OEM Cummins CCEC NTA855 Diesel Engine Fan Hub 3655291 | Tonkee®

Material: The fan hub is typically constructed from high-quality materials like cast iron or aluminum alloy, ensuring durability and resistance to corrosion.

Mounting: It is designed to be mounted on the front of the engine and is connected to the engine's crankshaft.

Function: The primary function of the fan hub is to control the operation of the cooling fan. It allows the fan to engage and disengage as needed to maintain the engine's optimal operating temperature.

Engagement Mechanism: The fan hub features an engagement mechanism that allows it to be disengaged when the engine does not require additional cooling. This feature helps improve fuel efficiency by reducing the load on the engine when cooling is unnecessary.

Bearing: The fan hub contains high-quality bearings that enable smooth and reliable operation. These bearings are designed to withstand the rigors of engine operation and provide long service life.

Compatibility: The 3655291 fan hub is specifically designed for use with the NTA855 series diesel engine.

It is crucial to ensure compatibility when replacing or servicing the fan hub to maintain engine performance.

Maintenance: Regular inspection and maintenance of the fan hub are essential to ensure its proper functioning. This includes lubrication of bearings and checking for signs of wear and tear.

Temperature Control: The fan hub responds to changes in engine temperature, engaging the cooling fan when the engine reaches a certain temperature threshold. This prevents the engine from overheating and helps maintain its efficiency.

Belt-Driven: In many installations, the cooling fan is belt-driven, with the fan hub serving as a critical component in transferring power from the engine's crankshaft to the fan.

OEM Quality: The 3655291 fan hub is manufactured to Cummins' strict quality standards, ensuring that it meets or exceeds original equipment manufacturer (OEM) specifications. This guarantees reliable performance and compatibility with Cummins NTA855 engines.
