(g) (h) Do a check between the trunnion and the gimbal ring for 0.000 to 0.003 inch (0.000 to 0.076 mm) clearance.If it is necessary, install shims to obtain the gap.
NOTE:____ Shims must be equal on the two sides within 0.003 inch (0.076 mm).
(i) (j) Install the retainers and the bolts. 1) Tighten the bolts.Connect the hydraulic line to the RET (retract) port. 1) Tighten the hydraulic line connection at the center or bottom actuator to 255 pound-inches (28.9 Nm).
NOTE:____ Tighten the hydraulic connections that have been disconnected to 255 pound-inches (28.9 Nm), then loosen and retighten them to 255 pound-inches (28.9 Nm). Fittings with O-rings should not be double-torqued.
(k) 2) Loosen and tighten the connection again to 255 pound-inches (28.9 Nm).Do these steps to temporarily connect the flex shaft(s) to the actuator to be able to manually translate the sleeve.
NOTE:____ If you install a center actuator, do these steps at the upper and lower sides of the actuator.
1) Push the tube coupling nut and the adapter (View B, Fig. 401) along the tube as it is necessary to expose the flex shaft end.
2) Engage the flex shaft with the worm gear shaft in the actuator.
NOTE:____ Tighten the hydraulic connections that have been disconnected to 255 pound-inches (28.9 Nm), then loosen and retighten them to 255 pound-inches (28.9 Nm). Fittings with O-rings should not be double-torqued.
