I have a 2-70 white I am putting a loader on and I plumed the hydraulic lines to the 2 ports on the left side and they both have preacher am I missing something

He right. Take the front line off and get a 3/8 hex socket pipe plug. Reach in till you find the spot. If your loader is detachable you'll have to jumper those two ports to use the remotes or 3 pt.
 
There's a passage drilled from where the front hose is straight back to where the rear hose enters. That's the normal fluid flow with the plugs in place and not power beyond. The 3/8 pipe plug blocks that passage so flow is through the front hose, through the loader valve and back through the rear hose. From there it goes through the remotes, then the servo valve for the lift. It's back in there a ways so get a plug with the hex socket and put it in with an Allen wrench. I'm going to be doing that on my 1550 soon.
 
King, welcome to YT! I hope this will work for you but I am going to question it a bit. I am not familiar with the 2-
70 White, but Tractordata shows it as being equipped with open center hydraulics. By the way Mike has
explained the connections you are making the valve you are plumbing in for the loader will need to be capable of
withstanding full hydraulic pressure through its return port. Most open center valves are not designed for this. In
the case that the valve is a joystick type designed specifically for a loader there is a slim possibility it may be.
Please give us more details of the loader or valve you are installing. I would not like to see you damage the
valve or the tractors hydraulic system.
 
Good point red. I'm getting a JD 148 that came off a 4020, closed center system, so I'll have to change over the valve. Some can be converted CC to OC but I don't know what I'm getting other than it's a Prince. Couldn't find a number the way it's mounted.
 
Mike, a little more on this. If connected as proposed, the flow will be in series. Which is okay, but when operating a function of the added loader valve items connected beyond the valves return will have their function momentarily disabled. And like I said any function beyond where the pressure returns into the tractor will pressurize the flow route of the external valve. This pressure could be as high as the point of where the tractor relief pressure is set. Like if a cylinder is connected and it?s remote valve is held open past the end of its stroke.
 
I have a 1550 set up like the original poster with a 4 bank open center valve,it has a relief setting as do most any valves these days and the tractor will also bypass even using the
power beyond.I bottom the cylinder out all the time when lower and raising the baler gate.Used it all last Summer baling with no problems.The likely hood of using the tractor remotes at the same time as the Power Beyond remotes is slim.Anyway the tractor remotes won't release pressure on a cylinder even if the tractor is shut off.Have you ever actually run one of these tractors?
 
Traditional Farmer you are correct I have not driven a 2-70, I have driven a couple Olivers a time or two but never to any extent. I apologize I may have given some information that was not 100 percent correct. I was going by how Mike(NWOhio) described how the connection was going to be made. Nothing against Mike but his description may not have been completely accurate in the fact that the power beyond must be providing pressure after it supplies the stock tractor hydraulics and not before. This is a different scenario, again my apologies.
 
Its a little confusing how it works that's why I asked,the Power Beyond doesn't run directly from the pump on those tractors like on a lot of things,it goes thru the relief valve in the hydraulics so if something happens in the Power Beyond it won't blow the pump.Having a relief setting in the external valve set a little lower than the tractor relief works the best as far as I can figure.
