This Charging Pump Assembly is essential for supplying the main hydraulic pump with adequate low-pressure fluid, ensuring consistent system performance and preventing cavitation. Manufactured to Volvo's high standards, it provides reliable flow and pressure, unlike a worn pump that can starve the main system. Operators may notice a loss of main hydraulic power, overheating of the hydraulic oil, or unusual noises from the main pump when this charging pump begins to fail.
Always verify with serial number before ordering.

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 charging pump will initially lead to a noticeable reduction in the overall hydraulic system's responsiveness and power. If ignored, the main hydraulic pump may begin to cavitate, producing audible whining noises and causing rapid wear on its internal components. The ultimate consequence is potential damage to the main hydraulic pump, leading to costly repairs and significant equipment downtime.
Ensure the suction line and inlet port are completely free of any obstructions or debris before connecting the new pump. Do not operate the pump dry; prime it with hydraulic fluid if possible before initial startup.
Inspect the hydraulic tank for cleanliness and check the suction strainer for blockages; replace the main hydraulic filter.
