The 6PK in the name refers to the specific type of serpentine belt that features six ribs. This designation is important because it indicates both the belt's width and the number of grooves designed for maximum grip and efficiency. The 202140 typically represents the length of the belt in millimeters. Serpentine belts, including the 6PK 202140, are used in vehicles to drive multiple peripheral devices from a single crankshaft pulley. These devices often include the alternator, power steering pump, water pump, air conditioning compressor, and sometimes the fan.

A poly V belt, also known as a serpentine belt, is characterized by its multiple longitudinal ribs that provide increased surface contact and improved grip compared to traditional flat belts. The “135J6” designation denotes the specific dimensions and specifications of the belt. In this case, “135” refers to the belt’s length, while “J6” indicates the width and configuration. The poly V belt is designed to fit into a pulley system and is often used to drive multiple accessories in engines, including alternators, power steering pumps, and air conditioning compressors.

V-belts are a crucial component in various mechanical systems and are widely used in automotive, industrial, and agricultural applications. They transfer power between rotating shafts, enabling machines to perform efficiently. Understanding V-belt standard sizes is essential for selecting the right belt for your application, ensuring optimal performance and longevity.

Despite their many benefits, ribbed belts are not without challenges. Over time, they can become damaged due to factors such as misalignment, excessive tension, or contamination from oil or coolant leaks. Regular inspections are essential to ensure that the ribbed belt remains in good condition. Signs of wear include fraying, cracking, or glazing on the surface of the belt, which indicate that a replacement may be necessary.

3. Reduced Noise and Vibration The increased surface contact of V-ribbed belts results in smoother operation, which minimizes noise and vibration compared to flat belt systems.

3. Replacement Schedule Most manufacturers recommend replacing serpentine belts every 60,000 to 100,000 miles. However, it’s wise to consult your Cummins engine manual for specific recommendations, as these can vary based on the model and type of engine.

Серпантинный ремень – это длинный гибкий ремень, который замыкали на несколько шкивов в двигателе автомобиля. Он обычно изготавливается из резины, в reinforced with fibers, чтобы обеспечить дополнительную прочность и долговечность. Серпантинный ремень также известен как агрегатный или приводной ремень, так как он соединяет различные механизмы в автомобиле, такие как генератор, насос гидроусилителя рулевого управления, компрессор кондиционера и другие системы.

3. Misalignment Pulleys that are misaligned can affect the belt’s path, causing uneven tension and increasing the likelihood of slipping.
