This is a high-pressure hydraulic pump, a core component of the hydraulic system in Volvo excavators, responsible for generating the flow and pressure needed to operate various functions. It is engineered to meet stringent OEM performance and durability standards, ensuring consistent power delivery unlike a worn pump that exhibits reduced output. Operators may experience slow or weak hydraulic movements, loss of lifting capacity, or unusual noises from the hydraulic system when this pump 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.
The first noticeable symptom of a failing hydraulic pump is a general sluggishness or lack of power in all hydraulic functions. As the internal wear progresses, the pump's output will decrease, leading to slower boom, stick, and bucket movements, and a reduced ability to lift heavy loads. Continued operation with a worn pump can lead to overheating of the hydraulic fluid and potential damage to other system components.
Thoroughly clean the area around the pump mounting before removal to prevent dirt from entering the hydraulic system. Ensure the pump shaft is properly aligned with the drive coupling before tightening mounting bolts to avoid premature shaft or coupling failure.
Flush the hydraulic system and replace the main hydraulic filter; inspect all hydraulic hoses and seals for wear or leaks.
