## Discrepancy

WHILE SELECTING GEAR DOWN, NR 2 MAN HYDRAULIC PRESSURE WENT TO ZERO, NO GEAR EXTENDED AT THAT POINT.  LOUD GRINDING NOISE WAS HEARD AFTER GEAR SELECTED DOWN, PERFORMED ALTERNATE EXTENSION.  JACKED ACFT, CHECKED ENG DRIVE HYD PUMP FOR AIR LEAKS, BLED SYSTEM, AND CYCLED GEAR SEVERAL TIMES.  REMOVED AND REPLACED PSEU FOR TROUBLESHOOTING, OPS CHECKS GOOD.  ACFT RETURNED TO SERVICE.  (W)
