Willie, there is a key on the crankshaft that the pulley fits onto. So it will only go on one way. Be careful though. With the pulley off, the key can fall out and into the inside of the timing cover. As you're disassembling or before you reassemble, rotate the engine so that the key is on the top of the crank. It should then stay in place for you. Once you remove the pulley nut, you'll be able to see the key/keyway by looking at the pulley hub. That crank pulley nut can be a bear to get off too. Feel free to email me if you have any other questions. ===== Steve VIN 2650 ("Project Delorean") www.projectdelorean.com __________________________________________________ Do you Yahoo!?
