G1313-89701, Agilent Transport Assembly's x, z and Theta Motor Assembly (pulley)

The Transport Assembly Theta Motor is a repair component for the sample transport mechanism of Agilent G1329A and G1329B autosamplers. Autosampler motion relies on coordinated positioning to bring sample containers and the injection mechanism into correct alignment. The theta motor supports the rotational axis within that transport assembly; abnormal positioning behavior may require inspection of motor operation, drive transmission and related sensors. This component is intended for equipment maintenance, not for direct contact with chromatographic samples. Before replacing any transport motor, shut down the instrument safely and check the correct service documentation for access, cable routing and motor alignment. Avoid forcing mechanical movement or changing unrelated axis settings during diagnosis. Once repaired, carry out the instrument's initialization and movement tests, followed by an injection sequence to confirm repeatability. Compatibility is limited to the identified autosampler platforms, and this theta motor must not be confused with separate X- or Z-axis components.
