Hitachi EX60 EX60G EX60SR Main Hydraulic Pump | Rexroth A10VD43

1. Product Overview
The Rexroth A10VD43 hydraulic pump is the factory-standard power unit for the Hitachi EX60, EX60G, and EX60SR (Short Radius) models. This tandem piston pump is a direct replacement for OEM part numbers 4194446 and 4213029. It is engineered to provide independent flow to the travel and implement circuits, ensuring smooth, simultaneous operations even under heavy loads.

3. Key Engineering Advantages
Tandem Design for Precision: The double-pump configuration allows for synchronized oil flow to both tracks and the boom/arm, preventing the machine from "veering" during travel while the arm is in motion.

Load-Sensing Compatibility: Specifically designed to work with Hitachi’s hydraulic control logic, providing high power for heavy digging and lower flow for high-speed travel, optimizing fuel consumption.

Proven Reliability: The Rexroth A10 series is world-renowned for its durability. Its high-strength swashplate and hardened piston slippers are built to handle the constant pressure cycles of 6-ton class excavation.

Direct Fitment: Precision-manufactured to match original Hitachi mounting flanges and splined drive shafts, ensuring a 100% "bolt-on" replacement that requires no modification to the machine's housing.
