The ConCar AVX13 V-belt with an outer length (La) of 1,168 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.
If the vehicle or machine documentation specifies the outer length, compare it directly to La = 1,168 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 purchasing a new belt, compare the markings on your existing belt with the specifications provided by the vehicle or machine manufacturer. Also, check that the pulleys are clean, aligned, and free of sharp edges. Adjust the tension according to the manufacturer's instructions: too little tension can cause slippage, while too much tension puts unnecessary strain on the bearings and belt.
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 1.168 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.
