Cummins®

The Cummins 191491 V Belt is a component designed for use in commercial trucks. It serves a vital role in the operation of these vehicles by facilitating the transfer of power between various engine components. Understanding its function and importance can help in maintaining the efficiency and reliability of truck operations.

Basic Concepts of V Belts

V belts are a type of belt drive used in mechanical systems to transmit power between two or more pulleys. They are characterized by their V-shaped cross-section, which allows them to fit snugly into matching grooves on the pulleys. This design enhances grip and reduces slippage, making V belts effective for power transmission in various applications. The V-shaped profile also increases the surface area in contact with the pulley, improving the belt’s ability to transmit power efficiently ¹.

Purpose of the 191491 V Belt

The Cummins 191491 V Belt is specifically designed to connect and drive various components within a truck’s engine system. It typically links the engine to accessories such as the alternator, water pump, and air conditioning compressor. By doing so, it ensures these components receive the necessary power to function correctly, supporting the overall operation of the vehicle.

Key Features

This Cummins part is constructed from high-quality materials that offer durability and resistance to wear. Its design includes features that enhance performance, such as a robust core and a durable outer layer. These elements contribute to the belt’s longevity and reliability under the demanding conditions of commercial truck operation.

Benefits of Using the 191491 V Belt
