## Discrepancy

(CAN) SHIMMY WHEN TAXIING & NECESSARY TO CENTRE THE NOSE GEAR MANUALLY IN ORDER TO GET THE GEARS TO RETRACT ON TAKEOFF.   AFTER INVESTIGATION IN COLLABORATION WITH THE O/H FACILITY (THE GEAR WAS FRESHLY O/H), WE FOUND THAT IN THE NOSE STEERING RACK ACTUATOR, BOTH SLEEVES P/N 14564 HAD BEEN REINSTALLED WITH DAMAGED LOCKING FEATURE AND THUS RENDERING PROPER ADJUSTMENT OF THE CENTERING MECHANISM IMPOSSIBLE. AT ALL TIME THE PRESENCE OF A 10 DEGREE PLAY WAS THE CAUSE OF THE IMPOSSIBILITY TO ADJUST.  THE PROBLEM HAS BEEN FIXED BY REPLACING THE STEERING RACK ACTUATOR BY A NEWLY O/H UNIT.
