power steering pumps: A1 Cardone versus ZF

[PeterBergin at aol.com]

Look in your Bentley, there are a bunch of round plugs that come our,  
underneath are O-ring seals and springs with valves.  It is really quite a  
simple procedure.  You need to buy a 1 inch drag link socket, round the  corners 
off with a grinder.  Use an impact driver (the kind you hammer on)  to 
loosen them.  My leaks were when the O-rings failed.  There may be  directions 
on SJM's site.  If your shaft seal is leaking, you will see  it.  If so be 
very careful removing the pulley mount.  It is easy to  break it if you use 
the wrong kind of puller.
 
I would only use the 11S, however others have used brand X fluids with  
success.  
Good Luck,
 
 
I presume you have a  91 200 20v.  That was the list your post  came on.

What can  be leaking besides shaft seal? I don't understand your statement: 
"If the  pulley seal is not leaking, I would not mess  
with it." Please  explain.

Why did you not rebuild the pump, kit cost less than $20 and takes  about 
an 
hour, piece of cake.  If the pulley seal is not leaking, I  would not mess  
with it.  Done mine twice in  239k,

Several  years  ago I somehow got ZF rebuild pump for around $200
(current price is   400+). Unfortunately it only appears to have lasted
about 15 hours on  the  track, don't have exact records.

Haven't had any leaks until  I started  occasional redline visits in
preparation for a new season.  After a short  time hydraulic fluid
started dripping from the  pump...

I got the  cheapest pump I could get, A1 Carbone from Rock  Auto. So far
found two big  problems.

1. Black paint is  everywhere, including hose connections and  all four
threaded mounting  holes. Brake cleaner somewhat helped.
2. Pump  was primed by something  that resembles Dexron ATF and not the
Pentosin CHF   11S.

Will   see how it works on the car   tomorrow.
