Re: R&R of hydraulic pump bushing
I've rebuilt a few hydraulic pumps to get rid of the ubiquitous leaks. After
spending all too much on Audi seal kits I resorted to Ace Hardware and the
Kohler toilet O-ring assortment box. No kidding, I have had very good luck that
way and none have failed that repair. The most important one is the large
single ring under the aluminum screw in assembly within the reservoir. That is
the one that usually is causing leaks, but is overlooked. Not sure about the
bushing replacement as I've not replaced any, but access seems fairly simple.
Complete removal and disassembly in less than an hour once you've done it.
