This is a Hydraulic Pump designed to supply pressurized fluid to the various hydraulic circuits of Volvo excavators. Manufactured to precise tolerances, it ensures efficient power transfer and reliable operation, unlike a worn pump that may exhibit reduced flow or pressure. Operators may experience sluggish hydraulic functions, a noticeable loss of power during operation, or unusual noises emanating from the hydraulic pump when this unit 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.
Initial symptoms often include a general decrease in the speed and power of hydraulic functions. If ignored, the excavator may struggle to lift heavy loads, and the hydraulic system might overheat due to the pump's inefficiency. Continued operation with a failing pump risks damage to other critical hydraulic components.
Ensure the hydraulic system is completely flushed of any debris or old fluid before installing the new pump to prevent contamination. Always prime the new pump with clean hydraulic fluid before initial startup.
Replace the hydraulic filter element(s) and inspect all hydraulic hoses and fittings for leaks or wear when replacing the hydraulic pump.
