Description
The 527-0742 Caterpillar Hydraulic Pump Flange is an OEM hydraulic pump flange for Caterpillar C7.1 engines in excavators, material handlers, and forestry machines. A flange bolts to the engine flywheel and engages the pump hub, transmitting engine torque to the hydraulic pump while compensating for misalignment.
Couplings are wear items. Once the flange wears 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.
