Safety Requirements

CAUTION

IF IT IS NECESSARY TO APPLY PLASMA SPRAY BY REPAIR-005 (VRS3227) AND REPAIR-006 (VRS3229) BECAUSE THE FRONT AND REAR OUTER DIAMETERS ARE WORN OUT AT THE SAME TIME, APPLY THE PLASMA SPRAY ON THE FRONT OUTER DIAMETER (REPAIR-005) FIRST AND THEN APPLY THE PLASMA SPRAY ON THE REAR OUTER DIAMETER (REPAIR-006) NEXT.
IF YOU MUST DO REPAIR-005 (VRS3227) AND REPAIR-006 (VRS3229) AT THE SAME TIME, YOU MUST REMOVE THE SHOULDER PINS IN PARAGRAPH 4.

Procedure

    1. SUBTASK 72-45-27-350-058 Remove all the Shoulder Pins

      1. If you must do Repair-005 (VRS3227) and Repair-006 (VRS3229) at the same time, remove the shoulder pins.

      1. Refer to Repair, VRS3228 TASK 72-45-27-300-007 (REPAIR-007).

    2. SUBTASK 72-45-27-320-051 Machine the Front Outer Diameter before Plasma Spray

    1. Refer to Figure and Figure.

      2. Do a machine or grind operation to remove the damage or wear and all the coating from the front outer diameter face.

      1. Remove the minimum quantity of parent material necessary to do the repair.

      3. Clean the part.

      4. If you removed the damage and coating by grind operation, do a fluorescent penetrant inspection of the part.

      5. Do a dimensional inspection of the repair area.

      1. Refer to Figure. Make sure you removed all the coating.

        NOTE

        If the measured axial dimensions in a free condition are not satisfactory, a held condition is permitted. All dimensions apply when Surface E is flat by 0.002 in. (0.05 mm) and Diameter N maintain a clearance envelope of 28.542 in. (724.97 mm) in a free or held condition. In a held condition, hold the air seal only on Surfaces E and F and Diameter N. In a free condition Surface E is flat by 0.010 in. (0.254 mm) and Diameter D is 28.550 to 28.626 in. (725.17 to 727.10 mm) in diameter.

    3. SUBTASK 72-45-27-340-051 Plasma Spray the Front Outer Diameter

    1. Refer to Figure.

      2. Plasma spray the front outer diameter.

      1. Apply the plasma spray to a sufficient thickness which will permit the final machining of the dimensions given in the figure.

        No overpsray is permitted.

        Do the procedure given in the SPM TASK 70-34-00-340-501.

    4. SUBTASK 72-45-27-320-052 Finish Machine the Front Outer Diameter after Plasma Spray

    1. Refer to Figure.

      2. Set-up and finish machine the front outer diameter.

      1. The finished plasma spray thickness must be between 0.003 and 0.015 in. (0.08 and 0.38 mm).

    3. NOTE

      If the measured axial dimensions in a free condition are not satisfactory, a held condition is permitted. All dimensions apply when Surface E is flat by 0.002 in. (0.05 mm) and Diameter N maintain a clearance envelope of 28.542 in. (724.97 mm) in a free or held condition. In a held condition, hold the air seal only on Surfaces E and F and Diameter N. In a free condition Surface E is flat by 0.010 in. (0.25 mm) and Diameter D is 28.550 to 28.626 in. (725.17 to 727.10 mm) in diameter.

    5. SUBTASK 72-45-27-220-061 Examine the Repair

    1. Refer to Figure and Figure.

    2. If you do this repair in conjunction with VRS3229 on the same part, do a dimensional inspection to make sure datum B is in part print limits.

    6. SUBTASK 72-45-27-350-052 Identify the Repair

    1. Refer to Figure.

      2. Make a mark VRS3227 adjacent to the part number.

      1. Make a permanent mark by the procedures given in the SPM TASK 70-09-00-400-501. Use the vibration peen method.

    7. SUBTASK 72-45-27-350-063 If Removed the Shoulder Pins, Replace all the Shoulder Pins

      1. Install the shoulder pins.

      1. Refer to Repair, VRS3228 TASK 72-45-27-300-007 (REPAIR-007).
