Part Description & Details

Replacement harmonic balancers are quickly becoming a hot item for today's car owners. The reason is Harmonic Vibrations which can lead to a variety of mechanical failures.

"Harmonic vibrations" are specific and repeated vibration patterns which pass through an object. In today's cars, such vibrations result from the combustion of the air-fuel mixture. Each time a cylinder fires, the connecting rod pounds the crankshaft journal as the force turns the crankshaft, causing energy to be dispersed throughout the engine. Multiply this by the number of cylinders (with variations in engine speed) and you have what is commonly called harmonic vibrations.

Some of the warning signs of harmonic balancer failure in a vehicle are:
  • A leaking front main seal
  • Visible deterioration of the rubber between the balancer hub and outer ring.
  • Visible cracking or warping of the balancer hub or outer ring.
  • Excessive engine vibration.
  • Slipping, squealing drive belts, belt damage, accelerated belt wear or frequent belt replacement.
  • A highly polished spot on pulley grooves (warped balancer).
  • Elongation of the balancer keyway or wear on the balancer hub/crankshaft.
  • Alternator, power steering pump, air conditioner or water pump failure.
  • Engines that do not run properly when adjusting the timing, or poor performance and irregular idle.
