(f)  
Rotate captain's control wheel counterclockwise 50 ±5 degrees and return toward neutral.

(g)  
Check that spoiler is fully retracted when captain's control wheel is 4 ±2 degrees counterclockwise from neutral. Turn captain's control wheel clockwise 5 degrees from neutral to ensure that actuator pistons are bottomed. Check that spoilers do not move. Check that spoiler-to-flap clearance remains at 0.03 + 0.10/-0.00 inch.

(h)  
Repeat steps (b) thru (g) for flight spoiler No. 3.

(i)  
If check in steps (g) or (h) are not within limits: 1) Lower flaps by placing flap control lever in FLAP DOWN detent. 2) Hold captain's control wheel at 9 ±1 degrees counterclockwise from neutral. 3) Break lockwire on input arm adjusting screw and loosen checknut (Fig. 504).

4) Using adjusting screw, set No. 2 and 3 actuators so that spoiler panels begin to
rise from zero (fully retracted) position.
5)  Raise flaps by placing flap control lever in FLAP UP detent.
6)  Release captain's control wheel and repeat steps (f) and (g).
7)  Tighten checknut on input lever adjusting screw 30 to 40 pound-inches and
install lockwire.
(j)  
Turn captain's control wheel counterclockwise from neutral to ensure that flight spoilers No. 6 and 7 are fully retracted.

(k)  
Install control surface protractor stand and protractor on flight spoiler No. 7. Set protractor to zero.

NOTE: Protractor may be hand-held on spoiler instead of using stand.

(l)  
Rotate captain's control wheel clockwise 50 ± 5 degrees and return toward neutral.

(m)  
Check that spoiler is fully retracted when captain's control wheel is 4 ± 2 degrees clockwise from neutral. Turn captain's control wheel counterclockwise 5 degrees from neutral to ensure that actuator pistons are bottomed. Check that spoilers do not move. Check that spoiler-to-flap clearance remains at 0.03 + 0.10/0.00 inch.

(n)  
Repeat steps (j) thru (m) for flight spoiler No. 6

(o)  
If check in steps (m) or (n) are not within limits: 1) Lower flaps by placing flap control lever in FLAP DOWN detent. 2) Hold captain's control wheel at 9 ± 1 degrees clockwise from neutral. 3) Break lockwire on input lever adjusting screw and loosen checknut. 4) Using adjusting screw, set No. 6 and 7 actuators so that spoiler panels begin to

rise from zero (fully retracted) position.
5) Raise flaps by placing flap control lever in FLAP UP detent.

6) Release captain's control wheel and repeat steps (l) and (m). 7) Tighten checknut on input lever adjusting screw 30 to 40 pound-inches. Install lockwire.
(p)  
Move speed brake control lever until flight spoilers No. 2, 3, 6, and 7 rise 15 ± 1 degrees measured by protractors positioned on spoilers. Any one spoiler panel shall not vary from position of the other three by more than 1/2 degree. If not within limits, repeat step (i).

(q)  
Remove protractors and protractor stands from spoilers.

(8)  Adjust Spoiler Mixer (Optional)
NOTE: This check is optional, and need be performed only if spoiler full up and down travel responses at zero speed brakes per par. 3.D.(1) are not met.
(a)  
Open grease fitting access covers on aft surface of spoiler mixer (Fig. 503).

(b)  
Set speed brake control lever in DOWN position.

(c)  
Rotate captain's control wheel counterclockwise 87 degrees from neutral.

(d)  
Check that left cam follower is on maximum rise portion of spoiler mixer cam (viewed through left grease fitting access hole).

(e)  
Return captain's control wheel to neutral.

(f)  
Rotate captain's control wheel clockwise 87 degrees from neutral.

(g)  
Check that right cam follower is on maximum rise portion of spoiler mixer cam (viewed through right grease fitting access hole).

(h)  
Return captain's control wheel to neutral.

(i)  
If checks in steps (d) and (g) are not met use turnbuckles to adjust SBA and SBB cables (Fig. 507). 1) Shorten SBB cable by one-half turn and lengthen SBA cable by one-half turn.

NOTE:  SBB cable is the lower cable on speed brake quadrant on ratio changer. Speed brake quadrant rotates clockwise (looking forward) when tightening SBB cable.
