You pry the trangular flange off the shaft and use a soft mallet (or a BFH
and block of wood) to drive it out of the pump half after taking the halves
apart.  You need to fish out the old seal from the pump body.

Don't you have a Bentley?  Its on pages  48.27 thru 48.36.  Best write-up
of pump rebuild I've seen.
