## Discrepancy

FOUND BEARING, ASSUMED TO BE PN 5542308-7, INSTALLED IN NLG ASSEMBLY, PN 6642000-74.  THE STRUT WAS DISASSEMBLED FOR A RESEAL IAW OPERATOR'S REQUEST.  DURING DISASSEMBLY OF THE STRUT ASSEMBLY THE BEARING WAS DISCOVERED TO BE THE WRONG ONE.  REPLACED BEARING WITH PN 6642308-3 WHICH IS CALLED OUT IN THE EFFECTIVITY OF THE INSTALLED STRUT.  THE WRONG BEARING DID NOT FULLY SEAT ONTO THE PISTON ASSEMBLY WHICH OFFSET THE SET SCREWS & MARRED THE PISTON ASSEMBLY.  THAT NECESSITATED REPLACEMENT OF THE PISTON ASSEMBLY AS WELL.  NO OTHER DEFECTS REGARDING THE PERFORMANCE OF THE NOSE GEAR WERE EITHER OBSERVED OR REPORTED.
