Procedure

    1. SUBTASK 72-31-11-350-075 Remove the Damaged Seal and Bumper from the Annulus Filler Assembly

    1. Refer to Figure.

    2. Examine and identify the damaged seals and pad bumper.

      3. Remove the damaged seals and bumper. Do not cause damage to the parent material. Remove all compound that remains.

      1. Use a cutter, a knife or a scraper.

    2. SUBTASK 72-31-11-360-060 Prepare the Mating Surface for the Cold Curing Silicone Rubber Compound

    1. Refer to: Figure

      2. Remove the grease from the mating surfaces of the annulus filler, the seals and the pad bumper.

      1. Refer to the SPM TASK 70-11-26-300-503.

    4. Do step A. again.

    3. SUBTASK 72-31-11-350-076 Apply the Surface Protection to the Annulus Filler Assembly

    1. Refer to: Figure

      2. Apply chromate conversion coating to the repair surfaces as necessary.

      1. Refer to the SPM TASK 70-38-02-300-503.

    4. SUBTASK 72-31-11-360-061 Apply and Cure the Cold Curing Silicone Rubber Compound

    1. CAUTION

      DO NOT EAT OR SMOKE AT LOCATIONS WHERE THESE MATERIALS ARE USED.

      CAUTION

      AFTER PREPARATION, THE MATING SURFACES MUST BE FULLY CLEANED AND MUST NOT BE TOUCHED BY HAND TO PREVENT CONTAMINATION.

      CAUTION

      DO NOT APPLY THE PRIMER TO THE MATING SURFACES OF THE SEALS AND BUMPER BECAUSE THE SILICONE RUBBER WILL BE WEAKENED IN BOND STRENGTH IF YOU APPLY THE PRIMER.

      CAUTION

      APPLY THE PRIMER IN LESS THAN EIGHT HOURS AFTER ANODIZING (CHROMATE CONVERSION COATING).

      Refer to Figure.

      2. NOTE

        The primer must be applied immediately after the mating surfaces are prepared. It is cured at room temperature by the moisture in the air.

        Apply a very thin layer of primer only to the prepared mating surface of the annulus filler. Dry at room temperature for a minimum of 30 minutes.

      3. Apply the cold curing silicone rubber compound to each of the mating surfaces.

      2. Refer to the SPM TASK 70-36-02-360-501.

      4. Install the seals and the pad bumper to the annulus filler in less than three minutes after the compound is applied.

      1. Apply sufficient pressure to ensure good contact and to form a witness of adhesive at all edges.

      2. Make sure that the compound can be seen around the sealed surfaces.

      3. Refer to the SPM TASK 70-36-02-360-501.

      5. NOTE

        The parts can be handled carefully after two hours at room temperature.

        Cure the compound at 68 deg F (20 deg C) for 48 hours.

      1. Refer to the SPM TASK 70-36-02-360-501.

    6. Deleted.

    7. Deleted.

      8. Vibro-peen VRS1018 adjacent to the part number.

      1. Use a vibro-peen.

      9. Apply chromate conversion coating to the marking letters.

      1. Refer to the SPM TASK 70-38-02-300-503.

    5. SUBTASK 72-31-11-220-089 Examine the Repaired Areas of the Annulus Filler Assembly

    1. Refer to Figure.

    2. Dimensionally inspect the position (dimension E) of the repaired bumper.

      3. Visually examine the seals and bumper.

      1. Make sure that there is not too much adhesive coming out of the bond.

      2. There must be continuity of bond around the seals and bumper.
