Subtask 27-44-54-720-051
A. Functional Test of the Pressure-Off Brakes (2):
(1) Cut and remove the lockwire which safeties the plug (3) to the screw (5) at the THS actuator motor (6).
(2) Remove the plug (3) from the manual drive input of the THS actuator (1).
(3) Remove and discard the O-ring (4) from the plug (3).
R R (4) Use a torque wrench to between 1.0 and 10.0 m.daN (88.49 and 884.95 lbf.in) for the subsequent test.
R R (5) Put the torque wrench in position at the manual drive input, apply a torque of minimum 7.2 m.daN (53.0973 lbf.ft). Make sure that the pressure-off brakes do not move.
R R R NOTE : The static break-out torque must be a minimum of 7.2 m.daN____ (53.0973 lbf.ft). - If the static break-out torque is between 6.5 m.daN (47.9351 lbf.ft) and 7.2 m.daN (53.0973 lbf.ft), replace the THS actuator within the next A-Check (500 F/H) (Ref. TASK 27-44-51-000-001) and (Ref. TASK 27-44-51-400-001). - If the static break-out torque is less than 6.5 m.daN (47.9351 lbf.ft), replace the THS actuator before next flight (Ref. TASK 27-44-51-000-001) and (Ref. TASK 27-44-51-400-001).
R (6) Remove the torque wrench.
R (7) Apply COMMON GREASE (Material No. 04-015) to the new O-ring (4).
R (8) Use the CONE - MOUNTING, THS ACTUATOR (0U145506) and put the O-ring (4) on the plug (3).
R (9) Install the plug (3) in the manual drive input.
R (10) TORQUE the plug (3) to between 1.4 and 1.6 m.daN (10.32 and 11.79 lbf.ft).
R (11) Safety the plug (3) to the screw (5) at the motor (6) with lockwire 0.6 mm (0.024 in.).
