One of the first symptoms of a potential problem with the harmonic balancer is engine vibration. The harmonic balancer is specifically designed to absorb harmonic engine vibrations as engine speeds rise.
How do you remove a harmonic balancer from a Chevy truck?
Remove the lower drive pulley from the harmonic balancer. Chevrolet pulleys use three bolts to hold the pulley to the face of the harmonic balancer. Remove the three bolts with a wrench, then pull the pulley off of the harmonic balancer. Remove the harmonic balancer’s single retaining bolt.
Where is the lower pulley on a harmonic balancer?
The lower pulley is bolted to the front of the harmonic balancer. This pulley transfers the energy produced by the crankshaft to the engine’s accessories, such as the power steering pump, alternator and air conditioning compressor, via a number of belts.
Where is the single retaining bolt on a harmonic balancer?
Remove the harmonic balancer’s single retaining bolt. The retaining bolt is located in the center of the harmonic balancer and is used to hold the harmonic balancer to the end of the crankshaft.
The most common symptoms of a bad harmonic balancer include:
- Engine Vibrations. The harmonic balancer’s job is to dampen vibrations applied to the crankshaft.
- Noticeable Harmonic Balancer Wobble.
- Unusual Noises.
- Illuminated Check Engine Light.

What holds the harmonic balancer on a car?
The harmonic balancer is attached to the crankshaft. It is made up of 3 parts: the hub, the rubber dampener, and the balance ring. The hub is in the center. The balance ring is made of heavy metal, and typically serves as the crankshaft pulley (which drives things like the A/C and alternator).
Can you drive a car with a broken harmonic balancer?
It’s not okay to drive with a bad harmonic balancer. The bouncing crankshaft will wear on the main bearings. It can also tear up drive belts and possibly come apart posing a danger to people and property.
