A harmonic balancer consists of two separate pieces the first is the mass which is bolted to the crankshaft shout and the second is the energy dissipating element which is separated by a rubber insulator. This is the most common type of filtering applied because of economics and because it also tends to correct the load power factor as well as remove the harmonic current.
These balancers will use a solid piece of metal for the main hub and have some type of material attached to it for balance.
How harmonic balancer works. This is where the harmonic balancer comes in. The circular device made of rubber and metal is bolted at the front end of the crankshaft to help absorb vibrations. Instead it removes and absorbs unwanted vibrations.
This vibration it absorbs comes from the torsional twisting of your engines crankshaft. In certain engine applications the harmonic balancer is actually part of the engine balancing strategy. Weights are added to the balancer that offset the weight of the pistons and rods.
This is called external balancing. A harmonic balancer consists of two separate pieces the first is the mass which is bolted to the crankshaft shout and the second is the energy dissipating element which is separated by a rubber insulator. Due to the stress and strain that is placed upon the harmonic balancer the unit can sometimes crack or separate.
A harmonic balancer sometimes crankshaft damper torsional damper or vibration damper is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. The How It Works series is meant to take a deep dive into a specific product to give you the best understanding of what is really going on how it works and why it works.

Its purpose is to absorb and reduce harmonic vibrations from the engine as the crankshaft rotates as harmonic vibrations at high engine speeds can cause accelerated wear and damage to the components. This component works with the camshaft sensor to keep engine components operating smoothly and belts running without slipping. The purpose of a harmonic balancer is to dampen the harmonic vibrations that all engines produce.
On many engines the harmonic balancer is integrated into the crank pulley. A harmonic balancer works by removing and absorbing any unwanted vibration caused by the twisting of the car crankshaft and also referred to as dampeners. Car torsional issues regarding vibrations are made by prevalent pulses caused by combustion scenarios.
A harmonic balancer is a front end accessory drive component that is connected to the crankshaft of an engine. The purpose of the harmonic balancer is to reduce engine vibration and in many cases serve as a pulley for drive belts. Balancer Basics The engine in your street car uses a basic elastomer style of harmonic balancer to control the vibrations created while the engine is running.
These balancers will use a solid piece of metal for the main hub and have some type of material attached to it for balance. A harmonic balancer or vibration dampener attaches to the front of the crankshaft of a cars engine. It is designed to reduce the vibrations of the engine both making it quieter and extending its useful life.
The balancer has a metal exterior usually aluminum but is mounted to the crankshaft with rubber which is part of its interior. The shunt filter works by short-circuiting harmonic currents as close to the source of distortion as practical. This keeps the currents out of the supply system.
This is the most common type of filtering applied because of economics and because it also tends to correct the load power factor as well as remove the harmonic current. A rubber isolation harmonic balancer has three components. A heavy cast or machined center portion designed to create mass a rubber isolation ring and an outer pulley.
Just like a flywheel in an engine the center portions mass is designed to add smooth power flow through inertia. A harmonic balancer is a forepart attachment connected to the crankshaft of an engine that decreases the vibrations and mostly viewed as a damper. Its actually a rubber sandwich as the central part made up of rubber and the outside layers are built of metal.
