Buy HITACHI ZX120 ZX130 HYDRAULIC PUMP SHAFT DRIVE | Tonkee®

The hydraulic pump shaft drive in the Hitachi ZX120 and ZX130 is a key component that connects the engine to the hydraulic pump.

Its primary function is to transfer mechanical energy from the engine to the hydraulic pump, which, in turn, converts this energy into hydraulic pressure to operate the various hydraulic cylinders and motors on the excavator.
Material and Construction: Typically, the hydraulic pump shaft drive is constructed from high-quality, heat-treated steel to withstand the significant mechanical stress and torque generated during operation. This ensures the longevity and reliability of the component, which is vital in demanding construction environments.
Compatibility: The hydraulic pump shaft drive for the Hitachi ZX120 and ZX130 is designed to be a precise fit for these specific excavator models. It is essential to ensure compatibility when replacing or maintaining this component to guarantee optimal performance and prevent potential issues down the line.

Functionality: The hydraulic pump shaft drive consists of a splined shaft that connects to the engine's crankshaft on one end and a coupling on the other end that attaches to the hydraulic pump.

As the engine runs, it spins the shaft, which, in turn, drives the hydraulic pump. This rotational motion is converted into hydraulic pressure, which powers the various hydraulic functions of the excavator, such as the boom, arm, and bucket movements.
Maintenance and Care: Proper maintenance of the hydraulic pump shaft drive is crucial to ensure the excavator's continued performance and longevity. Regular inspections, lubrication, and monitoring for signs of wear or damage are essential. If any issues are detected, prompt replacement or repairs should be carried out to avoid costly downtime and potential damage to other hydraulic system components.
Performance Considerations: The performance of the hydraulic pump shaft drive directly impacts the excavator's overall efficiency and productivity. A well-maintained and correctly functioning drive shaft ensures that the hydraulic system operates smoothly, providing precise control over the excavator's movements and functions.
Reliability and Durability: Hitachi is known for producing robust and reliable construction equipment, and the hydraulic pump shaft drive is no exception. It is built to withstand the rigors of heavy-duty excavation work, ensuring that the excavator can operate consistently in challenging conditions.
