This hydraulic pump is a vital component for the main hydraulic system of Volvo articulated haulers, responsible for generating the flow and pressure needed for steering, braking, and implement operation. It converts mechanical input into hydraulic power, ensuring the machine can perform its intended functions efficiently. Operators may notice a gradual decrease in steering responsiveness, slower braking action, or reduced power to the dump bed as indicators of a worn or failing pump.

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 initial symptom of a failing hydraulic pump is a noticeable reduction in the speed and power of hydraulic functions, such as steering or raising the dump bed. If the issue is not addressed, the pump may eventually fail to provide sufficient hydraulic pressure, leading to a loss of steering control or the inability to operate the dump bed. This poses a significant operational risk and can lead to extended downtime.
Ensure the hydraulic system is completely free of air after installation by following the manufacturer's priming procedure. Avoid running the pump dry at any point during installation or initial startup, as this can cause immediate damage.
Inspect the hydraulic fluid for contamination and check the condition of the hydraulic filter when replacing the hydraulic pump.
