6660771Bobcat Excavator Pump Coupling

Description

The 6660771 Bobcat Pump Coupling is an OEM coupling for compact excavator hydraulic drive applications, supplied in the six-bolt configuration. It sits between the engine flywheel and the hydraulic pump, transmitting torque while absorbing the torsional vibration and shock load that occur at startup and under changing load.
Pump couplings are wear items. Once the element hardens or cracks, vibration and misalignment pass straight through to the pump bearings, shaft, and seals. This is the factory component, dimensioned to fit the original mounting without modification.
