On the travel indicator side of the actuator:
9. Screw the left‐hand threaded hex nut (key 71) onto the piston rod (key 10) as far as possible.
10. Screw the turnbuckle (key 70) onto the piston rod as far as possible. Only finger‐tighten it, as this adjustment will
be changed in a later step.
11. Screw the hex nut (key 11) onto the rod end bearing. Then thread this assembly completely into the turnbuckle.

12. To aid installation of the lever, apply lithium grease lubricant (key 93) to the valve shaft spline.
For size 80, 100 and 130 actuators, it may be necessary to rotate the set screw (key 82) clockwise slightly to spread the
split portion of the lever and allow installation on the valve shaft.
13. Refer to the appropriate valve instruction manual for lever/shaft orientation marks, and slide the lever into place.
Refer to figure 3 for the appropriate lever operating clearance.
D For size 80, 100 and 130 actuators, when the lever is in place, back off the set screw (key 82) so the lever can be
clamped onto the valve shaft.
