The ConCar AVX13 V-belt with an outer length (La) of 1,600 mm is designed for drives where this exact profile and length are specified. Its 13 × 10 mm cross-section transmits the rotary motion via suitable pulleys and can drive auxiliary components depending on the vehicle or machine design.
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. Depending on the drive system, this type of belt can be used to operate an alternator, cooling fan, water pump, or compressor. The manufacturer's specifications for the specific belt drive always take precedence.
The additional reference lengths Lw = 1,582 mm and Li = 1,537 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 1600 La with the labeling of your previous belt and the manufacturer's documentation. Pay attention to whether it uses La, Lw, or Li.
Store the belt in its natural shape in a dry, dark place. Avoid pressure points, sharp bends, and contact with aggressive chemicals. A ConCar V-belt is supplied in the profile and length specified above.
