Add an M3 Jackscrew to Housing Adapter (6-10)
NOTE:
This section can also be used to add an M3 to the cylinder end cap (4-20) at the same
time as the M3 is added to the housing adapter (6-10). When a M3 is only being installed
into housing adapter (6-10), skip step 3.3.14 during installation. For single M3 addition to
cylinder end cap (4-20), use Section 5.6.
5.5.1
Prior to disassembly, review all of Section 1 Introduction.
5.5.2
Disassemble the actuator per Section 2.1 - General Disassembly, Section 2.2
- Pneumatic Cylinder Disassembly steps 2.2.2 through 2.2.5 and Section 2.3 -
Housing Disassembly steps 2.3.2 and 2.3.3.
5.5.3
Prior to actuator reassembly, review all of Section 3.1 - General Reassembly, 3.2 -
Housing Reassembly and 3.3 - Pneumatic Cylinder Reassembly.
5.5.4
If new M3 housing adapter (6-10) is not pre assembled with the M3, then assemble
M3 to the housing adapter (6-10) per Section 3.2 step 3.2.1.
WARNING: M3 INSTALLATION LIMITATIONS
The M3 cannot be installed on a standard CBA actuator unless the M3 targets are installed
on the piston assembly as shown in Figure Number 2. If the M3 is operated with a piston
that does not have a target, the groove pin (12-20) is subject to failure.
5.5.5
Add the M3 targets to the piston assembly (4-50) per Figure Number 2 - M3 piston
targets.
