This ConCar AVX13 V-belt is designed for a drive system with a length of 1,325 mm and a cross-section of 13 × 10 mm. The belt connects driving and driven pulleys and is suitable – depending on the specific system – for driving vehicle auxiliary components.
The open-flanked, toothed underside enhances flexibility as it 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. The profile is designed for compact belt drives where the corresponding AVX cross-section is specified. Depending on the design, the belt can be used to drive fans, pumps, or other auxiliary components.
The additional reference lengths Lw = 1,307 mm and Li = 1,262 mm simplify selection when the old belt marking uses a different length specification. 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.
For replacement, both the profile and length are important. Check the grooves of the discs for wear and ensure correct alignment during installation. The required tension can be found in the drive's instructions; a general setting is not suitable for every system.
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 1.325 La with the labeling of the previous belt and the manufacturer's documentation. Pay attention to whether it uses La, Lw, or Li.
Until installation, the belt should be stored without tension, in a dry place, and protected from direct heat and sunlight. Do not kink or twist it. A ConCar V-belt in the profile and length specified above is supplied.
