7.7. ACTUATOR ASSEMBLY / DISASSEMBLY
Do not apply compressed air until the disassembly/assembly process is completed. The figure is a
schematic representation of some of the steps in the actuator disassembly process.
7.7.1. Disassembly
1. Fully loosen regulating screw (22) to remove nut (26) and
regulating screw (22).
2. Remove air-fitting (18).
3. Position the actuator in the base of the clamp or in the lathe
collet. A thick tube (102) and a shim (101) must be used on
actuator base cover (12).
4. Apply force to the shim (101). Once the cover (12) has
dropped some distance, remove the snap ring (45), this
should have sufficient free space to be able to remove it.
5. Reduce the force on the shim (101) slowly until the top cover
is free (you will note that the spring no longer exerts
pressure).
6. Remove the actuator base cover (12).
7. Remove lock ring (45B) to separate piston (30) from shaft
(08).
8. Remove spring (06).
9. Take out the seals (20A and 20B), the scraper (60) and the
guide (11) from the cover (12).
10. Take out the seals (20 and 20C) from the piston (30).
11. Remove actuator stop (43) from actuator body (01).
7.7.2. Montaje
1. Insert actuator stop (43) inside the actuator body (01).
2. Fix regulating screw (22) in actuator stop (43) and tighten it
with actuator nut (26).
3. Insert spring inside the body (06).
4. Mount the scraper (60), seals (20A & 20B) and guide (11) on
actuator base cover (12).
5. Mount seals (20 and 20C) on the piston (30).
6. Fix piston (30) on actuator shaft (08) with the help of lock
ring (45B).
7. Locate actuator shaft (08) inside actuator base cover (12).
8. Slide the assembly of piston (30), actuator shaft (08) and
actuator base cover (12) inside the actuator body (01).
9. Hold the actuator assembly into clamp and place a thick tube
(102) and a shim (101) as shown in figure beside.
10. Apply force on the shim (101) so it lowers by some distance.
Insert the snap ring (45).
11. Reduce the force applied slowly until the tool no longer
touches the cover.
12. Install air-fitting (18).
13. Apply compressed air to check the proper functioning of the
actuator.
