Article description\r\n\n\r\n\nThrough different measurement and production processes in the V-belt manufacturers, different lengths are produced across the entire manufacturer.\nHowever, these differences do not affect the functionality of the belts.\nVarious paramaters are used to determine the lengths.\nExternal length (Length external, short Le), internal length (length internal, short Li), and echoes are distinguished.\nThe length of the cable describes the length measurement to approx. 3/4 height of the belt according to DIN 2215.\nIn addition, the belt tension specified by the vehicle manufacturer must also be taken into account for reliable length measurement since this is also an important factor during the production process.\nBecause of these different measuring methods, different V-belt sizes can come from different manufacturers on one and the same vehicle.\nPlease refer to our vehicle instructions.\n \nDayco designs, develops and produces complete power transmission sys.
