## Discrepancy

SUBMITTER RECEIVED 3 PARTS FROM STOCK OVER A PERIOD OF TIME THAT HAD THE BEARING PARTIALLY DISASSEMBLED.  ONE RECEIVED INTACT.  INSTALLED THE ASSY IN THE PUMP AND DURING THE RUN-IN PROCESS, THE LOWER BEARING CAME APART CAUSING FAILURE TO THE PUMP.  SUBMITTER STATED BETTER QUALITY INSPECTIONS REQUIRED.
