indeed. still, very bizarre that this happens. cloudsurfer - harmonic balancers are normally tuned to damp the natural frequency of the crank. who designed the damped pulley, & do we think it's tuned?
i wish i could get that broken crank under a microscope.......still, with it being sintered, it would be a lot harder to tell exactly what happened.
