8. Check the full travel of the control wheel with relation to the full travel of the stabilator to determine
that the stabilator contacts its stops before the control wheel contacts its stops. With the control wheel in the fore
and aft positions, the travel distance from the point where the stabilator contacts its stops and the control wheel
contacts its stops should approximately equal. Readjust turnbuckles if incorrect.
9. Reinstall access panels.
d. Remove airplane from jacks.

section of the airplane.
b. If the aft trim cable (12) is not to be removed, block the cables at the pulleys (13) in the upper aft section
of the fuselage to prevent them from unwrapping from the trim drum. (Refer to Figure 5-7.)
c. Loosen the cables if the trim control wheel (1) is to be removed or disconnect if the cables are also to be
removed. Do this at the trim cable turnbuckles (10 and 11) in the aft section of the fuselage.

1. Remove the control wheel cover by removing the cover attaching screws.

that secures the wheel between the brackets. Draw the wheel from the brackets. Use caution not to damage trim
indicator wire (2).
3. Unwrap the left cable (9) from the drum.
4. The wheel and drum are joined by a push fit, separate these two items with their center bushing and
unwrap the right cable (8).
5. Tie the cables forward to prevent them from slipping back into the floor tunnel.
e. The trim control cables (8 and 9) may be removed by the following procedure:
1. Remove the front seats, if desired.
2. Unfasten the carpet from the aft portion of the floor tunnel and lay it forward.
3. Remove the tunnel cover located between the trim control wheel and the spar cover by removing
attaching screws.
4. Remove the cable pulleys (6) located in the tunnel by removing the cotter pin, washer and clevis pin (5).
5. Remove the cable rub blocks (37) located on the aft side of the main spar by removing the block
attaching screws.
6. Remove the cable guard pin (36) at the pulley cluster (34) located just aft of the wing flap torque tube at
station 127.25.
7. If installed, remove the cable pulleys (33) within the aft section of the fuselage at station 156.5 by
removing nut, washer, bushing and bolt.
