(a)
Disconnect aileron spring cartridge at spoiler control quadrant lower crank. (See figure 503.)
(b)
Install rigging pin No. A/S-3 in spoiler control quadrant lower crank.
(c)
Install rigging pin No. A/S-4 at aileron bus drum.
(d)
Check that rod end bolt can be inserted freely without deflecting spring cartridge. If bolt does not fit freely: 1) Loosen rod end checknut. 2) Adjust rod end until bolt will fit. 3) Tighten rod end checknut within 10 to 20 pound-inch torque range.
(e)
Connect aileron spring cartridge at spoiler control quadrant lower crank. 1) Ensure that spring cartridge is positioned with drain holes down and antirotation
fork on lower side of lower crank clevis. 2) Install rod end bolt with head up. Secure with spacer, washer, nut and cotter pin.
(f)
Remove rigging pins No. A/S-3 and A/S-4.
(4)
Adjust Spoiler Wing Cables (WSA1, WSA2, WSB1 and WSB2)

NOTE: Cables WSA1 and WSB1 control flight spoilers No. 2 and 7. Cables WSA 2 and WSB2 control flight spoilers No. 3 and 6.
(a)
Set speed brake control lever to DOWN detent and ensure that aileron control system is in neutral.
(b)
Install rigging pin A/S-14 in spoiler mixer and SB-2 in ratio changer. (See figure 503.)
(c)
Check that rigging pins A/S-8 and A/S-9 can be freely inserted in spoiler actuator quadrants on left wing. (See figure 504.)
(d)
Check that rigging pins A/S-10 and A/S-11 can be freely inserted in spoiler actuator quadrants on right wing.
(e)
With rigging pins installed per steps (b), (c) and (d) check that tension in spoiler wing cables WSA1, WSA2, WSB1 and WSB2 is within 15 pounds of required value for ambient temperature. See temperature - tension chart in figure 501 for required cable tension.

(f) If a new spoiler wing cable (WSA1, WSA2, WSB1, WSB2) is installed: 1) Tension cables to twice the value required for ambient temperature. See
temperature - tension chart in figure 501. 2) Remove rigging pins A/S-14, SB-2 and A/S-8 through A/S-11. 3) With speed brake control lever in DOWN position actuate aileron control wheel
through 20 full travel cycles.
NOTE: Spoiler mixer must be installed to cycle spoiler wing cables.
4) With speed brake control lever in UP position actuate aileron control wheel
through 20 full travel cycles. 5) Set speed brake control lever to DOWN position. 6) Reinstall rigging pins A/S-14, SB-2 and A/S-8 through A/S-11.
(g)
If checks in steps (c), (d) or (e) are not met or if step (f) was accomplished use turnbuckles to adjust cable tension within (+10/-0) pounds of required values in temperature - tension chart in figure 501.
(h)
Install turnbuckle locking clips and lockwire adjacent turnbuckles together. (See figure 505.)
(i)
Remove rigging pins A/S-14, SB-2 and A/S-8 through A/S-11.
(5) Adjust Ratio Changer Input Rod
CAUTION: Step (5)(C)5) thru (C)7) is a critical installation step subject to mis-assembly that could result in the linkage disconnecting from the aft aileron control quadrant, affecting safe flight and landing.
(a)
Set speed brake control lever to DOWN position and ensure that aileron control system is in neutral.
(b)
Insert rigging pins A/S-14 in spoiler mixer and SB-2 in ratio changer. (See figure 503.)
(c)
Check that rigging pi n A/S-3 fits freely through rigging pin hole in lower crank at spoiler control quadrant. If rigging pin does not fit freely: 1) Remove bolt to disconnect ratio changer input rod from upper crank at spoiler
control quadrant. 2) Install rigging pin A/S-3. 3) Loosen the checknut on the input rod. 4) Adjust the rod end until you can install the bolt to attach the input rod. 5) Install the bolt with the head up. 6) Install the washer, nut, and cotter pin on the bolt. 7) Tighten the checknut on the input rod.
