ELBOW 1143825 - Caterpillar

Note: Weigh three new air filter elements with the same part number. Take the average of the three air filter elements. This measurement is your standard weight for a new air filter element. (1) The air filter element is returned to the system that uses bar codes for a second weighing. Position the cleaned air filter element on the digital scale. Weigh the cleaned air filter element. If the cleaned air filter element is within 0.27 0.18 kg (0.6 0.4 lb) of the standard weight for the new air filter element, the air filter element passes. If the actual weight of the cleaned air filter element exceeds 0.27 0.18 kg (0.6 0.4 lb), the air filter element fails. The following chart shows when an air filter element passes or an air filter element fails.Note: Discard all failed air filter elements.Note: The target weight is calculated by adding 0.27 0.18 kg (0.6 0.4 lb) to the standard weight.
