e. Install the positioner on the actuator by placing
the bracket (key 64) around the appropriate
actuator leg. Visually center the center line of the
slot in the feedback plate (key 68) with the center
line of the hole in the housing. Then, tighten the
nuts (key 66) only tight enough to prevent the
positioner from moving on the actuator leg.
Locate the feedback lever assembly (key 19) so
that it may be temporarily installed into the
positioner housing (key 1) and the feedback plate
(key 68) to verify alignment. Do not install the
range spring at this time. Place the pilot shaft
(key 19A) in the slot of the feedback plate, and, at
the same time, insert the feedback shaft in the
hole of the positioner housing. Depress the
feedback lever assembly inward until it stops
against the housing. Make certain the slots in
both the feedback lever assembly and the
feedback plate are horizontal with each other and
that the feedback lever assembly and the
feedback plate are parallel with each other. If
necessary, correct alignment by loosening the
hex nuts (key 66) and moving the positioner on
the actuator leg as required.
f. Tighten the two hex nuts (key 66) to secure the
positioner to the actuator leg.
g. Install the feedback lever assembly and range
spring.
