This gear pump is a critical component of the excavator's hydraulic system, responsible for generating the necessary flow and pressure to operate various functions. Manufactured to meet rigorous OEM standards, it offers reliable performance and durability, unlike a worn pump that may produce insufficient flow or excessive heat. Operators may experience a general loss of hydraulic power, slow implement speeds, or a whining noise from the pump when this unit begins to fail.

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.
A failing gear pump will initially present as a noticeable reduction in the speed and power of hydraulic functions. If ignored, the pump's output will continue to decrease, leading to sluggish operation and potential overheating of the hydraulic system. Continued operation with a worn gear pump risks damage to other hydraulic components due to insufficient flow and pressure.
Ensure the hydraulic system is completely clean before installing the new pump, as even small particles can cause premature wear. Do not rotate the pump shaft by hand before installation if it is sealed; allow the hydraulic system pressure to prime it.
Inspect the hydraulic fluid for contamination and replace the hydraulic filter when installing a new gear pump.
