How to replace pump in power steering unit?

    I am trying to remove the pump from the reservoir and replace with a rebuilt pump. My power steering unit has been out of my car for at least 10 years and has been submersed in parts cleaner and sat dry for a few years after that. After adding fluid to it on the car it started grinding like putting nails through a Couissinart. I decided I should replace the pump (You have to separate it from the reservoir)

    So I removed the pulley, removed the brackets and the pressure hose from the rear, but how does the pump come out? Does it "pop" out or is there more I have to do?

    The two studs on the rear of the reservoir almost look like they are part of the pump, but I don't think they are. They have nuts at the base of the studs that look like they are permanently mounted.

    I just don't want to destroy anything taking this thing apart.

    The new pump comes with all new O-rings and stuff.

    Anyone know anything for me?

    Thanks in advance.

    The two studs on the back of the reservoir are what attach the reservoir to the pump. Before you take those off, make sure that the pressure relief valve is still in the pump ( it is in the opening where you should have disconnected the pressure hose from). Then you can take the studs off and gently separate the reservoir from the pump with a rubber mallet or a hammer and a block of wood.
    Do a search, there have been multiple threads on the subject here on v8b.

    Found the studs are very thin & hard to get a good grip with a box end wrench.
    Should you have difficulty, try this:
    Place the box end wrench over the stud/nut.
    Place a flat washer over the wrench. May have to use a couple to reduce the inner opening.
    Hand snug a hex nut over the washers. This will keep the wrench from slipping & skinning the bark from your knuckles.

    Thanks guys. So those nuts "do" come off those studs then. This actually makes much more sense. Thanks for the ideas fellas. It is MUCH appreciated. :TU:

    Ok, I used a 11/16 deep socket and got the studs off. Now what? This thing is so hard to get out. Do I also have to remove the fitting for the pressure hose?

    I tried taking the studs and putting them back in a few threads then hitting them with a leather mallet, then a rubber mallet, then a piece of wood and a sledge hammer. :af:

    What gives with this pump? I must be missing something. :Do No:

    Pressure hose fitting has to come off. Be ready to catch the internal spring.
    Usually get it on the second bounce. Should be able to gently tap the pump from the housing after this.

    Ken the pressure fitting must come out as well be carefull because there is a spring and ball in there.
