Procedure

    1. SUBTASK 72-50-53-350-099 Remove the Damaged Bushing(s) from the Turbine Exhaust Case Assembly

      1. Remove the damaged bushing and the bushing in the adjacent flange axially in line with it.

      1. Refer to Figure and Figure.

        You can use CoMat 10-077 APPROVED ENGINE OILS to make it easier to remove bushing.

      2. Examine the bushing hole.

      1. Refer to Figure and Figure.

        If the hole is worn, machine the hole for the bushing.

        Refer to Step.

    2. SUBTASK 72-50-53-320-094 Machine the Hole for the Bushing

    1. Refer to Figure.

      2. If the hole is worn, machine the hole to the nearest oversize diameter.

      1. Use the applicable size replacement bushing to get a 0.0010 to 0.0024 in. (0.025 to 0.060 mm) tight fit.

        The minimum distance between the mount lug OD and the bushing bore OD must not be less than 0.600 in. (15.24 mm) after machining.

    3. SUBTASK 72-50-53-230-087 Fluorescent Penetrant Inspect the Turbine Exhaust Case

      1. Fluorescent penetrant inspect the case for cracks.

    4. SUBTASK 72-50-53-350-100 Install New Bushings

      1. Install new bushings.

    5. SUBTASK 72-50-53-320-095 Machine the New Bushings

    1. Put the turbine exhaust case on the table of a jig borer or equivalent.

      2. Line drill the holes.

      1. Use a standard drill.

      3. Line ream the holes with Reamer 1 off to 1.1875 in. to 1.1885 in. (30.163 mm to 30.187 mm).

      1. Refer to Figure and Figure.

    4. Machine the faces of the bushings so the requirements of Figure and Figure are met.
