Cummins®

The Cummins 2874280 Fan Pulley is a component designed for use in commercial trucks, playing a role in the engine cooling system by facilitating the operation of the cooling fan. This ensures that the engine maintains an optimal operating temperature, which is important for efficient performance and longevity ¹.

Basic Concepts of a Fan Pulley

A fan pulley is a mechanical device that connects the engine’s crankshaft to the cooling fan. It operates by transferring rotational force from the engine to the fan, allowing the fan to draw air through the radiator. This process helps dissipate heat from the engine coolant, maintaining the engine within its optimal temperature range. The fan pulley works in conjunction with the fan clutch and radiator to regulate engine temperature effectively ².

Purpose of the Cummins 2874280 Fan Pulley

This Cummins part serves to drive the cooling fan in commercial trucks. By ensuring the fan operates at the correct speed in relation to engine RPM, it plays a role in maintaining optimal engine temperature. This, in turn, contributes to efficient engine performance and helps prevent overheating, which can lead to engine damage ³.
