H. Install the Reaction Link (Fig. 201)
S 432-036
(1)
Do these steps to install the reaction link (3) on the trunnion block (19):
(a)
Install the end cap (33) on the top side (when installed on the airplane) of the trunnion block (19).
(b)
Put the reaction link (3) on the trunnion block (19) and do this step: 1) Install the pin (34), bolt (30), washer (31), and the nut
(32)
that connect the reaction link to the end cap. Tighten the nut to 145-165 pound-inches (16.4-18.6 newton-meters).
(c)
Lubricate the PCA and reaction link grease fittings after installation.
S 422-037
(2)
Do these steps to install the actuator, reaction link, and trunnion block assembly:
(a)
Align the trunnion block (19), actuator (12), and reaction link (3) assembly with the airplane connection points.
(b)
Install the bolt (27), washer (28), and the nut (29) that connect the hanger link (26) to the trunnion block (19). Tighten the nut to 60 - 95 pound-inches (6.8-10.7 newton-meters).
(c)
Turn the actuator (12) and the reaction link (3) until they are aligned with the rudder front spar (4).
(d)
Install the bolts (5), washers (7), bushings (6), and nuts (8) that connect the actuator and the reaction link to the rudder front spar. Do these checks: 1) Make sure the torque that is necessary to turn the nut
before it touches the spar is 90 - 400 pound-inches (10.2-45.1 newton-meters). 2) Tighten the nut to 1000 - 1400 pound-inches (113-158 newton-meters).
