This hydraulic axial piston pump is the heart of the machine's main hydraulic system, generating high-pressure fluid flow to power functions like boom, stick, bucket, and drive motors. It is manufactured to stringent standards to ensure consistent pressure and flow rates, unlike a worn pump that loses efficiency and produces less power. Operators will observe sluggish hydraulic functions, a noticeable decrease in lifting or digging force, and potentially increased system noise when this pump begins to fail.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of a failing hydraulic pump is often a noticeable reduction in the speed and power of hydraulic functions. As the problem progresses, the machine may struggle to lift loads or move attachments effectively, and the hydraulic system may overheat. Continued operation with a worn pump can lead to complete loss of hydraulic power, significantly impacting the machine's operational capability.
Thoroughly flush the hydraulic system and replace all filters before installing a new pump to prevent contamination from entering the new component. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature wear.
Inspect all hydraulic hoses, seals, and cylinders for leaks or damage, and clean or replace hydraulic system filters.
