The main drive pulley of an engine; mounted on the fromt end of the crankshaft. Harmonic balancers are weighted to keep the crankshaft balance in order to reduce vibration.

Frank: The dang harmonic balancer is frozen to the crankshaft!
Allan: Probably gonna have to use a harmonic balancer puller, Frank.
Frank: Wow! They actually make those?!
Allan: Yep

Harmonia 

a) A Greek, immortal Goddess of harmony and concord.
b) An Italian Mistress that balances internal harmony though external pain.

Sometimes the only way to reach emotions is though physical pain. Mistress Harmonia is good at that!
