New Holland TN65 trying to add a third function valve....

[JPuck]

I'm trying to sort out my existing hydraulics to add a third function, but I'm in over my head when it comes to equipment hydraulics.

I've got a Woods 1020 loader on a New Holland Tn65, the loader valve has 7 hoses on it, four go out the loader arms, of course, to the loader hydraulics.

The other three go back to the rear remotes, but I can't sort out which one is my Power Beyond from the loader as it's not marked on the loader valve.

Any help is appreciated, thanks.

Are there any letters on the actual valve body?
My first guess would be that the lowest line on the rear end is the return to tank (reservoir),
as far as which is power out and which is the power beyond of the other two no idea.
If you quickly operate one of the loader valves after running it to the end of it's travel the pressure line should jump. Other wise you can take one of the lines off and attach a couple of hose to the disconnected port and the disconnected hose point them into a bucket and have someone start the tractor for a second if the port has flow it's the power, if the hose does it's the power beyond.

There are no markings that I see immediately.

I'm going to pressure wash everything and start doing physical work tomorrow, I'm just trying to think it through before I start actually turning wrenches and wasting fluid.

I was hoping someone here had been through this before me and had pointers.
