Procedure

    1. SUBTASK 72-38-11-020-051 Remove the Inlet Cone Fairing

    1. Refer to Figure and Figure.

    2. NOTE

      The two remaining bolts will hold the inlet cone fairing.

      Hold the inlet cone and remove four of the six sysmmetrical bolts which attach the inlet cone fairing to the inlet cone and the front blade retaining ring.

    3. Loosen the two remaining bolts which attach the inlet cone fairing.

    4. Use IAE 1J12125 Sliding hammer 1 off to release the inlet cone fairing from the flange of the front blade retaining ring.

    5. Remove the two remaining bolts.

    6. Remove the inlet cone fairing from the inlet cone and the front blade retaining ring.

    2. SUBTASK 72-38-11-020-052 Remove the Inlet Cone and the Trim Balance Weights (if installed)

    1. Refer to Figure, Figure and Figure.

      2. Do the subsequent steps to make sure the installation of the trim balance weights in the same bolt holes during installation if they are installed.

      1. NOTE

        Make sure that each correlation number of the trim balance weights to the front blade retaining ring is aligned.

        Give correlation numbers, with the CoMat 06-069 MARKER, to the trim balance weights to show their initial position to the front blade retaining ring.

      2. Put the numbers that agree with those in step (1) on the outer flange surface of the front blade retaining ring.

    3. NOTE

      Hold the inlet cone while you loosen the bolts. This prevents rotation of the fan rotor.
      Use identification tags to keep the trim balance weights removed and their correlation number.

      Remove the 18 bolts, the washers (if installed) and the trim balance weights (if installed) which attach the inlet cone to the front blade retaining ring.

    4. NOTE

      Hold the inlet cone before it is released.

      Use IAE 1J12020 Puller leer 1 off or IAE 1J12121 Puller leer 1 off to release the inlet cone from the flange of the front blade retaining ring.

    3. SUBTASK 72-38-11-220-051 Examine the Interfaces

    1. Examine the inlet cone (non-modular) at interface A and the LP compressor (fan) module front face at interface A-31. Refer to TASK 72-00-00-200-000 (INSPECTION/CHECK-000).
