Test stand apparatus and method for testing a rebuilt torque converter

Abstract

A test stand for pressure testing rebuilt torque converters includes a retainer frame assembly for supportably receiving the torque converter and a plug assembly for sealing and pressurizing the interior of the torque converter. The retainer frame assembly includes a cup for receiving the pilot hub of the torque converter and a locking bar with safety latches for retaining the plug assembly in the central aperture of the torque converter when the interior of the torque converter is pressurized. The retainer frame assembly is mounted on a vertical support stand and can pivot 90 degrees with respect to the support stand to change the central axis of the torque converter from vertical to horizontal. The retainer frame assembly is also capable of rotating 360 degrees with respect to the support stand. The torque converter may be installed in the retainer frame assembly when the retainer frame is oriented with the cup facing upwardly so that the retainer frame assembly supports the torque converter. After the plug assembly and locking bar have been engaged, the interior of the torque converter may be pressurized and the retainer frame assembly pivoted until the central axis of the torque converter is horizontal. The torque converter and retainer frame assembly may be rotated while bubble-producing fluid is applied to the circumferential seam of the torque converter.
