Sliding the torque tube

fuselage hole on the left side.
Sliding the actuation flap of the
inlet lever arm, and the remaining
end mounting bracket
inner tube long torque, and pass the tube end through the other fuselage wall, and the
hook bracket on the other side.. Position the actuating arm on the torque tube assembly
such that it matches the tab of the actuating lever assembly on the center console (not
centered on the console, but aligned to the left side to allow space for the elevator push-
pull rod assembly on the right side). Locate the loose (center) flap hook bracket adjacent
to the actuating arm, and drill the mounting top hole for the mounting medium bracket
(in this location the bracket should be close to the plane’s centerline if the assembly is
good ). This center mounting bracket can be mounted with #10-32 hex head screws since
the surface does not need washing and access will be better for a wrench than a
screwdriver.
Center the actuation tube on the aircraft, and ensure that enough free ends available
at each end for mounting the flap driver arms.. Level the actuation flap arms that are on
the outside of the fuselage, with the ends of the arms facing to the rear. Set the center of
the input drive arm vertical, and drill the flap, actuator arm and tube by two #10-32
screws. Space the screws just enough to provide key access. Locate holes and install
screws so that the head ends will be toward the spar surface when the actuating arm is
vertical, to allow free rotation during flap actuation. With the torque tube mounted, rotate
it several times to clear up any interference and connection, and locate and drill for the
second mounting bolt in each bearing strip. External screws are also flat head #10-32
