Q: Why is my D375A-6 engine overheating despite the fan spinning?
A: The fan motor 708-7H-00680 may be experiencing internal bypass leakage. Even if it rotates, it may not reach the required RPM to move enough air. Testing the hydraulic pressure at the motor inlet is the first step.
Q: Is there an oil leak coming from the fan motor shaft?
A: This usually indicates a failure of the main shaft seal. While seal kits are available, if the shaft itself is worn, a complete replacement of the 708-7H-00680 assembly is recommended to prevent hydraulic system contamination.
Q: Why Choose This Fan Motor?
A: It features an OEM-standard tri-metal structure and is trusted by repair shops and equipment fleets worldwide for its longevity in harsh mining conditions.
