## Discrepancy

REJECTED TAKEOFF AT 85 KTS DUE TO THE NR 2 N1 GAUGE BEING VERY SLOW TO REACT AND NOT READING ABOVE 60 PERCENT N1.  THE NR 2 THROTTLE WAS ALSO SLOW TO REACT BUT DID MATCH THE N1 THROTTLE.  REF. N/R 4484876, 4457301 FOR CORRECTIVE ACTION.  REMOVED AND REPLACED MEC NR 2 ENGINE PER AMM 73-21-01.  VBV AND VSV FEEDBACK CABLE TESTS CHECK GOOD.  SEE N/R 4484876 FOR LEAK AND OPS CHECK.
