o The actuator assembly.
o The pull handle cable.
o Fire extinguisher activator cables for engine fire extinguisher no.
2 and crew fire extinguishers no. 3 and no. 4.
The removal of components will be addressed in the order shown above. The
reverse procedure of removal will be used for installation of the removed
AFES MDS components.
As you have learned earlier in the subcourse, the AFES must be deactivated
before attempting any maintenance or repair of the system. Refer to Part C
of this subcourse for the procedures used to deactivate/reactivate the AFES.
With the deactivation process accomplished, you can now begin the removal
process of the AFES MDS actuator assembly. Use Figure 38 and the following
removal procedures to accomplish this task.
o Remove the four screws (Item 7), four lockwashers (Item 8), and the
four flat washers which secure the cover (Item 6) to the actuator
assembly (Item 15) and remove the cover assembly.
Discard the
removed lockwashers.
o Now loosen (do not remove) the socket head screw (Item 1) which
secures the pull handle cable assembly (Item 3) to the cable pin
assembly (Item 16) and remove the pull handle cable assembly from
the cable pin.
NOTE:
As cables are removed, be sure they are tagged to ensure proper
identification during installation.
o Now proceed to remove the locknuts (Item 5) and the nuts (Item 4)
which secure each of the three cylinder cables (Item 10) to the
cable block (Item 14). Discard the removed lockwashers.
o You may now remove the threaded fittings (Item 2) which hold the
handle cable and the three cylinder cables onto the actuator
assembly (Item 15). Withdraw the cables from the actuator assembly.
Remember to tag each cable as you remove it for proper
identification.
