I had a little adventure coming home from the PA/NJ MN12 meet the other day. I was a few miles from home, accellerating from a stoplight at about 1/2 throttle when I heard what sounded like pebbles in a tin can. I immediately thought it was detonation and let off the throttle. Next I heard the sound of metal breaking and grinding and the car had a trail of smoke pouring out behind it as I went down the road. The motor lost all power and I figured I blew the short block. I put the trans in nuetral and costed into a parking lot that was luckily right next to the road.
When I lifted the hood, I was happy to find that it was only the belt that had shredded to pieces and caused all the smoke. But upon futher investigation I found that the bearings in the pulley on the blower bracket failed, and the pulley siezed up and broke. That in turn is what shredded my 8 rib belt. The were tiny metal pieces and dust all over the engine bay.
By the time I got the car towed home I didn't have time to pull things apart because I was already a day late in getting back up to school. I don't think is that bad, but untill I get things apart, I won't know for sure.
Does anyone know if that pulley is made to come off the bracket when the bracket is unbolted from the engine. I am hoping maybe the pulley is made to be replacable in the event that it fails.
Its defintely better then rebuilding the shortblock
Since I am away at school, there is no rush to get the car fixed and up and running anytime soon. This will give me time to pull things apart and check some stuff out. Probably won't be started up untill spring/summer.
Pic: The pulley that seized and broke is the one on the bracket to the right of the blower, and under/slightly left of the alternator. Sorry, no pics of its current status.
