RD548-42630Kubota Coupling

Description

The RD548-42630 Kubota Coupling is an OEM coupling for Kubota compact excavators, in a 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.

Couplings are wear items. Once the element hardens or cracks, vibration and misalignment pass straight through to the bearings, shafts, and seals around it. This is the factory component, dimensioned to fit the original mounting without modification.
