This is a main hydraulic pump, a critical component responsible for generating the high-pressure fluid flow required to operate the excavator's primary functions. Manufactured to meet rigorous performance standards, it ensures consistent power delivery, unlike a worn pump that may exhibit reduced flow and pressure. Operators will notice a significant loss of power, slow or erratic operation of boom, stick, and bucket functions, and potentially increased hydraulic system temperatures when this pump is failing.

Flush hydraulic lines before fitting new components. Use only manufacturer-specified hydraulic fluid. Check O-rings and backup rings for correct orientation. Bleed air from system after installation.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first indication of a failing main hydraulic pump is a noticeable decrease in the speed and power of the excavator's main functions. If left unaddressed, the pump's output will continue to diminish, leading to sluggish operation and potential overheating of the hydraulic system. Ultimately, the machine may become unable to perform essential tasks, significantly impacting productivity.
Ensure the hydraulic system is thoroughly flushed and new filters are installed before fitting the new pump to prevent contamination. Never run the new pump dry; prime it with clean hydraulic oil before initial startup.
Replace the main hydraulic filter and inspect the hydraulic oil for contamination when installing a new main hydraulic pump.
