This device must be interference fit to the crankshaft in order to operate in an effective manner. An interference fit ensures the device moves in perfect step with crankshaft. It is essential on engines with long crankshafts (such as straight-8 engines) and V8 engines with cross plane cranks. Harmonics and torsional vibrations can greatly reduce crankshaft life, or cause instantaneous failure if the crankshaft runs at or through an amplified resonance. Dampers are designed with a specific weight (mass) which is dependent on the damping material/method used and the freedom it affords the mass move allowing to reduce mechanical Q factor, or damp, crankshaft resonances. 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 harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator, water pump and other crankshaft driven devices.\",\"question\":\"is crankshaft pulley and harmonic balancer the same thing\"}","display_format":"text","language":"","answer_status":"published","assets":[],"source_url":"https://github.com/google-research-datasets/boolean-questions","history":"initial import","indexing_mode":"index","subproblems":[],"grids":[]}
