Connect the NI throttle control linkage as
outlined in paragraph 2-52.
Installation of T74 NI Controls.
Install the NI control linkage as shown in figure 2-45,
observing the following:
Install the bracket (1) on the engine test dolly
mount ring, using four bolts (2) and four washers (3).
The NI slave unit specified in the
Install the NI slave unit (4) on the bracket (1),
using three bolts (5), three washers (7), and three nuts
Install one nut (8) and one rod end (9) on each
end of the rod (10). Do not tighten the nuts at this time.
Adjust the center-to-center distance between the
holes in the rod ends (9) to 20.25 inches, then tighten
the nuts (8).
Disconnect the aft end of the fuel control unit
control rod (11) from the control lever (12). Reinstall the
attaching parts in the free end of the control rod to
facilitate reinstallation after engine test.
Secure the control rod (11) to a non-moving part
on the engine. Ensure freedom from interference
between the control rod and engine parts or accessories.
Attach one end of the rod (10) (and assembled
parts) to the upper hole in the control lever, using the
bolt (13), spacer (14), washer (15), and nut (16).
h. Position the NI master control unit in the control
cab to align the rod end (9) with the end hole in the
slave unit lever arm.
Attach the other end of the rod (10) to the lever
arm of the slave unit, using the bolt (18), spacer (17),
washer (19), and nut (20).
Position the NI linkage such that the control
lever (12) is at Ground Idle. (The master control unit
lever arm will automatically move to the corresponding
position in the control cab.)
Use a non-destructive pencil, to mark the
Ground Idle position on the master control unit quadrant,
then measure 56 degrees of arc on the quadrant in the
forward (throttle advanced) direction and mark this
