    1. Refer to Figure

      2. Use a hand grinder to remove the seal. Grind through the circumferential weld.

      1. Be careful not to grind into the spark igniter guide.

        The new seal must be 0.575 in. - 0.584 in. (14.605 mm - 14.834 mm) in diameter.

        Replace the seal if it is larger than 0.594 in. (15.088 mm) in diameter.

    2. SUBTASK 72-42-61-310-053 Install the Spark Igniter Seal and the Spark Igniter Retaining Ring

    1. Refer to Figure

    2. Install the seal.

      3. Install the retaining ring and tack weld if necessary.

      1. Make sure there is a 0.030 in. (0.762 mm) maximum gap between the seal and the retaining ring after you tack weld.

        Refer to the SPM TASK 70-31-13-310-501.

      4. Complete the circumferential weld of the retaining ring. Use CoMat 03-197 WELDING FILLER WIRE or equivalent.

      1. Make sure the seal can move freely a minimum of 0.060 in. (1.524 mm) in all directions.

    3. SUBTASK 72-42-61-230-052 Examine the Spark Igniter Retaining Ring Weld

      1. Fluorescent penetrant examine the weld for cracks.

      1. Refer to the SPM TASK 70-23-05-230-501.
