Narrative:
Prior to the installation of the r-hand main landing gear I noticed damage to the aft pintle pin spherical bearing. It appears a used bearing was accidentally installed on this main landing gear leg. The bearing appears badly damaged from wear and also was covered in sealant. Upon removal of the sealant I discovered the damage to the bearings inner and outer surfaces.
