    Even tried a new pump...

    With new pump:
    No air bubbles. ..I guess it's bled now...
    With wheels off the ground and engine running, I turn the wheel back and forth and it is clearly easier than without the engine running...there must be "some" assist. ...
    Put it back on the ground and it's like manual steering. ....

    Pulling my hair out on this one...
    Any thoughts?

        Kinda inpossible to put the hoses on wrong...
        No plugs...

        This really should be easy...it's just a stupid pump.....
        Everything was fine until I endeavored to fix my leak lol...!

          gotcha

          ok, so its easier with the wheels of the ground and the engine running then with the engine off, correct?

          meaning it does assist "some" but not as much as you want
          are these pumps adjustable?

            No...once the wheels are on the ground, it's like no assist at all...
            I only can feel assist with the wheels off the ground...so it must not be very much at all...but it is noticeable. ...

            But back on the ground it's like zero...

            with the wheels of the ground, and the engine off, is it the same or harder then with the engine on?
            at some point, we need to perhaps quit looking at the pump and start looking at the steering box?

            have you verified there is pressure on the output hose of the pump ?

              I've been bleeding and re-bleeding, and testing and re-bleeding all day it seems...ugh.

              On the ground it feels the same engine on or off...
              Everything worked fine prior to this...I don't know what could have happened to the box...?

              why did you pull the pump?


              would it be possible you got one from a magnum on an LA and its running the wrong direction?

                I pulled it to replace a leaking seal...
                And the new pump I'm currently trying to make work it's for 74 to 76 abody mopar. ..it's an exact match to my old one...

                So freaking exact that it doesn't work either! Lol

                  Is the procedure to bleed the pump just turning the wheel back and forth lock to lock a few times? Could you take box to a trans shop and have them bench test it for 1200 psi pressure? Read this article on how to reduce your pressure and you'll be able to increase it too.

                    Yes....that is the basic procedure. ...and I've done a LOT of it.....
                    Cool link!

                    Well, what about this thougt...what if there is an obstruction and that caused the seal to fail?
                    Pressing fluid out the only way it could go

                      Could be. ...I guess I'm going to have to go back to square one. ...
                      Pull it off...make sure the spring loaded valve moves freely, make sure there's no obstructions in the lines...etc.

                      Damn thing is kicking my ass...
                      If it was easy, everyone would do it!

                      I want to wrap this up because my awesome new electric fans and controller are sitting in my garage waiting for install.
                      This and the fans will wrap up this year's projects and I can get back to driving and enjoying her!

                      When I finally do get this figured out I'll let ya'll know what it turned out to be. ....

                      Of course, if anyone has any more ideas, I'm all ears!

                      A functional pump will bleed itself of air with only a couple of turns back and forth.
                      Under your circumstances I'd be checking to make sure my pressure side hose wasn't collapsed inside from moving it around during the swaps.

                        I kinda thought it shouldn't be this hard....lol
                        That's something I'll check for sure...
                        My high pressure hose, the fitting wouldn't screw into the port on the new pump, so I swapped out the port from my old pump to the new one... They pretty much looked identical, but I wonder if that's the issue...?

                        This is the port I swapped. ..

                        20180803_175244.jpg

                        I would gladly just buy a new power steering hose and use the new port that came with it but I don't know what type of fitting that is...

                        The pump is a Saginaw PS6021

                        OER PS6021

                        The trick is getting the correct hose for my car/application. ..
                        There are a zillion different types. ..

                        Take it in to a hydraulics shop and have them make hoses for it
                        They prolly have the fitting too

                          Good idea....there's actually a shop right near my work called "The Hose Man"....
                          Monday at lunch...!
                          I bet that's the problem. ..

                          Not on a mopar, but i spun up a pump with my drill,the oil sure flies when its working right.

                          I also remember when i re sealed my power steering box in the power wagon, it was a battle,like it airlocked.
                          Running it with the cap off and not going lock to lock was the ticket. It would aerate the fluid if i went to lock.
