 (a)  
Put the RRCA (37) in its correct position. Make sure the anti-rotation clevis (14) is engaged.

 (b)  
Install and tighten the bolt (11), washer (38), and nut (12).

 S 422-034
 (2)  
Do this step to connect the RRCA (37) to the left ratio changer crank (9).

 (a)

 (3)  
Connect these components to the RRCA:

 (a)  
the electrical connectors (26, 33)

 (b)  
the hydraulic hoses (15, 18, 19).

 S 822-080
 (4)  
Do the Rudder Ratio Changer Actuator - Oscillation Check
 (AMM 27-21-00/501).

 S 862-099

 (5)  
Make sure rig pins R5 and R6 can be easily installed and removed at the same time. If you cannot easily install and remove rig pins R5 and R6, do the adjustment procedure for the rudder ratio changer mechanism (AMM 27-21-00/501).

 S 422-100

 (6)  
If the RRCA support clevis was removed at the time of RRCA removal, do the RRCA Adjustment (AMM 27-21-00/501).

 NOTE: The rudder ratio changer and the rudder system rigging
____ are very sensitive to the shimming of the RRCA support clevis. If the clevis was removed to make the removal of the RRCM easier, the clevis must be installed (AMM 27-21-12/201). This can require the adjustment of the RRCA support clevis shims and system rigging (AMM 27-21-00/501).
