<p>A method and apparatus for testing and filling hydraulic assemblies such as a hydraulic clutch control assembly (12) for a motor vehicle. A conduit (36b) is placed in communication with a pressure chamber of the assembly; air is sucked out of the pressure chamber through the conduit while a series of pressure readings are taken in the conduit indicative of the gradually declining pressure within the pressure chamber; the pressure readings are utilized to generate a vacuum signature (114); the vacuum signature is compared to a stored vacuum signature corresponding to an acceptable hydraulic assembly; the hydraulic assembly is accepted or rejected based on the match between the generated vacuum signature and the stored vacuum signature; assuming that the assembly is accepted, liquid is supplied through the conduit to gradually fill the pressure chamber of the assembly while taking a series of pressure readings indicative of the pressure in the chamber during the fill process; the fill pressure readings are utilized to generate a fill signature (116); the fill signature is compared to a stored fill signature corresponding to an acceptable assembly; and the assembly is rejected or accepted based on the correspondence between the generated fill signature and the stored signature.</p> |
