This main hydraulic pump is essential for the operation of Volvo excavators, providing the high-pressure fluid flow required for all primary functions like boom, stick, and bucket movement. Built to meet strict OEM performance and durability standards, it ensures consistent hydraulic power, unlike a worn pump that suffers from reduced output and efficiency. Operators will typically notice a significant loss of power and speed in all hydraulic operations 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 indication of a failing main hydraulic pump is a general sluggishness and loss of power across all hydraulic functions, such as slower boom or bucket movements. As the pump wears, internal leakage increases, leading to reduced system pressure, overheating, and potentially a complete loss of hydraulic power. Continued operation risks severe damage to the pump itself and other hydraulic components due to insufficient lubrication and pressure.
Always prime the new pump with clean hydraulic fluid before connecting it to the system to prevent internal damage from dry operation. Ensure the hydraulic system is completely flushed to remove any debris that could quickly damage the new pump.
Replace the main hydraulic filter and inspect the hydraulic fluid for metal particles, which indicate pump wear.
