[V8] Questions about Hydraulic Pump

[cobram at juno.com]

There's an oring under that plug that needs to be changed.  I have never
had luck finding the correct size "off the shelf", but the Orings come
with the pump rebuild kit.  However, a new plug with Oring is available
from the dealer and Audi parts vendors.  The ZF part number for the
"Schraubensatz" (screw set) is 8601633109, and was about $2.00 from the
ZF distributor many moons ago.  The Audi part number is (was?)  026 145
541 and were around $8.00 each from the Audi dealer, I opted for the ZF
distributor.  Check first though, part #'s may have changed, or the
Orings might be readily available now...it's been a while.

You may need a new plug though, because depending on how accessable it is
or how tight, you might have to tap it out along the slot lip with a
point or chisel.  Those big slotted 3/8 adapters (looks like a big
slotted screwdriver head on a socket)  they sell at Sear work OK if the
bolt isn't too tight.
