Why Do I Need A Performance Harmonic Balancer / Crankshaft Damper?
The installation of any performance parts that increase the engine's power output or torque, such as intake, camshafts, rods, pistons, flywheel, flexplate, fuel pump, injectors, exhaust system, or any ECM changes, typically will increase in torsional vibration magnitude and frequency. These performance upgrades also increase torsional vibrations above a level the OEM damper was not designed to handle. A stock harmonic balancer typically is only tuned for a 50hz peak variance at a particular power level. In addition to previously mentioned performance upgrades, if you alter any of the engine's rotating assembly parameters, it may leave your critical engine components unprotected when torsional vibration is at its peak. Signs that the OEM stock vibration damper is failing: The bonded rubber on the harmonic balancer is now cracked, and the bulging or missing rubber between the hub and outer ring is missing. Age and repeating heat cycles have caused the rubber to degrade. The OEM rubber is also sensitive to solvents and cleaning compounds. Subjecting your damper to these chemicals accelerates the degradation of the damper compounds.
Fluidampr dampers utilize a unique viscous fluid, which, unlike rubber, is very thermally stable, able to withstand the test of time, and will NEVER wear out in a performance application.
Signs that the OEM stock vibration damper has failed:
- A collective failure will be the outer ring separating from the hub causing damage inside the engine bay.
- A noticeable increase in the level of in-cab vibrations.
- A wobble of the damper is apparent during engine operation.
- Dampers outer ring separating from the hub.
- The outer ring of the dampener has cracked.
Due to the countless combinations of performance upgrades possible, the simplest and most cost-effective solution for controlling dangerous torsional vibrations is to install a Fluidampr high-performance sport compact viscous damper on your engine. By design, Fluidampr viscous vibration dampers protect your engine from torsional vibrations across a broad range of frequencies, engine RPMs, and power levels. A viscous vibration damper also continuously self-tunes in real-time throughout the RPM range to adapt to your following engine modification. The earlier a Fluidampr performance damper installation takes place, the more you will benefit from its protection, performance, and the ability to ensure long-term engine life.
What exactly does a Harmonic Balancer Do?
The harmonic balancer's job is to control the destructive crankshaft torsional vibrations. These vibrations are produced with each engine's power stroke during the combustion process. The power cycle of the engine generates a twist and rebound effect upon the engine's crankshaft, which causes torsional vibrations or harmonic waves which can be transmitted from the crankshaft to any metal engine or driveline component. The torsional vibrations are the end-to-end twisting or rebound motion exerted on the crankshaft during each power stroke. A torsional harmonic balancer controls these forces and allows for increased valve train and timing efficiency. The other benefits obtained by installing a viscous crankshaft damper are a reduction in the wear of critical engine components such as main bearings, oil pump, drive-train, and, ultimately, the crankshaft itself. The failure to effectively control these dangerous torsional vibrations can cause catastrophic engine failure.
