This is a robust main hydraulic pump, critical for generating the high-pressure flow required by the primary hydraulic systems of Volvo excavators. It is engineered to meet demanding OEM performance and durability standards, providing consistent power output superior to a worn pump. Operators may experience a significant loss of power for digging and lifting functions, slow or jerky hydraulic movements, or a complete lack of hydraulic response 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 indication of a failing main hydraulic pump is a gradual reduction in the speed and power of all hydraulic functions, particularly under load. If ignored, the pump's output will diminish further, leading to erratic operation, overheating of the hydraulic fluid, and potential stalling of the engine due to increased load. Continued operation risks severe damage to the hydraulic system, including the pump itself, cylinders, and valves.
Ensure the hydraulic tank is completely full of the correct fluid type before starting the engine after installation. Never run the pump dry, as this will cause immediate internal damage.
Replace the hydraulic filter element and inspect the hydraulic fluid for any signs of contamination or degradation.
