of those leak. If you need a new Female coupler CNH 374780R92 is the only one I've been able to find. You will need to use the 7/8"-14 x 7/8"-14, 90-Duro O-Ring adapter as the coupler is female thread. If you can't find the factory replacement, you can use a straight adapter 7/8 O-ring to pipe. These are expensive puppies, so I just replace them with OEM.

If you can't get them to mate, A NPT standard pipe (what ever your loader hose requires) to safeway/pioneer coupler will work, as pictured above.

Thanks for the good info.
I was making it too hard:
I was trying to reuse the old female coupler (international stamped on collar). So I just got a couple of pioneer male hose fittings (8010-4). That worked on one hose, but the other hose is an Oring end. I think there was a male end that pioneer makes which will convert the Oring to std male tip. We'll see. I'm sure I'll be taking a shower in Hytran before this is all done.

I was told a hy-Tran shower is part of making oneself a man!

Help me with this hydraulic fitting..
