240D crank pulley information

Traveling down the highway, I thought for a moment that the gremlin in my 240D (http://mercedessource.com/node/4065) had suddenly gotten chewed up and spit out the rear as, after the brief ruckus, my horsepower suddenly increased and the engine ran super-smooth. That dream was short-lived as my temperature gauge quickly pegged and I realized that I had no power-steering. After I pulled over and popped the hood, I discovered my crank pulley sitting sideways against the radiator, wrapped in a ball of belts and fan blade fragments. My question is this: The pulley is different than I have read about in other posts (http://www.mercedesshop.com/shopforum/showthread.php3?p=610774#post610774). They describe six hex bolts attaching it to the harmonic balancer, as well as having washers. My pulley only has three holes, and any bolts and washers are scattered down the highway. I am not able to find any information or diagrams on how it should be properly re-attached. The pulley has a sharp gash on the edge, and I would like to replace it as well as the bolts and washers. Any help or parts information would be greatly appreciated.
