This is a high-pressure hydraulic pump crucial for powering the machine's functions in Volvo wheel loaders. It converts mechanical energy into hydraulic flow, delivering the necessary fluid power for lifting, steering, and auxiliary systems. A failing pump will result in a noticeable loss of hydraulic power, slow or erratic operation of functions, and potentially whining or grinding noises from the pump housing.

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 pump is a noticeable decrease in the speed and power of hydraulic functions. If left unaddressed, this will progress to erratic or completely non-functional hydraulics, potentially leaving the equipment immobile and unable to perform its tasks. Continued operation with a failing pump can also lead to contamination of the entire hydraulic system.
Ensure the hydraulic reservoir is completely drained and flushed before installing the new pump to remove any debris. Do not overtighten the mounting bolts, as this can distort the pump housing.
Always replace the hydraulic filter and inspect the hydraulic fluid for contamination when replacing the hydraulic pump.
