One New Aftermarket Replacement Coupling Insert for Caterpillar (Cat) 330-Series Excavators
This coupling insert is used in the engine-to-hydraulic-pump drive assembly on Caterpillar (Cat) 330-series excavators. The elastomeric insert fits between the coupling halves, transmitting torque while dampening vibration and accommodating minor shaft misalignment, helping protect the hydraulic pump and engine from shock loads and premature wear. Replacing a worn or cracked insert promptly helps maintain hydraulic system performance and prevents damage to surrounding drivetrain components.
