Cummins®

The Cummins 146654 Fan Pulley is a component designed for use in heavy-duty trucks. Its purpose is to facilitate the operation of the engine cooling system by transferring power from the engine to the cooling fan. This part is significant in maintaining optimal engine temperature, which is vital for the efficient and reliable performance of heavy-duty trucks ¹.

Basic Concepts of a Fan Pulley

A fan pulley is a mechanical component that plays a role in the engine cooling system by driving the cooling fan. It is connected to the engine via a belt and works in conjunction with the fan clutch and radiator to regulate engine temperature. The fan pulley’s rotation drives the fan, which pulls air through the radiator to cool the engine coolant. This interaction ensures that the engine operates within its optimal temperature range, preventing overheating and potential damage ².

Purpose of the 146654 Fan Pulley

This Cummins part is designed to transfer power from the engine to the cooling fan efficiently. This transfer is crucial for maintaining the engine’s temperature under various operating conditions. By ensuring that the cooling fan operates at the correct speed, the fan pulley helps to regulate the flow of air through the radiator, contributing to the overall cooling efficiency of the engine.

Key Features

This part features a robust design that includes high-quality materials to enhance its performance and durability.
