Procedure

    1. SUBTASK 72-44-30-350-080 Remove the Liner Segments in Rows 1, 2 and 5 from the Combustion Chamber Inner Liner

    1. Refer to Figure.

      2. Loosen the liner segments in rows 3 and 4 if necessary. Remove and discard the nuts.

      1. You can use a pneumatic or electric nut splitter to remove the nuts instead of a breakaway torque measurement.

    3. Remove the nuts and the liner segments in rows 1, 2 and 5. Discard the nuts.

    2. SUBTASK 72-44-30-350-081-001 Size to Restore the Front Outside Seal Diameter of the Combustion Chamber Inner Liner

    1. Refer to Figure.

      2. Use sizing clusters in a sizer/shrinker to form a rear ring to the diameter.

      1. Resize the diameter to 16.619 to 16.631 in. (422.12 to 422.43 mm).

    3. SUBTASK 72-44-30-350-082-002 Roll to Restore the Front Outside Diameter Seal Diameter of the Combustion Chamber Inner Liner

    1. Refer to Figure.

      2. Use a rolling tool in a vertical turret lathe to roll the diameter of the inner liner.

      1. Roll the diameter to 16.619 to 16.631 in. (422.12 to 422.43 mm).

    4. SUBTASK 72-44-30-230-054 Examine the Shell and the Weld after Sizing or Rolling

      1. Locally fluorescent penetrant inspect the shell and the weld after sizing is completed.

    5. SUBTASK 72-44-30-220-085 Examine the Front Outside Seal Diameter of the Combustion Chamber Inner Liner

      1. Examine the front outside seal diameter for the coating after sizing or rolling.

    6. SUBTASK 72-44-30-350-083 Install the Liner Segments

    1. Refer to Figure and Figure.

      2. CAUTION

        DO NOT USE COMAT 10-049 MOLYBDENUM DISULFIDE TO LUBRICATE THE NUT THREADS. MOLYBDENUM DISULFIDE CAN CAUSE CORROSION.

        CAUTION

        DO NOT USE ENGINE OIL AND COATING CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER ON THE SAME STUDS.

        CAUTION

        IT IS REQUIRED TO USE COATING CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER ON ROW 1 LINER SEGMENTS AFTER FINAL TORQUE THE NUTS. DO NOT USE COATING CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER ON ALL THE STUD THREADS DURING INSTALLATION.

        CAUTION

        COATING CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER IS OPTIONAL ON OTHER LINER SEGMENTS (ROWS 2 THRU 5). HOWEVER, DO NOT USE COATING CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER IF ENGINE OIL WAS ALREADY APPLIED ON THE STUD THREADS.

        CAUTION

        IF COATING CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER WAS USED IN LINER SEGMENTS, LIGHTLY USE A STAINLESS STEEL WIRE BRUSH TO REMOVE LOOSE DEBRIS BEFORE NEW COATING.

        Install the replacement liner segments from rear-most row to front most row with washers and new nuts. Replace all loosened or removed nuts with new nuts.

      1. Install oval-shaped washers with dimple facing to the liner shell and seated in slot.

        If engine oil is preferred on Rows 2 thru 5 liner segments, apply engine oil on the stud threads. Do not use engine oil on Row 1 liner segment stud threads.

        Install the nuts with IAE 3P16238 Angle box wrench (angle box wrench) 1 off.

        Torque the segment's center stud first followed by the two adjacent studs then the segment's two outer-most studs. Tighten nuts down on the stud between 40 to 50 lbfin (4.519 to 5.649 Nm) of torque and make sure that the washer is not free to move. Back the nut off one-half turn, then use IAE 3P16239 Ratchet wrench (ratchet wrench) 1 off to torque the nut to 25 to 35 lbfin (2.824 to 3.954 Nm).

        Apply CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER coating compound on the threaded studs of the Row 1 liner segments, use a small artists brush. Full coverage is necessary, but there is no thickness limit. Refer to Figure for coating application.

        If engine oil was not used on liner segments Row 2 thru 5, apply CoMat 07-175 COATING COMPOUND - ALUMINUM, INORGANIC BINDER on the threaded studs using a small artist's brush. Complete coverage is necessary but there is no thickness requirement. Refer to Figure as a reference for coating application.
