2-6 Assembly of Translating Tube Actuator
1. Rest the actuator sleeve (1) on a work surface with the flange downward.
2. Install the worm shaft bearing (7) into the sleeve (1). Do this by passing the worm through the
wide opening at the side of the sleeve. Position it over the worm shaft opening. Seat the
bearing with a tool.
3. Rotate the sleeve (1) so it rests on the base.
4. Assemble the O-ring lower thrust bearing (2) and O-ring (19)
5. Set the sleeve aside and continue.
6. Extend the threaded end of the translating tube assembly into the
7. Insert the worm shaft (6) through the sleeve (1) toward the flange. Inside the sleeve, this will
pass in front of the already assembled worm gear nut nut (3) and through the previously
installed worm shaft bearing (7).
8. Install the other worm shaft bearing (7) over the end of the worm (6). Seat this in place.
9. Install the retaining ring (8).
10. Check that the worm shaft (6) rotates when turned by hand. Loosening or tightening the
threaded connection between the sleeve and the protection tube makes adjustments to the
stiffness of rotation of the worm shaft.
11. Spot drill through the threaded holes in the sleeve (1) and insert the set screws (5).
12. Thread the air vent (17) and Pipe Plug (21) in to the protection tube.
13. Insert and seat the two worm shaft seals. Exercise care so the seals are not damaged on any
sharp surfaces. Note: These seals are difficult to remove. Once they are removed, they must
be replaced.
14. Use the key (24) to attach half the coupling (23) to the worm shaft.
15. Attach the other half coupling (23) to the motor shaft.
16. Join the motor to the integrated actuator via the coupling. Align the motor mount holes to the
mounting holes on the flange. Use lock washers and screws (27, 28) to fasten the motor to the
integrated actuator.
17. Insert grease fitting (28) into the sleeve and partially fill the cavity with Ronex Extra Duty 1
grease.
18. Insert the pipe plug (21) in the sleeve.
