Introduction

The Cummins 3289675 V-Ribbed Belt is a component designed for use in commercial trucks. It serves a role in the engine system by transferring power from the engine to various components such as the alternator, water pump, and air conditioning compressor. This belt ensures these components operate efficiently, contributing to the overall performance and reliability of the truck ³.

Basic Concepts of V-Ribbed Belts

V-Ribbed Belts are characterized by their trapezoidal cross-section, which allows them to fit snugly into corresponding grooves on pulleys. This design enhances grip and reduces slippage, ensuring efficient power transmission. Unlike flat belts, V-Ribbed Belts can transmit more power and are less prone to misalignment. They are also more compact, allowing for more components to be driven by a single belt ¹.

Role of the 3289675 V-Ribbed Belt in Truck Operation

This Cummins part plays a role in the operation of a truck by driving multiple engine components. It connects the crankshaft to the alternator, water pump, and air conditioning compressor, among others. This setup ensures that electrical power is generated, the engine remains cool, and the air conditioning system functions properly. The efficient operation of these components contributes to the truck’s overall performance and reliability ².

Key Features of the 3289675 V-Ribbed Belt

The 3289675 V-Ribbed Belt is constructed from high-quality materials that enhance its durability and performance. Its design includes multiple ribs that increase the contact surface area with pulleys, improving power transmission efficiency. The belt is also engineered to withstand the high temperatures and dynamic loads typical in commercial truck engines. These features contribute to its longevity and reliability in demanding applications ⁴.

Benefits of Using the 3289675 V-Ribbed Belt

Using this Cummins part offers several advantages. Its efficient power transmission capabilities contribute to improved engine performance. The belt’s durable construction reduces the frequency of replacements and maintenance, leading to lower overall costs.
