[s-cars] 93 S4 Steering pump, purchase a seal kit from the dealer

[Ira Deere]

You can easily reseal the ZF Psteering pump.  I resealed my '93 last fall, took me about 1.5 hours first time.  I don't have the part number, sorry.

Dave,

If it is leaking from a round plug with an x on it, yes it can be
fixed.
You will need to replace teh plug and o-ring underneath it, here are
the part numbers from a previous post Tony made:

" "X" plug & the O-ring, pn: 026-145-541

I paid $15 Cdn from local stealer

Quoting some info from this page
http://www.elektro.com/~audi/hydraulic/

"TOOLS AND PARTS NEEDED for the repair. 

A drag link socket is like a stubby, wide, screwdriver. 
Go to a NAPA auto parts store and ask for a 11/16 inch, 3/8 drive drag
link socket. You may need to touch the outer corners to a grindstone,
to narrow it maybe 1/16", otherwise it fits like a charm. 

When you go to NAPA, and the guy behind the counter looks like he is
going to search catalogs for hours, it's NAPA part # NB-95. 


Then go to the Audi parts counter and order the "X" plug & the O-ring,
pn: 026-145-541, before the entire back of the car is covered with
Pentosin :-) 

WORK PROCEDURE for Installation 

Before starting this, with the engine off pump the brake pedal 30 or 40
times until it gets very stiff. This releases the pressure from the
accumulator system. Leave the engine off. 

Clean the area around the "X" plug on top of the hydraulic pump. A
spray can of brake disk cleaner works very well for this. 

If you have an impact hammer, use it and the drag link socket.
Otherwise, use the drag link socket with a ratchet handle - keeping the
screwdriver end completely straight in the shallow groove of the "X"
plug. Loosen the "X" plug and unscrew it. 

Put a tiny bit of hydraulic fluid on the o-ring of the new "X" plug,
and screw the plug into the hydraulic pump. Using the drag link socket,
tighten the "X" plug tight. It depends on the o-ring for sealing, so
you don't have to use brute force in the tightening. 

The Bentley for 89 - 91 100/200 models provides details on replacing
pump seals in the chapter on "Steering"... 37 ft lbs is the spec. 

After making sure all tools are out of the engine compartment, start
the engine and check for leaks around the "X" plug area. It should stay
nice and dry now! "


Hope this helps
Chris
