This is a hydraulic fan motor that powers the cooling fan for the engine and hydraulic systems on Volvo excavators. It converts hydraulic pressure into rotational force, ensuring consistent airflow for optimal temperature management. A worn or failing motor will result in slow or erratic fan speeds, leading to overheating and reduced operational efficiency.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
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 fan motor is typically a reduction in fan speed or inconsistent fan operation, leading to elevated engine or hydraulic oil temperatures. If this condition persists, the fan may cease to rotate, causing critical components to overheat. This can lead to significant operational interruptions and costly repairs to the cooling system.
Ensure the hydraulic system is thoroughly cleaned and filled with fresh, clean hydraulic fluid to prevent contamination of the new motor. Avoid overtightening mounting bolts, which can warp the motor casing.
Inspect hydraulic lines, fittings, and the hydraulic fluid for contamination or leaks before installing the new fan motor.
