Remember you're dealing with an oil film in the thousandths of an inch.
Even the slightest torsional movement of the crank caused by a harmful harmonic can break the film and create metal to metal contact...
One bearing spins and under load more will typically follow..
My question as it always has been is the theory behind removing the harmonic balancer...
What empirical data shows any performance increase?
To me just a very costly and dangerous "urban legend" !!!
