Have a persistant hydraulic leak at a tee fitting down by a drain plug for i think is tranny. The T has male thread going into a round housing held in with s snap ring, a short hose from another round housing rainbows up over a center round housing into 1 side of female part of T, the other female side has a steel line going back to valve stack, as well as a steel line from middle round housing I am 95% sure this related to pto brake valve if I read part diagram correctly. I am needing the T - #70914762 in Agco parts book but hoping someone can verify my part. Tried getting the T at our local hydraulic repair shop but no dice. Tractor does have hydraulic pto engagement. Thanks.

I was surprised the AGCO parts book has a hose between the Brake pistons. My 190XT has a steel tube, The tee has an 1/4 npt thread on the side and 3/8 inverted flare connections on the run. I looked at another housing I had, but the tee was broken off and the tube/hose was missing.
I would double check to see what was actually used on your tractor.

Joe, the hose is what is on our tractor, I just removed the TEE this afternoon and discovered the male stem was almost broke in 2 and I accidently finished it off. You guys seem to be "IN THE KNOW" about parts,could either of you tell me if this part is still available anywhere in the USA ?

An Agco dealer should be able to give you price and availability. Plus they should be able to check other dealers inventory to see if anyone has it in stock. (Not likely). And welcome to the forum.
