By the way, you don't really need to buy a new crankshaft pulley bolt. I wish I read the service manual before I bought one. (oh well its $20) But anyways, the manual says to measure it and if its not stretched beyond certain length (specified there but I don't remember) than you can reuse it. Also, most frown on using flywheel lock tools to prevent the crankshaft from spinning when you try to loosen or tighter the bolt but the manual instructs to using one. I made my own tool though - using a pipe base, few bolts, and a steel bar to hold the pulley in place. I think it cost me under $30, all from Lowes.
