(12)
Measure the clearance between the spoilers No. 9 thru 12 and the trailing edge flaps (Fig. 504):
(a)
Make sure the clearance at the nearest point between the spoilers No. 9 thru 12 and the trailing edge flaps is 0.02-0.16 inch(.508-4.06mm) (Section A-A). There is no specified maximum clearance.
S 835-119
(13) Adjust the clearance between the spoilers and the flaps if it is not in the tolerance.
WARNING: DO NOT PUT A PART OF YOUR BODY BETWEEN THE SPOILER AND THE
_______ WING UNLESS THE SPOILER ACTUATOR IS LOCKED OR THE HYDRAULIC POWER IS RELEASED. THIS CAN CAUSE INJURY TO PERSONS.
(a) Open the applicable trailing edge panel and extend the flaps, or lift the spoilers to get access to the spoiler control package. 1) If you lifted the spoilers, install the spoiler actuator
locking tools or do this task: "Remove Hydraulic Power" (AMM 29-11-00/201).
CAUTION: LOOSEN THE CHECKNUT SUFFICIENTLY TO MOVE THE TAB ON THE
_______ LOCKING DEVICE OUT OF THE SLOT IN THE PISTON ROD. YOU CAN BREAK THE TAB FROM THE LOCKING DEVICE.
(b) Loosen the checknut on the piston rod end.

MAINTENANCE MANUAL
CAUTION: DO NOT TURN THE PISTON ROD IF THE CONTROL PACKAGE IS
_______ PRESSURIZED. YOU CAN CAUSE DAMAGE TO THE INTERNAL SEALS.
(c) Turn the piston rod to adjust the clearance between the spoiler and the flap.
NOTE: Each 1/4 turn of the piston rod will change the
____ clearance between the spoiler and the flap by approximately 0.14 inch.(3.56mm) If you turn the piston rod to change the clearance by 0.35 (8.89mm) or more, you must measure the clearances again.
CAUTION: MAKE SURE THE PISTON ROD IS FULL OF THE CORROSION
_______ PREVENTIVE COMPOUND. IF IT IS NOT FULL OF THE CORROSION PREVENTIVE COMPOUND, THERE WILL BE CORROSION.
(d) Fill the rod end with the corrosion preventive compound before the adjustment if it is necessary: 1) Fill the piston rod if you removed the rod end from the control package. 2) Fill the piston rod if you moved the rod end out of the piston 0.50 inch or more. 3) Remove the rod end from the spoiler and the control
package. 4) Fill the piston rod with the corrosion preventive compound. 5) Install the rod end.
(e)
Engage the locking device with the piston rod.
(f)
Apply a layer of the corrosion preventive compound to the external threads.
(g)
Tighten the checknut hand tight.
(h)
Remove the spoiler actuator locking tools, if it is necessary.
(i)
Do this task: "Supply Hydraulic Power" (AMM 29-11-00/201).
(j)
Put the speed brake lever in the DOWN position to lower the spoilers until the control package piston is fully retracted.
(k)
Make sure the clearance between the spoiler and the flap is in the tolerance shown in Fig. 504, Sections A-A and B-B. There is no specified maximum clearance. 1) If the clearance is not in the tolerance, loosen the
checknut and adjust the spoiler again.
(l)
If the clearance is in the tolerance, tighten the checknut: 1) Tighten the checknut to 1200-1300 pound-inches (135.6-146.9Nm) for spoilers No. 1 thru 4 and 9 thru 12. 2) Tighten the checknut to 2150-2350 pound-inches (242.9-265.5Nm) for spoilers No. 5 and 8. 3) Loosen the checknut and make sure the parts of the locking mechanism stay engaged correctly.
4) Tighten the checknut to 1200-1300 pound-inches (135.6-146.9Nm) for spoilers No. 1 thru 4 and 9 thru 12.
