Hydraulic Fan Motor 598-7827 505-5180 542-7626 for E395 336 340 345 349 352 Large Mining Excavator

This hydraulic fan motor, available under part numbers 598-7827, 505-5180, and 542-7626, is a cooling hydraulic drive unit specially engineered for the cooling systems of E395, 336, 340, 345, 349, and 352 excavators. It converts hydraulic pressure into rotational power to drive the cooling fan, ensuring effective engine temperature control.

Built with a high-torque piston structure, precise sealing design, wear-resistant alloy materials, and precision machining, this motor delivers stable output performance for heavy-duty mining and construction applications. It is designed for direct replacement installation.

• Internal piston and valve plate wear, causing pressure drop and insufficient fan speed
• Internal seal failure resulting in hydraulic oil leakage
• Abnormal noise and vibration during operation
• Brake or control valve stuck, causing fan speed to go out of control
• Housing cracks caused by overload and high temperature

• Confirm the part number and machine serial number before ordering
• Check spline specification, mounting dimensions, and control type
• Request strict pressure and performance testing before shipment
• Shockproof wooden packaging to prevent transit damage
• Quality warranty covering manufacturing defects
