Now that I think of it, the reason that I own a big 40 Gallon air compressor is because of a crankshaft pulley! I couldn't get one off of my Spitfire 10-12 years back.

I remember using a 4' pipe on a few Miatas, and one of them was so stubborn that we had to throw a bunch of penetrating oil and heat at it!

This one was quite easy in comparison. All done, btw.
