I have the bottom half of the BBC removed but now I'm trying to get the top half off of the crankshaft. The manual says to crank down on the special bolt, which I believe is the 5/8-11 bolt that another source references, and it should come off. I tried using a bolt but I'm afraid of doing damage. Is this really the way to do it? I've also tried using a puller with the arms around the top top plate with the elongated hole to no avail. The arrow in the image points to the threads on the top half of the clutch where the bolt would thread in. Any suggestions? I don't need to worry about keeping it because the engine is going to be used for something else but I don't want to damage the crank.
