Disassembly instruction of the yoke
NOTICE
Limit disassembly only to necessary compo-
nents.
1. Fix the actuator on the assembly table, if this is not
already happened (see also pages 14 - 15).
2. Remove the socket head screw (214) and the stroke
indicator (216).
3. Unlock the lock nut (344) counter-clockwise.
4. Loosen the actuator coupling (249) and lock nut (344)
clockwise.
5. We recommend you not to remove the actuator from
the yoke. If this is indispensable mark the position,
loosen the actuator locknut (256) clockwise and lift off
the actuator and O-ring (271).
NOTICE
Use a rounded chisel and a hammer.
6. Store all coupling and yoke-parts safely, lose no parts.
7. For disassemble the attachments see pages 26 - 33
and for actuator subassembly see pages 18 - 25.
Reassembly instruction of the yoke
8. Lubricate the threads of the actuator and stroke cou-
pling-parts with an appropriate lubricant.
9. If necessary mount new O-rings (278, 271) and the ac-
tuator onto the yoke (201) put in line with the mark and
tighten the actuator locknut (256) counter-clockwise.
The vent plug shall be at a right angle to the yoke legs.
NOTICE
Use a rounded chisel and a hammer.
10. Screw in the lock nut (344) and the actuator coupling
(249) - screw-in depth once thread diameter - counter-
clockwise and fix it. Aligning the coupling parallel to
the yoke.
11. Further reassembling steps are only possible with the
valve (see page 39).
