The ConCar AVX13 is a molded toothed automotive V-belt with an outer length of 1,158 mm and a cross-section of 13 × 10 mm. It transmits the drive power between compatible pulleys and is suitable when the technical specifications of the vehicle or device require this profile and length.
The open-flanked, toothed underside enhances flexibility as the belt rotates over the pulleys. The belt is made of a rubber compound with reinforced polyester/glass fiber tensile members. It is heat- and oil-resistant, as well as antistatic. Typical applications include auxiliary components such as alternators, fans, water pumps, or compressors, provided they are driven by a V-belt of this profile. Which components are actually compatible depends on the design of the specific vehicle or device.
If the vehicle or machine documentation specifies the outer length, compare it directly to La = 1,158 mm. If a different length designation is used, the values Lw and Li will help with the comparison. These three length specifications describe different measurement references for the same belt: La is the outer length, Lw the effective length, and Li the inner length.
Before installation, compare the complete belt designation with the technical documentation. Damaged or heavily worn pulleys can impair the new belt. After installation, the specified tension must be set and checked according to the equipment manufacturer's instructions.
AVX13 is compared to XPA in the ConCar profile assignment. For alternative brands such as Gates, Optibelt, Continental, or Megadyne, the profile, reference length, and approval for the specific drive system must match; the brand name alone does not guarantee a suitable replacement.
Which length is crucial? Compare the specification AVX13 1.158 La with the labeling of the previous belt and the manufacturer's documentation. Pay attention to whether it uses La, Lw, or Li.
Store the belt in a dry, cool place, protected from direct sunlight and without creases. Avoid contact with solvents or other substances that can damage rubber. A ConCar V-belt is supplied in the profile and length specified above.
