 (1) Make sure that you cannot put a feeler gage with a thickness of 1.2 mm (0.0472 in.) into the gap (Ref. Fig. 503/TASK 27-44-00-991-004) between the input plate and the ball carrier of the control valve detent.
 (2) If the control valve detent is centered, use permanent ink to put two reference marks in line (if not already marked). Put one of the reference marks on the input plate, the other on the ball carrier.
 NOTE : The control valve detent is centered when the feeler gage does____ not go in the gap.
 (3) If the feeler gage goes in the gap, you must center the control valve detent again as written below:
 Subtask 27-44-00-820-050
 C. Recenter the left and the right control valve detents: 
R R R R R  CAUTION : BE CAREFUL WHEN YOU INSTALL OR REMOVE THE JAMMING SIMULATION_______ TOOL. PUSH OR PULL THE TOOL AND TURN THE MECHANICAL INPUT SHAFT AT THE SAME TIME. DO THIS UNTIL YOU FIND THE POSITION WHERE YOU CAN INSTALL OR REMOVE THE TOOL EASILY. THIS WILL PREVENT DAMAGE TO THE VALVE CONTROL SHAFT AND THE TOOL.
 NOTE : The subsequent steps are not necessary if the control valve detent____ is centered (see above).
 NOTE : The procedures for the left and the right control valve detents____ are the same. Therefore only one is described.
 (1) Put one of the two sides (LH or RH which is applicable) of the TOOL -JAMMING SIMULATION (0U190857) on the splined end of the valve control shaft.
 NOTE : Use the side (N.UP or N.DN) of the TOOL - JAMMING SIMULATION____ that puts the spigot nearest to the recess.
 (2) Turn the mechanical input (1) of the THS actuator until the tool fits in the recess. (Ref. Fig. 501/TASK 27-44-00-991-001)

 

 NOTE : When the detent is centered, you can hear a "CLICK".
____
 (4) If the side with the LH or RH A/C N.UP on the tool is installed, turn the mechanical input (1) counterclockwise (CCW) until the detent is recentered.
 NOTE : When the detent is centered, you can hear a "CLICK".
____
 (5)
 Make sure that you cannot put the feeler gage with a thickness of 1.2 mm (0.0472 in.) into the gap between the input plate and the ball carrier of the control valve detent.

 (6)
 Use permanent ink to put two reference marks in line (if not already marked). Put one of the reference marks on the input plate, the other on the ball carrier. (Ref. Fig. 503/TASK 27-44-00-991-004)

 (7)
 Remove the TOOL - JAMMING SIMULATION from the splined end of the control valve input shaft.

 E. Preparation for the Test
 (1)
 Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).

 (2)
 Pressurize the Green and the Yellow hydraulic systems (Ref. TASK 29-23-00-863-001).

 (3)
 Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).

 (4)
 On the center pedestal on the ECAM control panel, push the F/CTL pushbutton switch.

 (5)
 Make sure that, on the lower Display Unit (DU) of the ECAM, the F/CTL page comes on.

 (6)
 Use the interphone or an equivalent system to communicate between the cockpit and the fuselage tail section.

 4. Procedure
_________
 (Ref. Fig. 501/TASK 27-44-00-991-001, 502/TASK 27-44-00-991-003, 503/TASK
 27-44-00-991-004)
 NOTE : Do the test in four steps.

____ Subtask 27-44-00-710-050 R A. Do the test in the electrical mode of the RH valve block. WARNING : MAKE SURE THAT THE CONTROL VALVE DETENTS ARE CENTERED EACH TIME
_______ YOU COMPLETE ONE OF THE FOUR TEST STEPS. IF THE DETENTS ARE NOT CENTERED, THE AIRCRAFT WILL NOT OPERATE CORRECTLY.
 CAUTION : USE ONLY THE SPECIFIED TOOL. YOU CAN CAUSE DAMAGE TO THE
_______
 ACTUATOR IF YOU USE A DIFFERENT TOOL.

 CAUTION : BE CAREFUL WHEN YOU INSTALL OR REMOVE THE JAMMING SIMULATION
