I disagree. Not all engines have harmonic balancers. Some engines are internally balanced, like the I4 vw's. The stamped pulley that turns my water pump and alternator is not a balancer. Furthermore, the harmonic balancer on my Audi has belt grooves in it. The Chevy v8s are externally balanced with a HB, and much notice is given to this fact in GM repair manuals. If every motor used a HB, GM wouldn't go out the way to call attention to it. > > re: All engines have harmonic balancers ... > > ... and they're not somthing that's an aftermarket bolt-on > improvement.
