Sorry J_J but a PB plug on a hyd valve on a JD 302 which came from factory with closed center hyd's positively will not operate correctly.
Will it work?

As I previously stated a PB line on a CC hyd system such as a JD 302 will not allow hyd's to operate correctly. Please post your hyd schematic.

Do you know for sure that the FEL valve is strictly a CC valve?
I simply said that if the valve is convertible what was necessary to convert the valve.
He is asking about the valve on the FEL anyway, which could be either.
If the valve on the FEL is a CC valve he does not have to modify anything.
If the FEL valve is open center and has PB port, then he needs what I said.
Enough now. Da**

J_J as I stated a PB valve with or without a plug will not be correct on a JD CC system PERIOD & you stated "PB adapter with plug" or CC valve. I'll make a wager with you that a "PB adapter with a plug" installed in a FEL control valve will cause a JD 302 hyd system or any other JD with CC hyd's to heat & cavitate!!!!! I'm relatively positive a hyd valve on a 35 HP Case tractor will be open center.

Have you ever hands on diagnosed JD CC hyd heating & cavitation problems?? I did for over 10 yrs as a JD dealer service manager.
Enough now DANG!!!!

You mean that I can not make an open center valve into a CC valve by using a PB adapter and a plug, or a CC plug.
Da*****, I sure thought I could, and please explain why it will not work.
I just know you are going to try.

If an OC adapter with a plug installed where hose is intended to fit will convert a spool valve to CC then why did engineers fabricate a CC adapter why not just install a plug? Notice the absence of the seal on 12C which is an open center adapter vs seal(parts key 10) on CC adapters(12A & 12B). Maybe the older type valves(60- late 80's) that I had experience with are different than convertible(oc io cc & vice-verse) valves built today.

I am assuming there are no hard feelings between you two. Just assertively stating your opinions.
With that being the case, I am enjoying the read. I will surely learn something.
Tx Jim, I do not see an obvious place to install Pump or tank hoses to the valve. Do you recall where I should tap in or do you have a diagram? The pump is in front of the engine. It has hard metal lines going back to the transmission. The lines have treaded connectors at the pump but no obvious connection at the transmission.

No hard feelings on my end but I am hard headed. Please post a photo or numbers stamped on the valve.

Please accept my apology.
After thinking more about PB adapters which came into wide use after I left dealership and I determined I was thinking incorrectly. Plug(parts key 12C) in photo I posted earlier isn't a PB adapter but simply a plug utilized before PB adapters were widely utilized.:mur::mur::mur:
After viewing close up of true PB adapter I see it has same type seal(encircled in blue) that if used in a CC configuration can fail causing CC to revert to OC. This seal that can fail on a CC adapter plug is what had me mixed up as I've previously in yrs gone by diagnosed several of their failures.
Again I apologize,Jim

Tx Jim and J-J,
Thank you for your responses. I do not have the valve. I am trying to decide whether or not to buy the loader, if I can make it work. The seller is 100 miles East of me and my tractor is 120 miles West of me. When I first posted this thread the tractor was here at my home. I get form the previous posts that I will be able to make the loader work without buying a new valve. THANK YOU both J_J AND Tx Jim!
