This is a hydraulic gear pump, the heart of the hydraulic system responsible for generating the flow and pressure needed to operate various machine functions. It is built to Volvo's exacting standards for durability and consistent output, outperforming worn pumps that exhibit reduced flow and increased noise. Operators may observe sluggish hydraulic functions, overheating of the hydraulic oil, or unusual noises emanating from the pump when it 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.
Early signs of a failing gear pump include a noticeable increase in hydraulic system noise and slower response from hydraulic functions. If left unaddressed, the pump will lose its ability to generate adequate flow and pressure, leading to significantly reduced machine productivity and potential overheating of the hydraulic oil. Continued operation risks damage to other hydraulic components due to inadequate lubrication and pressure.
Thoroughly clean the hydraulic tank and lines before installation, and always prime the new pump with clean hydraulic oil before connecting it to the system. Ensure the pump shaft is correctly aligned with the drive coupling to prevent premature wear.
Replace the main hydraulic filter and inspect the hydraulic oil for contamination when replacing the gear pump.
