Aftermarket AVX17x1153La Cooling Fan Belt Assembly

This AVX17x1153La cooling fan belt is engineered as a direct replacement for Isuzu OEM part numbers 113671-2080 and I1-13671-2220. It utilizes a raw-edge cogged construction per DIN 7753 / ISO 4184 standards, providing high flexibility and grip on small pulley diameters. The tensile member consists of low-stretch polyester cords embedded in a chloroprene rubber (CR) compound reinforced with transversely oriented fibers. This design ensures high tensile strength, oil resistance, heat resistance, and reduced slippage under heavy-duty operating conditions typical of construction machinery and commercial truck engines. The belt transmits rotational power from the crankshaft to the cooling fan and alternator. It is compatible with Isuzu 4JG1, 4JA1, 4JB1, UM4BD1, and UM4JG1 diesel engines installed in Takeuchi TL140 compact track loaders and Isuzu CXM, CXH, CXZ, EXR, EXZ, FVR series trucks. The outside length (La) is 1153 mm with a top width of 17 mm and a nominal height of 11.5 mm.
