Safety Requirements
NONEProcedure
Refer to Figure.
Inspect and identify the defective spherical bearing.
Refer to Figure DETAIL E.
Use an Arbor Press and IAE 3J12745 Swaging tool 1 off.
Press out the defective spherical bearing.
Refer to the SPM TASK 70-35-03-300-501.
Scratches are permitted but remove the burrs.
Check damage in the bore.
SUBTASK 72-32-71-350-061 Remove the Defective Spherical Bearing from the Link Assembly
Refer to the SPM TASK 70-23-05-230-501.
Make sure there are no cracks in the hole.
Fluorescent penetrant examine the spherical bearing hole.
SUBTASK 72-32-71-230-063 Examine the Link Assembly for Cracks
Refer to Figure.
Ensure the correct diameter.
Dimensionally inspect the hole of the link.
SUBTASK 72-32-71-220-090 Inspect the Link Assembly
Use clean dry air blast or CoMat 02-099 LINT-FREE CLOTH.
Clean the new spherical bearing and the hole of the link.
Position the bearing race slightly below the surface of link.
Use an Arbor Press and IAE 3J12745 Swaging tool 1 off.
Install the bearing.
Apply a swaging force to the 45 degrees circumferential position from the existing swage point up to the depth of the swage.
Invert the link and re-apply the swaging force.
Use an Arbor Press and IAE 3J12745 Swaging tool 1 off.
Swage the link to fix the bearing.
Refer to Figure DETAIL G.
If movement is not free, install a screw, a nut and washers and measure torque required to rotate the ball.
Inspect the ball for free movement in the race.
Refer to Figure.
NOTE
If the torque exceeds the limits as follows:Fig/Item 01-240, torque limit 2.6 lbfin (30 kgmm).Fig/Item 01-440, torque limit 2.6 lbfin (30 kgmm).Replace the bearing using lower staking load.Use IAE 2J12622 Depth gage 1 off.
Measure the depth of the swage.
SUBTASK 72-32-71-350-062 Install the New Spherical Bearing
Refer to Figure.
Race of bearing must be located just below the arm face.
Visually examine the spherical bearing seating.
SUBTASK 72-32-71-220-091 Examine the Spherical Bearing Seating
Refer to the SPM TASK 70-38-02-300-503.
Apply the chromate conversion coating to swage area.
SUBTASK 72-32-71-380-056 Apply Surface Protection to the Link Assembly
