Precision Displacement Control – The Core Actuator for Variable Displacement Hydraulic Pumps.
This genuine Hitachi servo piston is a key component of the pump regulator, functioning as the actuator that adjusts the swash plate angle to control pump displacement. Available in multiple configurations for main pumps (0451030, 4301669, 4428917) and travel motors (9098902), it enables precise flow control for efficient hydraulic system operation.

Precision Engineering for Responsive Control – Built for Continuous Hydraulic Actuation.
Manufactured from high-strength materials with precision-machined surfaces, this servo piston works with the tilting control valve to adjust pump output based on system demands. Its design incorporates a feedback link mechanism that ensures stable displacement control and prevents rattling even under repeated long-term operation. Used extensively across ZX and EX series excavators.

Prevent Pump Inefficiency and Energy Loss – Genuine Hitachi: Ensure Accurate Hydraulic Response.
A worn or faulty servo piston leads to sluggish pump response, inefficient flow control, and increased energy loss—especially during idle or locked conditions. Aftermarket parts often compromise on material quality or dimensional accuracy. This genuine component meets all OEM specifications for material grade and surface finish—ensuring reliable displacement control and maximum hydraulic efficiency.
