my crank pulley why does this keep happining?
 

ok this is the second crank pulley that i have some how destroyed. this one was on for about 100 miles its off my 94 i had this happen before but this time it went through the timming belt cover. i oraderd a new one piece pully for motorsport wharehouse i hope it holds up. why does this happen has anyone else had this happen to them. ill try and post a pic to show you what i mean. both times the pully seperated its self from the dampining material. is something wrong with my svx or does this happen a lot i really run this car hard maybe thats what is wrong.

another pic

one more cause the last one sucked. has anyone used the onpiece unit from motorsports wharehouse just wondering how it worked out ...:)

I have heard of this being a problem before, but not in 100 miles. Seems like an awful short lifespan. The one-piece should hold up fine.

yeah i havent heard of this happining before the 94 had 107,000 on it when i pulled the crank pulley off i just dont understand. hopefully someone has had a simmaler issue and knowes whats up because i dont want this to happen agian it happend at around 140 150 mph sounded like hell maybe thats why i dont know my last one blew off compleatly at around 6,500 rpms maybe its the high revs i dont know.

I just put Dayles one piece stock size pulley on the wifes svx. So far it is fine.
Her pulley separated too but it only squealed alot - it did not move back far enough to destroy the belt cover. Even as it was separated and the car was running it only moved back and forth about 1/4 inch while I revved the engine.

Maybe you have a belt alignment problem or are putting the belts on too tight?

I'm taunting the svx gods with this but I have yet to have a problem on my svx with 210k on the stock pulley.
