My Power Steering Pump Rebuild Thread

[sshanky]

Hi guys,

I'm going to try to rebuild some power steering pumps. I have a w116 that had a leaky pump, and after one bad one, I found one leak-free one last year. However, it's starting to leak, probably from the back seal. In the garage, I have two pumps. I have the front seal and the seal kit, so I'll start with the 82 bar one, which I'll put into the 300SD, replacing the Vickers that's in there. Then, maybe I'll rebuild that Vickers and sell it.

here is the first one I'll work on, the older leaking one from the 300SD (82 bar) before power washing:


and one from a 300D (65 bar). Here are both of them after power washing:

The silver one is the 65 bar and the dark one is the 82 bar.

Here are the pulleys (the one on the right came off the 82 bar, but I can tell that if I use that one it will not line up with the current belt in the car, so I think I will need to use the other pulley, or else the one that's currently in the car:


Here is the 65 bar ZF pump:

And Here is the 82 bar ZF pump that I'm going to try to rebuild:


I'll post more later. Any thoughts would be appreciated!
