Vibration dampers are crucial elements of any engine. Vital to the engine and critical accessory systems, dampers help to minimize harmonic vibrations that can damage motor parts and compromise performance and efficiency.
At PartsGeek.com you will find vibration dampers from top brands like A1 Cordone, Febi, Genuine, Scan-Tech and USA Industries, as well as plenty of options for Original Equipment and Original Equivalent parts.
We pride ourselves on providing excellent customer service, speedy delivery and an impressive selection of quality parts at a fair price. And, our 30-day return policy helps us to guarantee that you will get the part you need to get your engine running like clockwork.
An engine vibration damper is a simple auto part with many names; vibration damper, crankshaft damper, harmonic damper and torsional damper are probably just a few common aliases.
This crucial piece is typically made of rubber and metal. Bolted at the head of the crankshaft, it helps to absorb the vibrations produced with each firing of the cylinder. Vibration dampers are also typically connected to the crank pulley, helping to power onboard accessory systems such as air conditioning.
The metal portion of the engine vibration damper provides the torsional and shearing strength needed to withstand high speeds and force. Meanwhile, the rubber within the pulley absorbs shocks in order to ease strain and wear on the crankshaft.
The price for an engine vibration damper will vary depending on the make and model of the vehicle, as well as the material and design quality of the specific part. Most of the dampers available on PartsGeek.com fall within the price range of $30 and $150.
As engine cylinders fire they move up and down at high speeds, generating torque that transfers to the crankshaft. That is, the crankshaft helps to convert the raw combustion power produced by the engine into the rotational force needed to eventually get the wheels moving.
The forces needed to produce this much horsepower are huge, and the crankshaft is engaged every time a cylinder fires. This force has the potential to cause vibrations in the crankshaft itself. When the crankshaft vibrates at certain frequencies it can begin to resonate (or ""harmonize""), intensifying the shaking dramatically (hence the name ""harmonic damper"").
When vibration dampers begin to fail, the engine can begin to vibrate excessively, potentially cuasing issues such as a damaged crankshaft or displaced serpentine belt.
There are several signs and symptoms of a compromised vibration dampers:
- Engine resonance: one of the earliest marks of a weakened damper is intensified engine vibration, particularly at certain crankshaft frequencies. When dampers deteriorate, they may not be able to effectively absorb shock, increasingly the likelihood of harmonic interference.
- Misaligned timing marks: many balancers are made up of two pieces of metal separated by a layer of rubber capable of absorbing vibrations. Timing marks are stamped onto the outer portion of the pulley. When misaligned it can become especially difficult to time the engine properly.
- A separated vibration damper: the rubber portion of this auto part is unfortunately prone to dry out, crack and wear out after consistent use. In extreme cases this can lead to the complete failure of the vibration damper, as well as engine accessories such as air circulation systems.
