This hydraulic pump is a critical component responsible for generating the flow and pressure required to operate the hydraulic systems on Volvo articulated haulers and wheel loaders. It converts mechanical energy from the engine into hydraulic power, enabling functions like lifting, steering, and braking. A worn hydraulic pump may produce reduced flow, leading to slow or weak hydraulic functions, or generate excessive noise.

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, such as lifting or steering. If the issue progresses, the pump may start to make unusual noises, and the hydraulic system could overheat due to internal leakage. Continued operation risks significant damage to other hydraulic components and potential operational downtime.
Thoroughly flush the hydraulic system and replace the hydraulic filter before installing the new pump to prevent contamination. Ensure the pump shaft is properly aligned with the drive coupling to avoid premature wear.
Always replace the hydraulic filter and inspect the hydraulic fluid for contamination when servicing or replacing the hydraulic pump.
