Thanks all. So I ran back into battle and I return to you defeated. But the war's not over. Couple questions if anyone could help:
I got ahead of myself by asking about how to pull the crank pulley out, but I should first be asking how to loosen the nut (or is it a bolt?). I tried putting a large screwdriver through the cross drilled holes of the crank pulley, against the crankshaft body itself, to keep it from turning (correct strategy?). Next, tried a crescent wrench and then a pipe wrench to turn the nut, that thing is NOT budging. I didn't want to strip it, so I stopped.
I'm assuming I should buy a socket and use a breaker bar? Looks to be 30 mm. If this is the way to do it, I assume it's the same way you tighten it back up?
Next, as @DannyP mentioned I need also to loosen or remove the alternator/generator pulley (I think because otherwise the belt will fight me even if the crank pulley is off). How is this pulley loosened? There's nowhere to do the large screwdriver trick to keep it from spinning...
