Komatsu WB93R-8 Main Hydraulic Pump | 708-1U-00163

1. Product Overview
The Komatsu Hydraulic Piston Pump is an axial piston variable displacement unit specifically engineered for the WB93R-8 series backhoe loader. This pump is a direct replacement for OEM part number 708-1U-00163. It is designed to integrate with Komatsu’s advanced "SyncroSystem" hydraulic logic, which matches the pump's output to the operator’s demand for high-speed travel or high-torque digging.

2. Technical Specifications & Performance

3. Key Engineering Advantages
Optimized Flow Sharing: Specifically calibrated to handle the dual functionality of a backhoe loader. The pump ensures that hydraulic flow is distributed evenly between the steering, loader, and backhoe circuits, preventing performance drops during multi-function tasks.

Precision Load Sensing: The variable swashplate design adjusts instantly to joystick input, providing high precision for delicate grading and high speed for loading cycles.

Thermal Efficiency: Internal porting is designed to reduce friction and turbulence, keeping hydraulic oil temperatures low during high-duty cycles like continuous trenching.

Durable Construction: Features high-strength alloy cylinder blocks and induction-hardened pistons to withstand the intense pressure spikes common in backhoe and breaker applications.
