This is a robust hydraulic pump, the primary component responsible for generating the necessary hydraulic flow and pressure to operate the implement and drive systems of Volvo excavators. It is constructed from high-grade materials and manufactured to precise OEM specifications, ensuring reliable performance and extended service life over worn pumps that exhibit reduced output or internal bypass. Operators may notice slow or erratic movement of excavator functions, a drop in lifting capacity, or audible whining sounds from the hydraulic system when this pump fails.

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 sign of a failing hydraulic pump is typically a noticeable decrease in the speed and responsiveness of the excavator's functions. If the issue is not addressed, the pump's performance will continue to degrade, leading to intermittent operation and potential overheating of the hydraulic oil. Continued use with a worn pump can lead to damage to other hydraulic components and loss of operational control.
Before installing the new pump, thoroughly clean the hydraulic system and replace the hydraulic filter to prevent contamination. Ensure the pump shaft is properly aligned with the drive coupling to prevent premature wear on the pump bearings.
When replacing the hydraulic pump, it is critical to inspect the hydraulic fluid for contamination and replace the main hydraulic filter.
