The indexing section consists of three basic parts: Spline Mandrel, Spline Sleeve, and J-Pin, The function of the indexing section is to sequentially open and close the testing valve as the spline Mandrel (attached to the drill stem) is moved up and down. These motions may be repeated as many times as desired, each complete cycle opening and closing the testing valve. The indexing slot is in the Spline Mandrel and is shown in Figure Ⅱ. The Spline Mandrel is splined to the body of the tool and cannot rotate—it can move only in an axial direction, i.e., up or down. The J-Pin is securely fastened to the Spline Sleeve and rides in the index slot. The Spline Sleeve rotates freely through an 180°arc , but cannot move axially. We can see that as the Spline Mandrel moves up and down, the J-Pin follows the path of the index slot freely due to the rotation of the Spline Sleeve.
