agree with ben

Honda has a very inexpensive crank took to remove this bolt its like a big hex nut that fist inside the crank pully it wont damage the pully or crank...


FYI ben maybe the tranny is still connected to the engine ? just a thought.

If all else fails get a Big Freaking Air gun ! But the best bet is to get the Crank Wrench Snap has them as wellas some parts stores not that pricy and its a good tool to have.
