Abstract
A method of inserting an injector in a test head includes inserting the injector in a puck; aligning the puck beneath the test head; engaging a bottom of the puck with a floating cone assembly; raising the puck upwards towards the test head; and inserting a top portion of the injector into the test head. The floating locator cone assembly includes a floating locator cone mount; a ball thrust bearing assembly inserted in the floating locator cone mount; and a floating locator cone inserted in the floating locator cone mount on top of the ball thrust bearing. Use of the floating locator cone assembly allows the puck to center itself thereby allowing the injector to be properly aligned upon insertion in the test head. Proper alignment of the injector reduces false leak test readings and the consequent rejection of good injectors.
