Subject: crank pulley- unbalanced?


Hi, A friend and I tried to change my '92 900's crankshaft pulley this weekend. We ended up failing, because we didn't have a 27mm socket shallow enough to get between the pulley and the firewall (honestly, I've never even seen one that shallow- how do people do that?). In the process of reassembling the pulley, there was another problem: we broke one of the 3 10mm bolts that holds the AC pulley to the crank pulley. So that bolt is missing the head and about 1/2 of the threads. The car runs fine, but I'm concerned about the fact that the crank pulley is now slightly asymmetrical. Is this imbalance significant enough to worry about it damaging the crankshaft? Also, one more thing: the new belts we put on seem much more audible than the old ones-- they make a sort of whistling/whining sound that I didn't hear before. Is this indicative of some problem (perhaps belts are too tight)? Or is it maybe because the new belts have teeth on them and the old ones didn't? Thanks for your help. John
