Allan, read your post and saw the pictures of the pump. Would this apply to most or all of the IH and Farmalls with the hydraulic pump bolted onto the side of the tractor (ie: Farmall 504). My 504 has to have the throttle gapped pretty good to make my loader raise, lowers fine. The other valve will roll the bucket both directions at fair idle. I have the hydraulic valves tore down on my bench right now, I did not try switching hoses first (dumb).
On one valve I found the un-latching piston frozen in place and the detent balls pitted. Also the detent balls spring is broken and the centering spring actuator is rusted and pitted. Searching CNH Parts right now.
I bought 2 used valves off Ebay for $230 shipped. I hope I can make two good ones and have a spare. I have enough o-rings for 4. I found a place that has the 376385R95 valve, remanufactured, $425 ea!
The same site also has a power beyond end cap for $250. To add dedicated loader remotes, without splicing into my supply and return, I have an idea. Since I have two end plates (one to modify) can I make a power beyond plate? The end plate has o-rings just like the valves. Can I mill/drill through the center of the o-ring groove and tap to accept ORB fittings and use this to power a loader valve or a 3-spool valve bank? Just a thought.
I can take pictures of the end plate if anyone has further help with this matter before I modify a perfectly good end plate (they are pricey, even used).

My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
