One New Aftermarket Replacement Disc Damper (Coupling Clutch Plate) for Komatsu Excavators

This disc damper -- also known as a coupling clutch plate or disk damper -- connects the engine to the hydraulic pump drive on Komatsu PC-series crawler excavators powered by the SAA6D114E-3F engine. It dampens torsional vibrations and transmits torque smoothly between the engine and hydraulic pump, reducing rotational shock loads and protecting both the pump and drivetrain from premature wear. Constructed from high-strength steel alloy with a precision 16-tooth coupling design.
