This is a hydraulic pump for the wheel loader's drive system, responsible for providing the necessary hydraulic power to propel the machine. It is manufactured to meet Volvo's stringent quality and performance specifications, ensuring reliable power transfer unlike a worn pump with internal leaks. Operators may notice a loss of drive power, slow or jerky transmission response, or difficulty climbing inclines when this pump is failing.

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 hydraulic drive pump is typically a reduction in the loader's travel speed or power, especially when under load. This can escalate to intermittent loss of drive, transmission shuddering, or the inability to climb moderate grades. Continued operation risks significant damage to the transmission and drive components due to insufficient or erratic hydraulic power.
Thoroughly flush the hydraulic system and replace the transmission filter before installing the new pump to prevent contamination. Ensure the pump shaft is properly lubricated before insertion to avoid binding.
Replace the transmission filter and inspect the hydraulic fluid for debris or signs of wear when replacing the hydraulic drive pump.
