Farmall 504 Hydraulic Remote Valves...

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).

Thanks,
Charles

by the way, i think your valves have a built in float position. you need to hook up your hoses correct so that if you enter the float position, the loader is headed "down" already. the levers pushed forward, while sitting in the seat normally should be the down and float positions and raised will be pulled back. the float can be locked out too if you have all the parts, but it's still not 100% accurate. that's another reason people like to add dedicated loader spools.
