o
Next, remove the slack from the middle cable (Item 6).
Set the
adjustment nut (Item 7) so a 1/32-inch gap exists between the
adjusting nut (Item 7) and the actuator block (Item 1) and tighten
the locking nut (Item 8) against the adjusting nut.
o
Remove the slack from the top cable (Item 9) and set the adjustment
nut (Item 10) for a 1/8-inch gap between the adjusting nut and
actuator block.
Tighten the locking nut (Item 11) against the
adjusting nut (Item 10).
o
The last step in actuator cable adjustment is the adjustment to the
handle cable. The handle cable activates the activator cables for
engine AFES cylinder bottle no. 2 and crew AFES cylinder bottles
nos. 3 and 4.
Remove the slack from handle cable (Item 12) and
adjust the cable length for a 1/4 to 1/2-inch gap between the handle
retaining springs (Item 13) and the packing nut (Item 14).
The
actuator assembly end of the cable is now secured to the pin (Item
15) by the tightening of the setscrew (Item 16). Cut off the excess
handle cable (Item 12) length on the inside of the actuator assembly
(Item 2) to within 3/8 to 1/2-inch beyond the pin (Item 15).
o
The fire extinguisher seal (Item 17) may now be installed through
the nut (Item 14) and around the pull handle (Item 18).
The above cable adjustment procedures also apply to the crew AFES removal/
installation procedures.
To conclude the engine AFES cylinder bottle installation procedures, remove
the anti-recoil plugs (Item 9, Figure 14) from the discharge ports of engine
AFES cylinder bottles no. 1 and no. 2.
You can now connect the elbows (Items 10 and 12, Figure 14) and the plug
adapters (Items 3 and 11, Figure 14) to the discharge ports of the engine
compartment cylinder bottle assemblies, remove the locking pin (Item 15,
Figure 14) from the valve actuator guard of engine extinguisher cylinder
bottle no. 2, and reactivate the engine AFES.

Bottles.
The crew AFES T/A panel MAINTenance
switch has been turned to
the vertical position (no power).
After the
MAINTenance switch has been
set to the vertical position, ensure all lights,
including POWER ON light,
on the crew T/A panel goes off.
