5-2 Single-acting type cylinder side cover disassembly procedure
[Fig. 23]
[Fig. 24]
[Fig. 25]
When taking out the side covers of single-acting type
cylinders for disassembly, the internal spring may fly out,
resulting in a dangerous situation. When disassembly is
required, follow the instructions given below for safe work.
For the actuator type T750S, the spring length has been
returned to the free length when taking out the standard
bolts.
1) Take out pneumatic pipelines from this product, and
check that internal compressed air, etc. is discharged
completely from this product.
2) Make sure that no damage, such as cracks, deformation
and chipping, is noticed on the covers (Cover 1 ⑥ ,
Cover 2 ⑦ ). If any damage is noticed, stop work and
replace the whole actuator because the actuator is
dangerous.
3) During work, be careful to avoid workers standing on the
extension of the longitudinal direction line of the cylinder
until the spring is taken out as a precaution.
4) Please prepare two bolts for disassembly with the size
shown in [Table 7] (Not required for T750S.)
5) Take out two diagonally-mounted the "hexagon socket
head cap screws ⓑ and ⓓ " [Fig. 23] (Not required for
T750S.)
6) Apply grease to the thread part of the prepared "bolts for
disassembly", insert them to the holes where the "hexa-
gon socket head cap screws ⓑ and ⓓ ” have been taken
out. Then screw in the bolts to the length shown in [Table
8] and tighten them. [Fig. 23] (Not required for T750S.)
7) Loosen the "hexagon socket head cap screws ⓐ and ⓒ "
alternately. When the cover and the "bolts for disassem-
bly ⓑ and ⓓ " make contact, loosen all the bolts in
diagonal sequence evenly and alternately. [Fig. 24]
8) When the dimension A in the figure is the length of [Table
9], the "hexagon socket head cap screws ⓐ and ⓒ "
which are not replaced will come out. [Fig. 25] (Not
required for T750S.)
9) Loosen the rest two "bolts for disassembly ⓑ , ⓓ " evenly
and alternately. (Not required for T750S.)
10) When the bolts for disassembly (standard bolts in the
case of T750S) come off, the spring is stretched fully.
Thus the side cover can be taken out safely.
11) Take out the side cover and the spring ㊷ straight away.
12) Take out the side cover at the opposite side in the same
way.

(4) Loosen the hexagon socket head cap screws ㊾ , and
take out the spring washers ㊿ , the base plate ⑧ , and
the thrust plate ⑲ . [Fig. 19]
The quantity of the hexagon socket head cap screws ㊾
and the spring washer ㊿ depend on the type. Please
refer to [Table 6] for details.
(5) Turn the shaft ② until the sunk plug ㉛ mounted at the
side of the yoke ③ can be seen, then loosen the sunk
plug ㉛ and take out the connecting pin ㉚ . [Fig. 20]
(6) Take out the shaft ② and the stopper ④ in the direction
of the arrow.
When taking it out, be careful not to damage the bearing
