Procedure

    1. SUBTASK 72-32-75-350-054 Remove the Defective Spherical Bearing from the Rod Assembly

    1. Refer to Figure, Figure and Figure.

    2. Examine and identify the defective spherical bearing.

      3. Push out the defective spherical bearing.

      4. Examine for damage in the bore.

        Scratches are permitted but remove the burrs.

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

    2. SUBTASK 72-32-75-230-055 Examine the Rod Assembly for Cracks

      1. Fluorescent penetrant examine the spherical bearing hole.

      1. Make sure that there are no cracks in the hole.

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

    3. SUBTASK 72-32-75-220-063 Examine the Rod Assembly

    1. Refer to Figure and Figure.

      2. Dimensionally examine the hole of the rod.

      1. Make sure of the correct diameter.

    4. SUBTASK 72-32-75-350-055 Install the New Spherical Bearing

    1. Refer to Figure, Figure and Figure.

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

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

      3. Install the bearing.

      2. Position the bearing race slightly below the surface of the rod.

      4. Swage the rod to fix the bearing.

      1. Use the hydraulic press and the IAE 3J12749 remove and install pusher 1 off.

      2. Apply a swaging force of 8000 lbf.

      3. Turn the rod and re-apply the swaging force.

      5. Do a proof-test.

      1. Use the hydraulic press and the IAE 3J12749 remove and install pusher 1 off.

      2. Apply an axial load of 300 lbf to the inner race.

      3. Turn the rod and re-apply the load.

        If it moves, re-swage or replace the bearing with a higher swaging load.

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

      1. NOTE

        If the torque is out of the limits that follows:
        Fig/Item 01-250 and 01-550, torque limit 5.1 lbfin (58 kgmm) Max.
        Replace the bearing with a lower swaging load.

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

    5. SUBTASK 72-32-75-220-064 Examine the Spherical Bearing Seating

    1. Refer to Figure and Figure.

      2. Visually examine the spherical bearing seating.

      1. The race of bearing is just below the rod face.
