ASSEMBLE THE ACTUATOR
(see Figs. 1 + 2)
8.1
Assemble diaphragm housing
8.1.1
Fit bushing (11) and wiper ring (16) to diaphragm
housing.
8.1.2
Enter backup ring (9), O-ring (10) and backup ring (9)
from the other side.
8.1.3
Fit the ring (8) and calk in three positions.
8.2
Assemble guide bushing (33)
8.2.1
Fit bushing (11) and wiper ring (16).
8.3
Assemble diaphragm
8.3.1
Clamp the actuator stem in a vice (protect the stem
against surface damage).
8.3.2
Fit the split rings (6) in the groove in the actuator stem
and place the plate (5) on top.
8.3.3
Fit the diaphragm (4) on top of the plate (5) ensuring
that the inner bead sits correctly in the groove ma-
chined into the plate (5)
8.3.4
Place the O-ring (10) over the actuator stem until it sits
in the plate (5).
8.3.5
Place the diaphragm plate (3) over the actuator stem
(24) onto the diaphragm (4).
8.3.6
Place the sleeve (28) over the actuator stem. Screw the
nut (30) onto the sleeve (28) until the split ring (6) can
be fitted into the groove in the actuator stem. Rotate the
nut (30) anticlockwise to clamp the diaphragm and
torque the nut to the value shown in table 1. Tighten the
locking screw (29).
8.4
Assemble actuator
8.4.1
Place the ring (7) in the centre of the diaphragm
housing (12).
8.4.2
Fit the actuator stem assembly to the diaphragm hous-
ing (12) ensuring the that outer bead of the diaphragm
sits correctly.
8.4.3
Replace Spring housing (25) and secure with 24 screws/
nuts (26/23) (torque values see table 1).
8.4.4
Replace spring guide (31) (if used). Replace spring(s)
(43) ensuring they are situated correctly within the
rollpins (2).
8.4.5
Place the plate (34), complete with cap (39) and guide
bushing (33), onto the springs and tighten the 8/10
screws (38), crisscross, and in equal measures until
the plate contacts the spring housing (torque values
see table 1).
WARNING:
NEW SCREWS (38) must be used EVERY
time. Grease the screws before fitting.
