Ya... I had to remove the main pulley to do the waterpump job on my '85
waterboxer.  Not too terrible of a job.  The pulley has holes in it that you
can stick a hefty chisel through that will keep the crank from turning while
you reef on that big bad nut.  You'll definetely need at least a 1/2" drive
for your socket and either a breaker bar or a cheater bar.  The manuals
recommend replacing the main seal when you reassemble but after digging and
poking for a while, I gave up on that and after 15K miles have had no
resulting problems.  While you've got everything apart have a good look at
little-- what are they about 1" ?-- water pipes.  Replace them now if they
show much corrosion.  The whole system fits together like a jigsaw puzzle
and you're not going to want to pull it apart again any time soon.  I used a
little gear grease to get some of o-ring fittings to slide together.  Good
Luck.
