Basic Parameters & Introduction
"This high-precision hydraulic main pump assembly (double plunger pump) has a core original part number of 9227923. As the power core of the entire hydraulic system, this assembly is specially designed for Hitachi's new generation of efficient excavators, perfectly matching the ZX120-6 and ZAX120-6 (120-6 series) small and medium-sized core models. The product is designed with high precision in fluid mechanics based on first principles, ensuring absolute certainty of high-pressure and high flow output, and perfectly supporting multi action composite working conditions. The physical dimensions of the product packaging are approximately 580mm × 340mm × 360mm, with an overall net weight of approximately 85kg. The original factory standard position is seamlessly connected, and the performance parameters are perfectly matched.

Maintenance Tips
"Daily inspection (every 10 hours): Before starting work, it is mandatory to check the sealing of the main pump shaft seal and high-pressure pipeline joints to eliminate any trace leakage hazards.

First running in period (50 hours of operation): After the new pump is installed and put into operation for 50 hours, the return oil filter element and the pilot high-precision filter element must be forcibly replaced to thoroughly filter out the initial trace debris.

Regular mandatory replacement (every 500/2000 hours): replace the entire hydraulic filter element of the vehicle every 500 hours; The oil tank must be thoroughly cleaned and the original factory standard anti-wear hydraulic oil replaced every 2000 hours (or up to 1 year). If in a high load crushing condition, the cycle needs to be forcibly shortened by 50%."

Installation Tips
"Extreme cleaning: Noise reduction and dust removal treatment are required for the unpacking and installation environment. All hydraulic pipeline joints must be thoroughly cleaned with specialized cleaning agents before connecting to a new pump, and foreign objects are strictly prohibited from entering the pump body.

Forced oil filling (core pit avoidance): After installation and before starting the engine, clean hydraulic oil must be filled from the air release/oil injection port on the top of the main pump. It is strictly prohibited to start dry grinding, otherwise the internal rotating components will undergo irreversible physical erosion within 3 seconds of ignition.

Low pressure transition: After the first ignition, the system must idle at low pressure for 10-15 minutes for automatic exhaust and thermodynamic adaptation. The working load can only be gradually applied after the oil temperature is normal."
