FAQ

Q: Is this radiator fan a direct fit for my 6BT generator engine?
A: Yes, Part No. 4913961 is designed as a direct replacement for the 6BT series. However, we recommend verifying the fan diameter, blade pitch, and mounting bolt pattern against your existing fan to ensure a perfect fit, as minor variations exist across different generator set configurations.

Q: What maintenance is required for this fan after installation?
A: Regular inspection of the fan blades for cracks, deformation, or debris build-up is recommended. Ensure the fan clutch (if applicable) is functioning correctly and that the radiator shroud is properly aligned. Typically, a visual check during routine oil changes is sufficient.

Q: Can this fan be used on a KTA38 engine in a high-ambient-temperature environment?
A: Yes, this fan is engineered for heavy-duty cooling demands. For extreme conditions (above 50°C), we advise confirming that your radiator core and fan drive system are also adequately rated. If you have specific cooling requirements, please contact our technical team for application guidance.
