Procedure

    1. SUBTASK 72-32-71-350-084 Remove the Defective Spherical Bearing from the Arm Assembly

    1. Refer to Figure and Figure.

    2. Examine and identify defective spherical bearing.

      3. Press out defective spherical bearing.

    2. SUBTASK 72-32-71-230-083 Examine the Arm Assembly

    3. SUBTASK 72-32-71-220-149 Examine the Arm Assembly

    1. Refer to Figure.

      2. Dimensionally examine the hole of the arm.

      1. Make sure that it is correct diameter.

    4. SUBTASK 72-32-71-350-085 Install the New Spherical Bearing

    1. Refer to Figure and Figure.

      2. Clean the new spherical bearing and the hole of the arm.

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

      3. Install the bearing.

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

      4. Swage the arm to fix the bearing.

        1. Apply swaging force of 8000 lbf.

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

      5. Do proof-test.

        1. Apply axial load of 300 lbf to the inner race.

        2. Invert the arm and re-apply load.

        3. If it has shifted, re-swage or replace bearing with higher swaging load.

      6. Examine the ball for free movement in the race.

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

        1. If the torque is not in these limits, replace the bearing with lower swaging load.

        2. Fig/item 02-100, Limit 5.10 lbfin (58 kgfmm) max.

        3. Fig/item 02-455, Limit 15.0 lbfin (173 kgfmm) max.

    5. SUBTASK 72-32-71-220-150 Examine the Spherical Bearing Seating

    1. Refer to Figure.

      2. Visually examine the spherical bearing seating.

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