C. Adjust Elevator and Tab Control System
(1) Adjust elevator control cables EA and EB and pitch force transducers.
(a)
Set horizontal stabilizer B dimension at 41.57 士0.05 inches, using trammel bar (Fig. 502).
(b)
Remove elevator systems A and B hydraulic power (Ref 27-31-0 MP).
(c)
Ensure that mach trim actuator is in null position (Ref 27-31-0 MP).
(d)
Insert rigging pin E-5 in elevator right aft quadrant and ensure that rigging pin is easily movable. If holes do not align, move elevator surface by hand, up or down, until they align. Elevator surface should stay in this position.
(e)
Insert rigging pin E-1 in elevator left forward quadrant. Check that Rigging pin fits easily.
(f)
Remove shoulder bolt from both column quadrants and check that rigging pins E-2 and E-3 fit easily through shoulder bolt installation holes. See Fig. 503 for locations.
(g)
Check that tension in cables EAR, EBR, EAL, and EBL is within value required for ambient temperature per table on Fig. 501.
(h)
If new cables are installed:

1) Adjust turnbuckles on the EA and EB cables to 300 士20 pounds to prestretch
cables.
2) Adjust all seals during rigging to eliminate bending of cables.
3) Remove rigging pins E-1 and E-5.
4) Cycle control column 25 times through full travel.
5) Accomplish steps (d) thru (g).
(i)
If the conditions of steps (d), (e), (f), or (g) are not met or if step (h) was accomplished, remove bolts from adjustable ends of pitch force transducer and use turnbuckles to adjust cable tension to value for ambient temperature per table on Fig.
501.
(j)
Rigging pins E-1, E-2, E-3, and E-5 must all be easily movable after final adjustment.
(k)
If steps (h) or (i) were accomplished, adjust and connect pitch force transducers per Chapter 22, Pitch Control Wheel Steering Force Transducer - A/T.
(l)
Remove rigging pins E-2 and E-3 and install shoulder bolts.
(m)
Install locking clips on all turnbuckles.
(n)
Remove rigging pins E-1 and E-5.
