Alternator Clutch Freewheel Pulleys 27415-30010. Equipped with a precision one-way clutch mechanism, the vehicle automatically buffers speed differences during start-stop, gear shifting, and acceleration/deceleration, isolates reverse impact forces. Significantly reduce belt deflection and tension vibration, eliminate transmission noise and shaking issues, ensure smooth operation of engine accessory transmission system, and enhance driving experi. Relieve belt load and tension wheel pressure, avoid belt slippage during high-speed shifting, significantly improve the overall life of the transmission belt, tension wheel, and generator, and reduce. Reverse idling does not generate reverse current, stabilizes the output power of the generator, maintains a reasonable speed under idle conditions, stabilizes the efficiency of the generator, and adap.
