This hydraulic pump is the heart of the hydraulic system for Volvo articulated haulers, generating the flow and pressure needed for steering, lifting, and braking functions. It is engineered to precise specifications to ensure reliable operation under demanding conditions. A failing hydraulic pump can manifest as slow or erratic hydraulic movements, loss of steering assist, or complete hydraulic system failure.

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 often a noticeable decrease in the speed and power of hydraulic functions like lifting or steering. If ignored, this degradation will worsen, leading to intermittent loss of hydraulic control and potentially rendering the machine inoperable. The ultimate consequence is the inability to perform essential work tasks, causing significant downtime.
Prime the new pump with clean hydraulic fluid before installation to ensure lubrication and prevent dry running. Avoid cross-threading the hydraulic line fittings when connecting them to the pump.
Thoroughly flush the hydraulic system and inspect the hydraulic fluid reservoir and filters for any debris or metal particles that may indicate internal wear.
