Procedure

    1. SUBTASK 72-32-72-350-054 Remove the Damaged Seal from the Valve Ring Assembly

    1. CAUTION

      WHEN YOU REMOVE DAMAGED SEAL, DO NOT CAUSE DAMAGE TO THE PARENT MATERIAL.

      Refer to Figure.

    2. Examine the seal.

      3. Remove damaged seal and all remaining compound.

      1. Use cutter knife or scraper.

    2. SUBTASK 72-32-72-380-053 Apply the Surface Protection to the Valve Ring Assembly

      1. Apply chromate conversion coating to the repair surfaces, if necessary.

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

    3. SUBTASK 72-32-72-360-053 Prepare the Mating Surfaces for the Cold Curing Silicone Rubber Compound

    1. Refer to Figure.

      2. Cold liquid degrease the mating surfaces of the valve ring assembly and the seal.

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

      3. Hand clean the mating surface of the seal only.

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

    4. NOTE

      A water-break test is not necessary.

      Do Step again.

    4. SUBTASK 72-32-72-360-056 Apply and Cure the Cold Curing Silicone Rubber Compound

    1. CAUTION

      YOU MUST 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

      BONDING MUST BE DONE IMMEDIATELY AFTER THE SURFACE PREPARATION.

      Refer to Figure.

      NOTE

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

      NOTE

      If the parts are not used immediately, after the primer is applied, they must be kept in polythene bags; but for no longer than 24 hours.

      2. Apply a thin layer of primer only to the prepared mating surface of the valve ring assembly. Dry in air for 30 minutes.

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

      3. CAUTION

        APPLY THE COLD CURING SILICONE RUBBER COMPOUND TO A MINIMUM THICKNESS OF 0.021 IN. (0.53 MM) IN ORDER TO PREVENT SEAL PEELING.

        NOTE

        Only CoMat 08-013B COLD CURING SILICONE COMPOUND or CoMat 08-013F COLD CURING SILICONE COMPOUND can be used as listed in the Overhaul Process and Consumable Index.

        Apply the cold curing silicone rubber compound to the mating surfaces of the valve ring assembly and the seal.

      1. Use a spatula and CoMat 08-013B COLD CURING SILICONE COMPOUND or CoMat 08-013F COLD CURING SILICONE COMPOUND. A minimum thickness of the compound must be 0.021 in. (0.53 mm).

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

      4. Install the seal to the valve ring assembly within 3 minutes after the compound applied.

      2. Apply sufficient pressure to ensure good contact, and to make the seal surface smooth, and to form a witness of compound at all edges.

      3. Make sure the compound can be seen around the sealed surface.

      5. NOTE

        The part can be touched after 12 hours.

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

      1. Do not apply a load during this time.

    5. SUBTASK 72-32-72-220-073 Examine the Repaired Area of the Valve Ring Assembly

    1. Refer to Figure.

    2. Dimensionally examine the position of the repaired seal.

    3. Visually examine the protrusion of compound.

    6. Figure: Replace the Seal
