Mikey:

Check out the pics I posted on the Yahoo photos
section of the Audi-VW Diesel List. Three show my
leaky pump seal and what the pump looks like after the
seal is removed and the shredded old seal. You may be
able to replace it w/ the pump mounted on the car, not
sure. Mine was not since I found the leaky seal when
the motor was being replaced. You need to remove the
timing belt and the injection pump sprocket. (The belt
just has to be slipped off the sprockets after
loosening the tensioner)--no need to remove the other
belts and pull it from the car (unless its time to
replace it, and now may be a good time!). Some here
have reported the pump pulley is hell to get off,
unless you have that $80 special pump gear puller. I
used a general purpose puller (see my pic)and got it
real tight and gave the pulley a good tap w/ a hammer.
Came right off! Then you need to get the old seal out
WITHOUT marring the pump shaft and the recess where
the seal fits. All I can say is that that seal was way
tighter than I imagined. Its metal backing kept
tearing as I tried to extract it. I tried drilling
holes in it and using a full sized seal puller, which
was too big. It finally worked, though after near an
hour messing w/ it (see the pic of the shredded old
seal!). The new one taps right in. Coat its lip w/
diesel before installing. Then install the belt,
tension and set the valve and cam timing. Good luck.
