Hydraulic Fan Motor 505-5179 505-5180 for E336GC E345GC 336 355 Excavator

This hydraulic fan motor is a core cooling component for the E336GC and E345GC excavators. Driven by hydraulic oil, it rotates the cooling fan and can automatically adjust speed according to engine temperature. It also supports a reverse fan function, effectively dissipating heat from the radiator and hydraulic system. Manufactured with high-strength materials and precision processing, it offers direct replacement installation and stable output torque, making it well suited to heavy-duty construction conditions.

• 1.Internal seal aging leading to hydraulic oil leakage
• 2.Abnormal noise and jamming during operation
• 3.Insufficient rotating speed, causing machine overheating
• 4.Spline shaft wear resulting in power transmission failure
• 5.Housing cracks caused by impact and high temperature

• 1.Confirm the part number and machine serial number before ordering
• 2.Check port size, spline specification, and rotation direction
• 3.Request strict pressure and performance testing before shipment
• 4.Package with shockproof protection to avoid damage in transit
• 5.Provide warranty coverage for quality problems
