RE15018 is a damper assembly replacement spare part from the JD agricultural facrm machinery equipment spare parts.

Function: This vibration damper assembly is mounted on the engine crankshaft, primarily serving to reduce torsional vibrations generated during crankshaft operation. Torque pulses generated during engine operation cause torsional vibration in the crankshaft. The RE15018 absorbs and dissipates this vibrational energy through its internal damping mechanism—such as rubber or elastomer materials—reducing vibration amplitude. This protects the crankshaft and related components, enhances engine smoothness and reliability, and extends engine service life.

Structural Features: Typically composed of two parts—a pulley and a damper. The pulley connects to the crankshaft to transmit power, while the damper section incorporates damping elements (e.g., rubber). When torsional vibrations occur in the crankshaft, these damping elements deform to absorb and dissipate the vibrational energy.
