Procedure

    1. SUBTASK 72-32-19-320-055 Grind the Damaged Surface of the Hydraulic Seal Assembly

    1. Refer to Figure.

      2. Install the fixture into the grinding machine.

      3. Install the hydraulic seal assembly on to the fixture and set to turn correctly.

      2. Make sure that datum A and B are set to turn correctly.

      4. Grind the rear surface of the differential seal to the dimensions given in the figure.

      1. Grind only the minimum quantity of material to remove damage.

    2. SUBTASK 72-32-19-220-076 Examine the Machined Surface of the Hydraulic Seal Assembly

    1. Refer to Figure.

      2. Measure and record the dimension of the differential seal given in the figure.

      3. Examine the machined surface for the remaining pits.

        1. All pits, if damage depth is not more than 0.004 in. (0.10 mm).

        1. Accept.

        2. More than in (1).

        1. Reject.

    3. SUBTASK 72-32-19-230-054 Examine the Hydraulic Seal Assembly for Cracks

      1. Do a fluorescent penetrant inspection on the machined surface.

      1. No cracks are permitted.

      3. Use FPI equipment.

      4. Refer to the SPM TASK 70-23-05-230-501.

    4. SUBTASK 72-32-19-340-051 Plasma Spray the Hydraulic Seal Assembly

    1. Refer to Figure.

      2. Clean the hydraulic seal assembly.

      1. Refer to the SPM TASK 70-11-03-300-503.

      3. Apply masking tape to the area which is not to be given plasma spray.

      4. Install the hydraulic seal assembly on to the fixture.

      5. Abrasive blast the rear face of the differential seal.

      1. Refer to the SPM TASK 70-34-01-340-501.

      6. Renew masking if necessary.

      7. Plasma spray the rear face of the differential seal.

      1. Apply the plasma spray to a sufficient thickness which will permit the final machining of 1.4626 to 1.4665in. (37.15 to 37.25 mm).

      2. The maximum thickness of the plasma spray must be 0.010 in. (0.25 mm).

      3. Refer to the SPM TASK 70-34-01-340-501.

      8. Remove masking tape and any over spray coat.

      1. Use non-metallic hand scraper.

    5. SUBTASK 72-32-19-320-056 Grind the Rear Face of the Differential Seal

    1. Refer to Figure.

      2. Install the fixture into the grinding machine.

      3. Install the hydraulic seal assembly on to the fixture and set to turn correctly.

      2. Make sure that datum A and B are set to turn correctly.

      4. Grind the rear face of the differential seal to the dimensions given in the figure.

      1. The minimum plasma spray coating thickness is 0.003 in. (0.08 mm).

      2. Refer to the SPM TASK 70-34-01-340-501.

    6. SUBTASK 72-32-19-220-077 Examine the Rear Face of the Differential Seal

    1. Refer to Figure.

      2. Visually examine the coated area for chips, cracks, lifted material and coating that is not attached to the base metal.

      2. Refer to the SPM TASK 70-34-01-340-501.

      3. Dimensionally examine the rear face.

    7. SUBTASK 72-32-19-350-052 Identify the Repair

      1. Write VRS1233 adjacent to the part number.

      1. Mark a permanent mark by the procedure given in the SPM TASK 70-09-00-400-501.
