This is a Hydraulic Pump, a core component of the excavator's hydraulic system that generates the flow and pressure needed for all machine functions. Manufactured to stringent standards, it provides consistent performance, unlike a worn pump which can cause erratic or weak operation. Operators may notice slow or unresponsive boom, stick, or bucket movements, or a general loss of hydraulic power.
Always verify with serial number before ordering.

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.
Initial symptoms of a failing hydraulic pump include sluggish or inconsistent hydraulic functions, such as slow bucket curl or boom extension. If ignored, the pump's output will continue to degrade, leading to a significant loss of machine productivity. The risk is that critical hydraulic functions may cease to operate, immobilizing the equipment.
Thoroughly clean the area around the pump mounting before removal to prevent dirt ingress into the hydraulic system. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature wear.
Replace the hydraulic filter and inspect the hydraulic fluid for metal particles or signs of degradation.
