marked, heat the hex nut (key 14) to 177_C(350_F) long enough for the thread locking adhesive (medium
strength) (key 92) to lose its holding strength. Then, remove the cap screw and hex nut (keys 13 and 14).
CAUTION
Do not use a hammer or similar tool to drive the lever (key 28) off the output shaft. Driving the lever could damage
operated equipment. For valves, driving the lever could move the valve disc and bearings away from the centered position
causing subsequent damage to valve parts.
If necessary, use a wheel puller to remove the lever. It is permissible to tap the wheel puller screw lightly to loosen the
lever, but hitting the screw with excessive force could damage the operated equipment.
3. Loosen the cap screw (key 29) and remove the lever (key 28) from the output shaft (key 94).
4. For an actuator with a J mounting adaptation,
a. Unscrew the cap screws (key 24), and remove the actuator housing (key 21) from the mounting yoke (key 23).
b. Rotate the actuator housing to the new position (1, 2, 3, or 4).
c. Secure the actuator housing to the mounting yoke with the cap screws (key 24). Tighten the cap screws to the
torque value listed in table 7.
5. For an actuator with an H mounting adaptation,
a. Unscrew the cap screws (key 87) and loosen the actuator assembly from its mounting bracket.
b. Rotate the actuator housing to the new position (1, 2, 3, or 4).
c. Secure the actuator housing to the mounting bracket with the cap screws (key 87). Tighten the cap screws to the
torque value listed in table 7.
6. Referring to the alignment marks that were made in step 2, install the lever (key 28) onto the output shaft (key 94)
as follows:
a. If the new actuator position is 90 degrees clockwise from the previous actuator position, install the lever so that
its orientation mark is located 90 degrees clockwise from the mark on the output shaft.
b. If the new actuator position is 90 degrees or 180 degrees counterclockwise from the previous position, install the
lever so that its orientation mark is located either 90 degrees (for 90 degrees) or 180 degrees (for 180 degrees)
counterclockwise (respectively) from the mark on the output shaft.
c. Slide the lever onto the output shaft with the bolt holes in the lever aligned as closely as possible with the hole in
the rod end bearing (key 12). Then, temporarily rotate the lever and output shaft until the rod end bearing no
longer interferes with further installation of the lever, and slide the lever as far as it c an go onto the output shaft.
Clamp the lever to the output shaft with the cap screw (key 29). Tighten the cap screw to the torque value listed
in table 7.
d. Rotate the lever and output shaft back to the original position, and then adjust the rod end bearing so that it can
be attached to the lever.
7. Apply thread-locking adhesive (medium strength) (key 92) to the threads of the cap screw (key 13).
8. Connect the lever (key 28) and the rod end bearing (key 12) with the cap screw and hex nut (keys 13 and 14). This
connection can be aided by stroking the actuator from its up travel stop with a regulated air source. Tighten the cap
screw to the torque value listed in table 7.
9. Note the position of the valve or other operated equipment and direction of rotation.
