GROUND SPOILER INTERLOCK VALVE CABLE - ADJUSTMENT/TEST
1. General
A. Adjustment and test of the ground spoiler interlock valve cable must be accomplished with the airplane jacked so that the right main gear shock strut is fully extended.
2. Ground Spoiler Interlock Valve Cable Adjustment
A. Equipment and Materials
(1) Rigging Pins Kit - F70207-3, -52, -61, or -84:
REF NO. F70207-( ) DIAMETER (INCHES) LENGTH (INCHES) FUNCTION
S/B-3 -11 0.309-0.311 6.7 +0.25 Ground Spoiler Interlock Valve
B. Adjust Ground Spoiler Interlock Valve Cable.
(1)
Place airplane on jacks so that right main gear oleo is fully extended (Ref Chapter 7, Jacking).
(2)
Check that rigging pin S/B-3 can be freely installed through interlock valve lever (Fig. 501). If rigging pin does not fit freely:
(a)
Remove bolt attaching lower rod end to landing gear torsion link.
(b)
Remove clamp from protective boot and slide boot clear of rod end.
(c)
Insert rigging pin S/B-3. Loosen check-nut and adjust lower rod end so bolt fits freely.
(d)
Ensure that threads are visible in rod end inspection hole.
(e)
Install bolt attaching rod end to landing gear torsion link. Secure bolt with washer, radius filler, nut and cotter pin.
(f)
Ensure that both upper and lower rod ends properly align and tighten check-nut on lower rod end.
(g)
Check that rigging pin S/B-3 fits freely.
(3)
Remove rigging pin S/B-3.
(4)
Check that swivel tube is visible through inspection hole in guide tube.
(5)
Position protective boot on spacer. Secure with clamp with worm screw aft and thumb flats outboard for maximum clearance.
(6)
Test valve cable.
(7)
Remove jacks from airplane (Ref Chapter 7, Jacking).

3. Ground Spoiler Interlock Valve Cable Test
A. Prepare Ground Spoiler Interlock Valve Cable for Tests.
(1)
Place airplane on jacks so that main gear oleo is fully extended (Ref Chapter 7, Jacking).
(2)
Provide electrical power.
(3)
Provide system A hydraulic power (Ref 27-62-0).
B. Test Ground Spoiler Interconnect Valve Cable
(1)
Move speed brake control lever to the UP position.
(2)
Check that ground spoiler panels show no sign of movement.
(3)
Release all air pressure in right main gear shock strut.
(4)
Place jack under jack pad on right main gear axle (Ref Chapter 7, Jacking).
CAUTION: DO NOT JACK AT ANY POINT OTHER THAN JACK PAD.
(5)
Slowly raise axle jack to compress right main gear shock strut until ground spoiler interlock valve opens. Check that fround spoiler panels move to full up.
(6)
Check that distance shock strut inner cylinder is compressed from the fully extended condition is 1.5 +1.5/-0.0 inches.
(7)
Place speed brake control lever in DOWN position. Check that ground spoiler panels retract.
(8)
Lower axle jack and allow right main gear shock strut to fully extend. Remove axle jack.
(9)
Check that ground spoiler panels are full down.
C. Restore Airplane to Normal Configuration
(1)
Remove system A hydraulic power (Ref 27-62-0).
(2)
Remove electrical power if no longer required.
(3)
Service right main gear shock strut (Ref Chapter 12, Main Landing Gear Shock Strut -SRV).
(4)
Lower and remove jacks (Ref Chapter 7, Jacking).
