(14) Apply LOCTITE to the hexagon socket head cap
screws. Tighten the screws with a torque wrench to
fasten the base plate securely with the torque shown in
[Table 13]. Tighten the screws diagonally and evenly.
LOCTITE: Henkel Corporation Loctite 242 or 243
(15) Replace all cover packings ㉗ .
(16) Apply grease (lithium soap-base, consistency No.2) to
the cover packing ㉗ . Grease application amount for
each type is show in [Table 14].
(17) Install the cover 1 ⑥ and the cover 2 ⑦ so that the
bosses of the covers face the side opposite to the
full-close stopper bolt side. Install the cover 1 ⑥ and the
cover 2 ⑦ with the hexagon socket head cap screws ㊼
and the spring washers ㊻ to the case. At this time, do
not forget to assemble the cover packing ㉗ in advance.
[Fig. 39]
Please note that insufficient clamping force of the bolts
causes looseness of the bolts, resulting in defective
operation or falling of the cylinder.
Install the cover 1 ⑥ and the cover 2 ⑦ to the left side
and the right side respectively while facing the full-close
stopper bolt. Please note that wrong cover installation
causes defective operation, such as air leakage.
Forcible assembly of single-acting type cylinders, such as
uneven tightening of the hexagon socket head cap screw
to mount the cover, may cause flying out of the spring,
which would result in a dangerous situation.
Install the covers of single-acting type cylinders according
to
5-4 Single-acting type cylinder side cover assem-
bly procedure .

(18) Tighten the hexagon socket head cap screws ㊼ to
mount cover1 ⑥ and the cover2 ⑦ securely with the
torque shown in [Table 15].

(11) Install the stopper ④ to the underside of the shaft ② so
that the stamp "A" can be seen when the cylinder is
seen from the bottom.
Stopper assembly direction for pressure-closing single-
acting type (7F) is different from that of double-acting
type (7E) and pressure-opening single-acting type (7G).
[Fig. 34][Fig. 35]
(12) Apply grease (lithium soap-base, consistency No.2) to
both sides of the thrust plate ⑲ . Please use the applica-
tion amount shown in [Table 12]. After applying grease,
install the thrust plate ⑲ to fit the groove of the base
plate ⑧ . [Fig. 36]
Assembly direction of the stopper ④ for pressure-opening
single-acting type cylinder is different from that of
pressure-closing.
Assembly with wrong direction causes defective operation,
such as reverse opening/closing operation of the valve.

• Apply liquid gasket to the designated area on the base plate ⑧ completely. [Fig. 37]
Liquid gasket ： ThreeBond 1207D or an equivalent

(13) Make sure to remove water, oil, other dust from the application area, and apply liquid gasket to the designated
area on the base plate completely. Be careful to avoid applying liquid gasket to the thrust plate ⑲ . Otherwise,
defective operation is caused.
