A25D Fan Motor for Volvo A25D 25-ton Articulated Dump Truck spare parts

Short Description:

The Volvo A25D fan motor is an original hydraulic drive cooling fan motor exclusively matched for Volvo A25D 25-ton articulated dump truck. As the core power component of the equipment’s intelligent heat dissipation system, it replaces traditional engine direct drive structure and adopts independent hydraulic drive mode. It precisely drives the cooling fan to operate, providing stable heat dissipation airflow for engine water tank, hydraulic oil radiator and intercooler. Adapted to frequent start-stop, heavy-load climbing and dusty and high-temperature operation scenarios of mining and earthwork transportation, this fan motor features constant temperature adaptive speed regulation, stable rotation output, low failure rate and strong anti-pollution capability, ensuring the whole vehicle maintains optimal working temperature and avoids overheating failure during long-term continuous heavy-load transportation.

description

The genuine Volvo A25D hydraulic fan motor adopts high-efficiency fixed-displacement hydraulic motor structure, professionally calibrated for Volvo A25D vehicle hydraulic system and temperature control logic. Equipped with precision internal rotor pair, high-pressure wear-resistant bearing assembly and integrated high-temperature sealing structure, it realizes stepless adaptive speed adjustment following system temperature changes. When the engine and hydraulic system are at low temperature, the motor runs at low speed to reduce power loss and fuel consumption; under high-temperature and heavy-load working conditions, it automatically increases speed to enhance heat dissipation efficiency, effectively solving common overheating problems during long-distance heavy-load transportation and summer high-temperature operation. The core moving parts undergo precision finishing and surface strengthening treatment, with low rotation resistance and strong fatigue resistance. The high-rigidity metal shell resists on-site vibration, dust erosion and hydraulic impact. All finished motors pass factory hydraulic pressure test, speed calibration and high and low temperature cycle durability test, featuring stable operation and long service life.

maintenance & replacement tips

Regularly check the motor mounting bolts, oil inlet and outlet joints and sealing surfaces to eliminate oil leakage risks caused by long-term vehicle bumping and vibration.
Clean fan blades and radiator dust regularly to avoid poor heat dissipation caused by blockage, which leads to long-term high-load operation of the fan motor and accelerated wear.
Replace hydraulic oil and filter elements on schedule to prevent impurity particles from scratching internal rotor pairs and bearings, resulting in unstable speed and insufficient heat dissipation.
Regularly test the operating speed and hydraulic working pressure of the fan motor to ensure it runs within the rated range and matches the vehicle temperature control system.
Avoid long-term overload operation and frequent impact of foreign objects on fan blades to prevent motor shaft deformation and internal component damage.
Timely replace genuine A25D fan motor when faults such as weak heat dissipation, unstable speed, oil leakage and system high temperature occur to restore vehicle heat dissipation performance.
