Description

This premium heavy-duty raw-edge cogged power transmission V-belt (13AV profile / 13mm top width, 2037mm outer length) is manufactured to original equipment standards using fiber-reinforced polychloroprene synthetic rubber, deep molded cogs, and high-modulus polyester tension cords. Designed for high-stress heavy commercial truck and bus auxiliary drive systems (large-capacity alternators, water pumps, cooling fans, and air conditioning compressor setups), the raw-edge cogged construction provides outstanding flex fatigue resistance, enhanced airflow for cooler operating temperatures, and superior grip around multi-accessory pulley configurations. Replacing a stretched, cracked, glazed, or slipping drive belt restores full electrical charging generation and cooling efficiency, eliminates screeching under heavy commercial load, and prevents unexpected auxiliary drive failure.

Compatible Vehicles & Applications

Mercedes-Benz Heavy Commercial Trucks & Bus Chassis (OM352 / OM366 / OM401 / OM421 Diesel Engine Auxiliary & Fan Drives)

Mercedes-Benz Unimog Utility & Heavy-Duty Off-Road Platforms (Engine Accessory & Water Pump Drives)

Universal Heavy Commercial Trucks, Bus Fleets & Industrial Machinery (13AV / 13mm Cogged Profile x 2037mm La Drives)

Application Note: Specifically engineered for Mercedes-Benz commercial truck and bus platforms utilizing long-span auxiliary drive layouts requiring a heavy-duty 13AV (13mm top width) raw-edge cogged V-belt profile. Important Fitment Note: Clean all pulley grooves thoroughly with a wire brush to remove rust, scale, oil, and rubber glaze prior to fitting. Inspect pulleys for uneven groove wear or misalignment. Do not force or lever the belt over pulley flanges with screwdrivers as this fractures internal tension cords; slacken the adjustment bracket or tensioner pulley completely, fit the belt, and adjust tension to factory deflection specifications (approx. 10–12 mm flex on the longest span under moderate thumb pressure). Re-check belt tension after 50 km or 5 hours of heavy operation.
