What is the purpose of the elastomer rings in a harmonic balancer?

The elastomer rings are designed to absorb torsional vibrations generated by the crankshaft. This dampening action helps protect the engine from damaging harmonics, leading to smoother operation and longer component life.

How do I know if I need to replace my harmonic balancer elastomers?

You should consider replacing the elastomer rings if you notice signs of aging such as cracking, separation, or hardening of the rubber. A worn-out elastomer can reduce the effectiveness of the harmonic balancer.

What do the '70/60/70' durometer ratings mean?

These numbers refer to the hardness of the individual elastomer rings, measured on the Shore A durometer scale. The specific combination of 70, 60, and 70 shore A is chosen by ATI to provide a particular level of vibration dampening and durability for certain engine applications.

About this part

Product Details

This is the ATI 3-ring elastomer kit, part number 918980-76. It's designed to replace the rubber dampening rings within ATI Super Harmonic Balancers. These elastomers are crucial for absorbing torsional vibrations from the crankshaft, which helps protect your engine from damaging harmonics. If your current balancer's rubber rings are showing signs of age, like cracking or separation, replacing them with this kit can restore its effectiveness.

This specific kit is the '3 Ring - 6 - w/70/60/70' configuration, indicating the size and durometer (hardness) of the three individual elastomer rings. The durometer ratings of 70, 60, and 70 shore A are chosen to provide a specific balance of vibration absorption and durability for certain engine applications. Using the correct elastomer kit ensures your harmonic balancer functions as intended, smoothing out engine operation and prolonging the life of critical engine components.
