 4. Procedure_________
 (Ref. Fig. 501/TASK 27-44-51-991-011)
 Subtask 27-44-51-710-050
 A. Operational Test
 (1) Cut, remove and discard the lockwire at the plug (3) of the manual drive input.
 (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) Install the RELEASE TOOL - PRESSURE-OFF BRAKE, THS ACTUATOR (0U190844) on the control piston (2) of one of the two pressure-off brakes as follows:
 (a) Install the shaft on the thread of the control piston (2).
 (b) Put the collar in position on the shaft and install the command nut.
 (c) Make sure that the collar has contact with the housing and there is a gap between the spring pin and the collar.
 (d) Make sure that the command nut has contact with the collar.
 (e) TORQUE the command nut to between 0.35 and 0.50 m.daN (30.97 and 44.24 lbf.in) (agrees with half a turn of the command nut) to release the pressure-off brake.
 (5) Put a socket wrench in position at the manual drive input.
 (6) Use the socket wrench to turn the manual drive input (a maximum of half a revolution), very slowly, in one direction and then in the other direction.
 NOTE : Listen for the operation noise of the ratchet wheels, (a____ tic-tac noise), while the manual drive input turns.
 NOTE : When you turn the manual drive input in the clockwise or____ counter- clockwise directions, an intermitted resistance to the movement can occur, due to compression of hydraulic fluid in the hydraulic motors. 
R R  (7) Remove the RELEASE TOOL - PRESSURE-OFF BRAKE, THS ACTUATOR (0U190844) from the control piston (2).

 (4) on the plug (3).

 (11)
 Install the plug (3) in the manual drive input.

 (12)
 TORQUE the plug (3) to between 1.4 and 1.6 m.daN (10.32 and 11.79 lbf.ft).

 (13)
 Safety the plug (3) with lockwire, corrosion-resistant steel, dia 0.6 mm (0.024 in.).
