C) If the pump has internal leakage or noise because the vane guides
are shot, or the cam is shot, new seals won't help you

Why don't you buy a remanufactured pump or a "new" pump already with a higher pressure? You could call Jeannie or David at 928 Spec.

Because I have three very good pumps of this model, and I would like to use them, and work with what I have. One has alot of mileage and may be leaking, and the other is bone dry with 75k. Another is unknown. I LIKE seeing the inside of these things. Its fun. This isn't rocket science. The details that I ask of you on these issues probably are published somewhere. If they aren't, someone will publish them soon.

Jim Bailey says in this *thread*
I believe that much of the reduced effort is the very late rack but obviously Porsche felt that they needed to change the pump pressure,the lines and the rack to get what they wanted ...All of the better rebuilt racks have seals designed for the higher pressures and the pump bypass can be adjusted shimmed for higher pressure BUT Porsche added power steering cooling lines to help dispurse the heat generated by churning up the fluid.

Don't get me wrong. We ALL DIY when we can. But, if you can fix a pump with symptoms of low pressure, AND the vanes are shot, using only a new seal "kit" plus a 10 mm wrench, screw driver and hammer.... I will send everyone over to you!

Where do I get new vanes? Can I? What other pressure related wear items can we purchase?

Good question. I don't recall ever seeing ZF market vanes at the retail level.

Depending upon which authors terms you use when you go fishing for your parts you may or may not get your answer, however many call the "guts" or working part of the pump a cartridge, some call the vanes vanes, some call part of the cartridge the cam or ring. The ZF (a Vickers balanced vane design) vane pump also shares in the pumping section the "nose" (front casting with shaft bearing) for one side of the chamber and a cap for the rear side of the chamber. Again, I don't recall ever seeing ZF market these retail, at least not above board or through normal distribution.

A few of components of the pump can be easily repaired to "like new" condition if you have the right equipment. Or, as with any other component you could simply replicate it, again if you have, or have access to, the equipment.

A good source for additional information about this pump design can be found, maybe, at Eaton (Vickers).

Again I have strayed away from the post's original topic. I'll plead something along the lines of the Stockholm syndrome at this time and graciously stop here.

Default Tie rod pass side off after rebuild!

I counted the threads and they matched up but after taking the car for a drive the pass wheels is way off. I did the steering rack, MM, oil pan ,ball joint seals, rotors, pads and one tie rod " the pass side. I assume I need to remove it and turn it out a few turns, ? how do i know when its correct or do i need to keep doing this till I get it right. P.S. added the x-pipe the rear axials are out tomorrow to replace the boots tomorrow along with new rotors and brakes.
Lord give me strenght!

I'm jumping into this thread late, just to answer the latest question. Remember - a 928 cannot be aligned while lifted. Once the car is lifted, it needs to be driven for a few miles, so the suspension can settle again. It must be aligned while still sitting on its wheels.
