Super M hydraulics

I've posted a couple times on this. Replumbing hydraulic hoses. My Super had what I would call old tree valve mounted just to the right of bell housing. I've done away with it and planned to install valves back near seat with hoses for auxiliary. I had planned to run loop from pump to reservoir. Then tap my pressure line to my valve from left rear port off reservoir. Put my return line into fill tube. I thought that's what I had read on here in the past.

I mentioned that in a post and someone suggested tapping the two existing lines instead. Another post Barnyard (hope your reading this) made sense in saying that wouldn't work. Now I have looked over my old lines which are no longer on the tractor. Both had T fittings in them that supplied that old valve. I'd say it had been that way for 20-30 years before I got the tractor.

So now I'm confused. How should I do this? Can someone submit diagram or picture of such.

Thanks guys. I could put it back with Ts like it was but now wonder if that is right.
 
The original factory design used a T in the suction and a T in the pressure line between the pump and reservoir to feed the christmas tree valve. The valve then feed 2 way flow to the rear remotes. That is how it left the factory and how the system is designed to work. The operators and parts manual ckearly show this. If someone wants tonsay otherwise they dont know their a** from a hole in the ground. It is a basic hydraulic system with kiw volume flow.
 
Both my Super MD and my Super MTA diesel are plumbed the way yoursvwas originally and both hydraulic systems worked flawlessly.
 
On my belly pump systems,I run a hose from a port to a spool valve,return the oil back to the belly pump via the drain. Tie/secure the lever back to continuous flow. This has worked perfect for years. My tractors with mag pumps are set up similar.
 
Thanks Jim. That lets me know what I had was factory. That's a good place to start. I've never seen another one so I didn't know if someone rigged something. So I can put it back just like that except run to a spool valve. Got it.
 
I may be guilty of what Jim is implying, however all I know is that in a open center system the high pressure supply from the pump needs to be contained...no tees or routing through a reservoir....all the way to the valve that supplies the remote hydraulic operation you are needing. AND...UNDERLINED...the high pressure supply MUST have a method to relieve an over pressure situation through a relief valve that can spill back to the reservoir by a separate passage. Whether that function is integral to the remote valve or through an external pressure relief which could be confused with a tee. Looking closer at the IH online parts list it looks like the relief function is inside the reservoir. Just don?t want you to over pressure your pump and break it or the cam gear in the engine. Does the reservoir in the link resemble the one you have, having an external lever? If so what you are proposing is probably acceptable.
Super M hyd. Reservoir
 
Yes. That's what I have. I rebuilt it and replaced a number of springs and ball valves and worked on the trip mechanism in it. Before I had to lock it in place because any increase in pressure would trip it.

I think I got this. When lever is engaged on this reservoir the pressure line is just that with a pressure check valve in this box. Therefore I will have pressure to my auxiliary valve as long as it stays under that rated pressure. My return will T back in the suction line as it did before. Even that lever is not engaged or trips the reservoir simply allows fluid to flow unhindered.

Thanks guys for clarifying what to do.
