## Discrepancy

TECHS FOUND DIFFICULTY WHILE ATTEMPING TO GREASE NEWLY INSTALLED FLAP CARRIAGE BEARINGS.  BEARINGS WOULD NOT ACCEPT GREASE AS DIRECTED BY THE MM.  A RECALL & INSPECT OF ALL INVENTORIED BEARINGS CARRIED OUT AT SPAR QUALITY DEPARTMENT. BEARINGS IN QUESTION WERE ACQUIRED  AS NEW PARTS ACCOMPANIED BY PROPER PART CERTIFICATIONS. BEARINGS WERE MANUFACT UNDER P/N CB17663. ALL INSPECTED & RECALLED BEARINGS WERE FROM PRODUCTION LOTS 64598, 61262, 61077.  A TOTAL OF 120 BEARINGS EXAMINED.  A FAILURE RATE PER LOT FROM 25-50 PERCENT.  OBSERVED THAT WHEN GREASE APPLIED THROUGH APPROPRIATE NEEDLE ZERK, THE ORFICE BALL FORCED TO BOTTOM OF THE GREASE ORFICE BLOCKING THE ENTRY OF GREASE TO THE BEARING SURFACE.
