Crank Failure

[Dewayne Waldron]

What do you guys think? Did the ebay crank pully cause my buddies crank to seperate? I think it's the logical answer. Because it had no Harmonic balance. Correct?

I don't have anything as of yet. I'll have to get with my friend and he only took the oil pan off to see the crank. He said it's in 5 pieces !

It is very possible.. The harmonic balancer takes a ton of stress off the crank. Unless the car is a full race app where your trying to remove as much of the rotating mass as possible it is a very stupid mod to do. The crank would have to be very out of balance to cause it to break like that but it is stupid to put a none harmonicly balanced crank pulley on a DD or normally driven car unless it is balanced with the vehicle.. Very fast cars run OEM or fluidampre type crank pulleys... They rarely opt for the lightwieght aluminum ones maily because how high we rev

My thoughts exactly, I just wanted to get some other opinions.
