Procedure

    1. SUBTASK 72-32-72-220-088 Examine the Valve Pin Hole Bush

    1. Refer to Figure.

      2. Measure and record the shoulder thickness of the bush BF1 and BF2.

      1. Use external micrometer.

      3. Calculate and record dimensions VF1 and VF2.

        1. The calculating formula are as follows.

        1. VF1 = 0.3100in. (7.875 mm) - BF1

        2. VF2 = 0.3100in. (7.875 mm) - BF2

    2. SUBTASK 72-32-72-320-051 Machine the Worn Pin Hole(s) on the Valve

    1. Refer to Figure, Figure, Figure and Figure.

      2. Set a rotary table on to the horizontal boring machine.

      3. Put machining fixture on to the boring machine.

      4. Set machining fixture by surface B and C given in the figure.

    5. Install and clamp the valve into the machining fixture.

      6. Machine the worn pin hole and face of the valve to the dimensions given in the figure.

    7. Remove the valve from the machining fixture.

    3. SUBTASK 72-32-72-220-089 Examine the Machined Valve

    1. Refer to Figure, Figure and Figure.

      2. Measure the dimensions of the pin hole and thickness on the valve.

        1. Use dial bore gage.

    4. SUBTASK 72-32-72-230-060 Examine the Machined Pin Hole and Face of the Valve for Cracks

      1. Do a penetrant crack test on the machined area.

        1. No cracks are permitted.

        1. Refer to the SPM TASK 70-23-02-230-501.

    5. SUBTASK 72-32-72-380-057 Apply the Chromate Conversion Coating to the Valve

      1. Apply the chromate conversion coating to the machined pin hole and face of the valve.

      1. Refer to the SPM TASK 70-38-02-300-503, SUBTASK 70-38-02-300-002.

    6. SUBTASK 72-32-72-350-059 Install the Bush(es) (01-160 and/or 01-170) to the Valve

    1. Refer to Figure and Figure

      2. Heat the valve at 320 to 392 deg F (160 to 200 deg C) for 30 minutes.

      1. Use an Oven.

      3. Install the bush(es) to the valve.

        1. Use Standard workshop equipment with heat protective grooves.

        1. Use 5A1799 (01-160) bush and/or 5A1800 (01-170) bush.

    7. SUBTASK 72-32-72-220-090 Examine the Bush(es) for Location

    1. Refer to Figure and Figure.

      2. Visually examine the bush(es).

      1. Make sure the bush(es) are pushed fully into positions.

      3. Dimensionally inspect the bush(es) for location.

    8. SUBTASK 72-32-72-350-060 Identify the Repair

      1. Make a mark VRS1360 adjacent to the part number.

        1. Refer to the SPM TASK 70-09-00-400-501, SUBTASK 70-09-00-400-001.

      2. Apply the chromate conversion coating to the marked letter.

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