MF 204 loader needs hydraulic hose repair

[a.bourbon@comcast.net]

1963 MF 204 with bucket loader has blown hydraulic hose. No one in my area has the fitting to repair it. The connector is a 90 degree 1/2 inch tube with an o ring. Anyone know where to get this fitting?
On a complete hose?

I think what you have is a 7/8x14 ORB fitting which is a straight fitting that seals with the o-ring instead of a tapered pipe thread. A
fitting should be readily available at any hydraulic shop. you can also buy an adapter to go from 7/8 ORB TO 1/2 NPT ON FLEA BAY.

Here is some pictures of what the fitting looks like. Anyone know where I can get this or what it is called?

Here is a picture of a fitting that maybe could work in place of the other one. It looks like a pipe thread with a 90 degree connection. Anyone know what this is called?

The 90 degree adapters between your hose and the valve body are 90 degree NPT adapters, male NPT pipe with a female NPT swivel. The hose end appears to be male NPT. You would need to determine the actual size. They look like they might be 3/8" or 1/2" NPT.

Where does this hose go? The end in your first photo looks like one I would expect to see on power steering, or a transmission cooling line. Is that an actual O-ring (does not look like it to me)? It looks like the tube was formed to make that shape for sealing. If that is the case you may need to go to MF for it or find a hydraulic shop that can put that end on a hose fitting. Just my thoughts.

The photo that shows the 90 degree bent tubing has an o ring that fits over the short end and butts up against the rounded flair piece.

Where does this hose go? The 90 degree O-ring end attaches to what/where? And the other end goes to what/where? The hose may be in the parts book but knowing which one and where it is are required to look for it. Photos of where it came from?
 

[a.bourbon@comcast.net]

The end of the hose with the 90 degree tube with the o ring goes to the loader control unit like the second picture but with this connector. The other end goes to a steel tube running along the lift arms to the cylinders. I have parts book for the tractor but it does not show any parts for the loader attachment or hoses.
 

[Jim.ME]

The loader should have a tag on it with the loader model number and serial number. It will have a separate parts catalog.
 

[Jim.ME]

If that is the type fitting on both ends of the hose the adapters will not work, you need those ends.

If the loader is a Massey Ferguson the model 99 and model 102 were common on those I believe.
 

[Jim.ME]

An early 99 has a hose, going between the valve and bucket cylinder steel tubes on the loader frame, that looks like it might be similar to what you have. Part number 705109M91. You would need to check it out with a Massey Ferguson/AGCO dealer as far as what it has for ends, diameter and length.

Thanks Jim.ME
I Found online a MF 200 loader parts list and retrieved a part number (705 441 M91) for the hydraulic hose I need. Called a MF dealer near me and they are looking to see if there are any in stock. If that does not work out I think I will take a swivel female connector and braze it to the tube section that goes into the control
unit.

 

[Jim.ME]

I would braze a straight hydraulic pipe coupling to the old end, then you can have a hose with a pipe fitting end on it to screw into the side of the coupling you didn't braze to. What ever you use get real steel hydraulic components. I hate to see hardware store fittings on the pressure side of hydraulic systems. Most are only rated for 150 psi working pressure. They are an accident waiting to happen at 1000 psi plus. Yes some hold, but I have seen some split as well.

Some hydraulic shops have hose fitting stems that ends like yours can be brazed/welded to, then are assembled by attaching to the hose with a crimp ferrule. Below is a sample from a Gates catalog in the Power Crimp section. Different suppliers may have similar depending on the hose brand/system used.

hose. Thompk
