Seat your pulley back onto the snout of the crankshaft as best you can by hand. If you purchased a longer crank bolt which I *highly* recommend, start threading this in now and pull the pulley on about a 1/4 or 1/2 an inch and remove the longer bolt. Use your old stock crank pulley bolt to pull the pulley onto the crankshaft until the bolt seems to get impossible to turn. Grab your biggest torque wrench and attempt to torque that bolt down to 240lb/ft. I have always stopped at 200lb/ft on my installs and I've never had a problem, so if you can't hit 240 (which I never have), don't worry about it. Now, break the bolt free and remove it.

NOTE: If you did not buy a longer crank bolt, and you are reinstalling the stock pulley, you run the risk of stripping out the first few threads of the crankshaft. This will NOT be fun to fix! Take your NEW crank pulley bolt and thread it in all the way by hand. Torque this bolt to 37lb/ft. Now, we need to stretch the bolt into place. Get your breaker bar and pipe extension, and try to turn the bolt 140degrees past where it is at now, keeping in mind the engine will be trying to turn some and those are degrees you can't count. Again, I always seem to get about 90-100 degrees worth (estimating, knowing what 90 degrees looks like) and leave it as is so don't worry about going crazy here.
