General Disassembly

WARNING: DANGEROUS GAS AND/OR LIQUIDS
It is possible that the actuator may contain a dangerous gas and/or liquids. Ensure that all
proper measures have been taken to prevent exposure or release of these types of
contaminants before commencing any work.

Hydraulic Power Module Disassembly

NOTE:
Review Section 2 steps 2.1.1 through 2.1.5 general disassembly before proceeding with
hydraulic power module disassembly.
WARNING: DISCONNECT OPERATING PRESSURE
If not already removed disconnect all hydraulic pressure from actuator power cylinders.
CAUTION: CONTAIN HYDRAULIC FLIUD
Use some means to contain hydraulic fluid as the tubing (piping) is disconnected from the
hydraulic power cylinder (2-10).

Section 2 - Actuator disassembly is written to either completely disassemble
the entire actuator or can be used to disassemble individual modules as needed
(hydraulic power module or drive module).
When the spring module is to be removed it should be removed from the drive
module prior to the hydraulic power module removal or disassembly.
The hydraulic power module can be disassembled while still attached to the drive
module, or the hydraulic 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 hydraulic power module or spring
module on same end of drive module as was, 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.
