Disassembly
2.
For Spring-return actuators, do the following:
a.
Tip:
For actuators with assembly code CW, turn back the right hand limit
stop screw (30) 2 full turns.
For actuators with assembly code CC, turn back the left hand limit stop
screw (30) 2 full turns.
This will lower the spring force on the end cap and reduces the screw out
length of the end cap screws.
b.
Uniformly loosen the screws (9) of the end caps (5) 1/4-1/2 turns at a
time, in sequence, as per figure 18, to relieve the pre-load of the springs.
c.
Remove the o-rings (11) and "B" port seals (2). Discard these parts.
