This is a high-performance hydraulic pump designed to provide the necessary flow and pressure for the main hydraulic system in Volvo articulated haulers. It is the heart of the hydraulic system, powering functions like steering, braking, and implement operation. Constructed from robust materials, this pump ensures reliable and efficient operation under heavy loads, unlike a worn pump which would exhibit reduced flow and increased internal leakage. Operators may notice slow or unresponsive hydraulic functions, whining noises from the pump, or overheating of the hydraulic fluid when this component 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 initial symptom of a failing hydraulic pump is a noticeable decrease in the speed and power of hydraulic functions. If ignored, the pump's internal wear will worsen, leading to increased fluid temperatures and potential cavitation noises. The ultimate consequence is a complete loss of hydraulic power, rendering the equipment inoperable and potentially causing damage to other hydraulic components.
Ensure the hydraulic reservoir is completely drained and flushed before installing the new pump to remove any debris. Prime the new pump according to the manufacturer's instructions before initial startup to prevent dry running.
Inspect and replace the hydraulic filter and check the condition of all hydraulic hoses and fittings during pump replacement.
