What was found

AFTER APPROX 65 HOURS SINCE THE NOSE STRUT WAS LAST RESEALED, IT WAS LEAKING BADLY AND NEEDED TO BE RESEALED AGAIN. HYD FLUID WAS COMING FROM THE LOWER GLAND OF THE TRUNNION SUGGESTING THAT THE BOTTOM POLY PACK SEAL WAS LEAKING. AFTER IT WAS DISASSEMBLED, THE SEAL WAS INSPECTED FOR DAMAGE, BUT THERE WAS NOTHING APPARENTLY WRONG. ON THE CHAMFERED EDGE OF THE BARREL, THERE WAS SOME BALL LIKE SUBSTANCE ALMOST LIKE IT WAS RESIDUAL MATERIAL THAT HAD ADHERED TO THE EDGE FROM THE CHROME-ING PROCESS. IT IS HARD TO TELL IF THE VERY SMALL BALLS OF CHROME COULD SCAR THE SEAL ENOUGH THAT IT STARTS TO LEAK AFTER BEING IN SERVICE FOR APPROX 50 HOURS. AFTER CLEANING UP THE BARREL AND LUBING, THE STRUT WAS REASSEMBLED AND SERVICED WITHOUT ANY FURTHER DEFECTS FOUND.
