Procedure

    1. SUBTASK 72-60-25-350-085 Remove the Threaded Inserts

    1. Refer to Fig. 72-60-25-990-042.

      2. Remove the inserts.

      1. Refer to Repair, VRS5048, TASK 72-60-25-300-003 (REPAIR-003).

    2. SUBTASK 72-60-25-320-083 Machine the Mating Surface of the Housing

    1. Refer to Fig. 72-60-25-990-042.

      2. Machine the mating surface.

      1. The preplating dimension must be between 1.0157 and 1.0185 in. (25.800 and 25.870 mm) in relation to surface 'B', index 2, after the removal of the damage.

    3. SUBTASK 72-60-25-230-059 Examine the Housing

      1. Do the fluorescent penetrant inspection for cracks.

      1. Refer to the SPM TASK 70-23-01-230-501.

      2. No cracks are permitted.

    4. SUBTASK 72-60-25-330-071 Nickel Plate the Seal Housing Mating Surface

      1. Mask the areas of the housing not to be plated.

      2. Do the nickel plating.

      1. Refer to the SPM TASK 70-33-08-300-503.

      2. Plate to a sufficient thickness to permit the machining to the last dimension.

    3. Remove the mask.

      4. Clean and dry the housing.

      1. Flush with cold water.

      2. Flush with hot water.

      3. Dry with air blast.

    5. SUBTASK 72-60-25-370-066 De-embrittle the Housing

      1. Put the housing into an oven at 241 to 260 deg F (116 to 127 deg C) for 60 to 90 minutes.

      1. Do this process as soon as possible in less than 4 hours after the plating.

    6. SUBTASK 72-60-25-220-139 Examine the Housing

      1. Do the visual inspection of the plating for finish, cracks and adhesion.

      1. Plating must have a constant color.

      2. No circumferential cracks are permitted.

      3. No rough and blistering are permitted.

    7. SUBTASK 72-60-25-320-084 Machine the Seal Housing Mating Surface

    1. Refer to Fig. 72-60-25-990-042.

      2. Machine the mating surface.

      1. The last dimension must be between 1.0197 and 1.0276 in. (25.900 and 26.100 mm).

      2. The parallelism of the surface must be in 0.002 in. (0.05 mm) FIR in relation to surface 'A', index 1.

      3. Chamfer, where necessary.

    8. SUBTASK 72-60-25-220-140 Examine the Nickel Plated Area

      1. Do the visual inspection of the plated area for cracks and adhesion.

      1. Use a magnifying glass.

      2. The natural network cracks, emphasized by grinding, is permitted.

      2. Measure the thickness of the plating.

      1. Do not accept thickness less than 0.0006 in. (0.015 mm) after the last machining.

    9. SUBTASK 72-60-25-350-086 Install the Threaded Inserts

    1. Refer to Fig. 72-60-25-990-042.

      2. Install the inserts.

      1. Refer to VRS5048 TASK 72-60-25-300-003 (REPAIR-003 Page-901).

    10. SUBTASK 72-60-25-350-087 Record the Repair

      1. Vibroengrave 'VRS5050' adjacent to the part number.

      1. Remove the metal lifted by marking.
