Actuator Disassembly
Section 2 - Actuator Disassembly is written to either completely disassemble
the entire actuator or can be used to disassemble individual modules as needed
(pneumatic power module or drive module).
When the spring module is to be removed it should be removed from the drive
module prior to the pneumatic power module removal or disassembly.
The pneumatic power module can be disassembled while still attached to the drive
module or the pneumatic power module can be removed from the drive module
and disassembled separate to the actuator (refer to Section 5 - Module Removal
and Installation).
To ensure correct reassembly; that is, with pneumatic power module or spring
module on same end of drive module as was prior to disassembly, mark or tag
right (or left) and mark mating surfaces.
For spring module removal and installation refer to Section 5, steps 5.3 and 5.4.
