A little hammering back and forth on the pulley was enough to break the
thing loose and allow it to come right off. I just didn't want to resort
to the big hammer prematurely, but it turned out to do the trick just
fine.

There was indeed some of the green threadlocker on the pulley (or the
gear, more precisely) where it mated with the shaft. I imagine it may
have dripped from the bolt onto the pulley, just as Fred suggested.
Thanks!

Looking at the torsional damper in the pulley, I see a lot of small
cracks, with a couple of little chunks missing. The back face looks much
better. At what point do you decide to get a new pulley? I'd rather not,
but I haven't put the thing back together yet, so this is my chance.

After getting the pulley off, I moved on to the crankshaft seal, which
was much more difficult to get out than expected. I foolishly tried to
remove it without a power drill, using a pick, vise grips, and a pry
bar. I ended up calling Gurdev to come over (with his drill) and take a
look at it, and with enough drilling and prying we got it out. Thanks,
Gurdev, for your help and for the use of your tools! The list comes
through again.

Finally, I worked through the crank torque problem again and am
convinced that you must consider the extension length and shoot for the
338 ft-lb number at the bolt. In my case that means 196 ft-lbs at my
torque wrench... and that if you used a torque wrench shorter than three
feet or so with the 2079 extension, you would apply more torque than
that. I suppose you'd rather be over than under on this job, so as long
as nothing broke, I would think it's okay. If anyone cares to discuss
the torque issue and free body diagrams further, I would be happy to do
so off-list, since this thread appears to be a familiar one to many.
