## Discrepancy

FLIGHT CREW AND CABIN CREW DETECTED A STRONG ODOR CIRCULATING ABOUT THE ACFT WHILE CLIMBING THROUGH FL300. CREW DESCENDED THE ACFT TO FL250 AND COMPLETED QRH PROCEDURES.  ODOR DISSIPATED WITH SECURING GALLEY POWER AND THE FLIGHT CONTINUED TO SCHEDULED DESTINATION.  MX FOUND AN O-RING LEAKING ON THE HYD PRESSURE RELIEF VALVE IN THE LEFT WHEEL WELL AND REPLACED IT AND ALSO CLEANED HYD FLUID RESIDUE FROM AROUND THE APU INLET. THE NR 2 COFFEEMAKER WAS REPLACED DUE TO FACT THAT THE ODOR WENT AWAY WHEN THE GALLEY POWER WAS TURNED OFF.
