Hope this got your attention 2255tr. I got the seal, thank you, but it only looked like half of my original seal. I put it on, connected the hose and I have a slow to moderate drip where the tube comes out of the middle of the nut. As viewed from the side in my picture, the original seal looked like the letter "T" with a wider section at one end while the one you told me to get is the same diameter throughout. Any ideas??? Also, the threads on that nut weren't looking to good, do you have any idea about how to get a new end? The hydraulic places I have been to don't recognize it, and the route I WAS going before you helped me was to thread their standard fitting in there. But the closest we could find had the thread pitch off just enough it was going to be a one time deal as it would probably strip the threads a little and also drip slowly.

Thanks for your help so far!!

The Ford 8000-9000 series also uses a similar seal. On our olivers, we usually get the nut and seal kit from our Oliver dealer. One thought regarding a slow leak is that there is not enough compression of the seal. The compression nut usually bottoms out without sufficient expansion of the seal. I have used one or steel rings to increase compression. Also, was there another ring in the valve body. Sometimes this type of seal will have two still rings, one on each side of the seal. As stated, an extra ring has usually fixed my leak problem. Hope this helps.

I first will apologize if that seal did not completely repair the leak. It has worked for me in the past.It was the cheapest route that I know.
Later 55 series and the early whites did have that hose as flared ends (#30-3143945) and they had a thread in adapter to the pressure valve.

Adapter(50A173) dimensions 7/8-14 x 1 1/16-12 and uses 15/16 I.D. o-ring (197885A)to seal the adapter to the valve.These are all old part numbers from the 80's. I will not guarantee they are still any good. This is a much higher repair route and is what you were originally going ot try and do.

No apology needed! I should have stated I am thrilled to have found that seal so I could get this back together as I was having to move bales by rolling them and messing them up, big headache. Just happy to have the tractor running again, but wanted to try and figure out how to get it a little better.

Thank you and IanC for the info!

I went back and read your original post to be sure. The sealing nut your are needing was sold as an assembly only. If you look at the thin "washer" to the right of the "T" shaped piece when you tighten the nut into the fitting this washer bites into the tube to keep it from coming out under pressure. Get the new sealing nut assembly from AGCO, push the new nut onto the tube then cut a little off the end of the tube to give the new washer a new place to "bite" start the nut into the fitting then push the hose in till it bottms then tighten the nut. Had to really dredge the memory banks to remember. The same sort of set up is used in most of the 3000-5000 series Ford tractors for the pressure line for the engine mounted hydraulic pump.
