Procedure

    1. SUBTASK 72-32-71-350-063 Remove the Defective Spherical Bearing from the Power Arm Assembly

      1. Inspect and identify defective spherical bearing.

      1. Refer to Figure.

      2. Press out defective spherical bearing.

        1. Refer to Figure DETAIL E.

      3. Check damage in bore.

        1. Scratches are permitted by remove the burrs.

        2. Refer to the SPM TASK 70-35-03-300-501.

    2. SUBTASK 72-32-71-230-064 Examine the Power Arm Assembly for Cracks

      1. Fluorescent penetrant examine the spherical bearing hole.

        1. Make sure there is no cracks in the hole.

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

    3. SUBTASK 72-32-71-220-092 Inspect the Power Arm Assembly

      1. Dimensionally inspect the hole of the power arm.

        1. Ensure the correct diamter.

        1. Refer to Figure.

    4. SUBTASK 72-32-71-350-064 Install the New Spherical Bearing

      1. Clean the new spherical bearing and the hole of the power arm.

      1. Use clean dry air blast or CoMat 02-099 LINT-FREE CLOTH.

      2. Install the bearing.

        1. Use an arbor press and IAE IAE 3J12745 Swaging tool 1 off.

        1. Position bearing race slightly below the surface of arm.

        2. Refer to Figure and Figure DETAIL E.

      3. Swage the arm to fix the bearing.

        1. Apply swaging force to the 45 degrees circumferential position from the existing swage point up to the depth of the swage.

        2. Invert the arm and re-apply swaging force.

        3. Refer to Figure and Figure DETAIL F.

      4. Inspect the ball for free movement in the race.

        1. NOTE

          If the torque exceeds the limits as follows:
          Fig/Item 01-340, torque limit 6.0 lbfin (69 kgmm).
          Fig/Item 01-370, torque limit 2.6 lbfin (30 kgmm).
          Replace the bearing using lower staking load.

          If movement is not free, install screw, nut and washers and measure torque required to rotate the ball.

        1. Refer to Figure DETAIL G.

    5. SUBTASK 72-32-71-220-093 Examine the Spherical Bearing Seating

      1. Visually examine the spherical bearing seating.

        1. Race of bearing must be located just below the arm face.

        1. Refer to Figure.
