 (5)  S 624-073Apply a layer of sealant to the mating surface of the PCA (9), and put the PCA against the faying surface of the trunnion (4).
 (6)  S 434-074Install the bolts (1), washers (2), and nuts (3) on the PCA with wet sealant.
 (7)  S 434-075Tighten the nuts to 90-125 pound-inches (10.2-14.1 newton-meters).
 (8)  S 644-076Apply a layer of sealant to the mating surface of the reaction link bearing (21), the assembled reaction link (19) and its bearings (21), and the trunnion (4).
 (9)  S 434-077Install the bolts (23), washers (24), and nuts (25) to the reaction link with wet sealant.
 S 434-078

 (10) Tighten the nuts to 90-125 pound-inches (10.2-14.1 newton-meters).
 NOTE: Make sure the trunnion (4) and the flanged spacers (21)
____ can turn freely.
 S 434-079
 (11)
 Move the trunnion (4) into the idler link (13) and install the bolt (26), washers (27), bushing (28), and nut (29) with BMS 3-33 grease. BMS 3-33 (recommended), BMS 3-24 (optional).

 S 434-080

 (12)
 Move the reaction link rod end (20) and the PCA rod end (12) to the elevator spar fitting and install the bolts (14), washers (15, 17), bushings (16) and nuts (18) with BMS 3-33 grease. BMS 3-33 (recommended), BMS 3-24 (optional).
