## Discrepancy

TWO OF THE CRITICAL SHAFTS IN THE MECHANISM WERE UNDER THE MINIMUM END SHAKE CALLED OUT IN THE OVERHAUL MANUAL.  THEY MEASURED .0005 INCH AND .0009 INCH (O/H MANUAL CALLS OUT .0020 INCH MINIMUM).  SUBMITTER STATED THIS UNDER ENDSHAKE CONDITION COULD CAUSE A POINTER HANG-UP UNDER COLD CONDITIONS.
