Introduction

The Cummins 4365970 V-Ribbed Belt is a critical component for commercial trucks, essential for the efficient operation of these vehicles. This belt is a key part of the engine’s accessory drive system, transferring power to components such as the alternator, water pump, and power steering pump. Its proper function is vital for the reliable performance of these systems, contributing to the overall efficiency and longevity of the truck.

Basic Concepts of V-Ribbed Belts

V-Ribbed Belts, characterized by their trapezoidal cross-section, offer a larger contact area with pulleys compared to flat belts, enhancing power transmission efficiency and reducing slippage ¹. Constructed from multiple layers of synthetic materials, including polyester cords for strength and a rubber compound for flexibility, V-Ribbed Belts are designed to withstand the demanding conditions of commercial truck engines. Unlike timing belts, which synchronize engine components, V-Ribbed Belts drive accessories not directly involved in the combustion process.
