2-3 Disassembly of Translating Tube Actuator
1. Use the appropriate disassembly procedure. If the lifting nut is outside the actuator on the
screw, it is a traveling nut integrated actuator; this is also called a “rotating screw” actuator. If
the nut is not positioned outside the actuator sleeve, it is a translating tube integrated actuator.
2. Handle all machined parts with care and maintain an “order of disassembly” to aid in re-
assembly.
3. The motor is optional. It is not user serviceable.
4. Disconnect power from the integrated actuator before proceeding.
5. To remove the motor, secure the integrated actuator in a work holding device such as a bench
vise. Do not clamp onto the protection tube (4) or translating tube assembly (13).
6. Remove the four hex head screws and washers (26 & 27) that attach the motor to the flanged
sleeve (1). Remove the motor.
7. Remove the coupling half (23) and key (24) from the worm shaft.
8. Remove the seal (9) and retaining ring (8).
9. Use a tool to tap on the flange end of the worm shaft (6). This will loosen and unseat the worm
shaft bearing (7) and permit disassembly.
10. Loosen the two set screws (5) and unthread the protection tube (4). The upper thrust bearing
(2) and the seal (20) may be exposed (or they may remain inside the protection tube when it is
removed).
11. Disassemble the protection tube (4) from the translating tube assembly (11, 12, 13, 16, 25).
12. Disassemble the translating tube assembly from the sleeve (1) by firmly pulling upward, away
from the sleeve (1).
