9. Back off the nut (74) against clevis (7). Apply Loctite 271
on the threads of the actuator rod. Tighten nut against
clevis by applying torque from (Table 3), as the nut is
being tightened, firmly hold the clevis with a wrench,
since the unsupported driver arm may tend to tip over.
10. Slowly release air pressure. Assemble cover by using
the socket head screws (21). Apply tightening torque
per (Table 3).
11. Install the indicator pointer (24) if this was previously
disassembled. In female actuators make certain that
the indicator points to the inscribed line in the driver
arm. In male actuators, hold the indicator pointer
in place with a retaining ring (9). NOTE: Refer to
Installation instructions for spring-to-close or spring-
to-open configuration.
