ADJUST INJECTOR RACK CONTROL LEVER - Continued
When using a torque wrench to obtain desired torque of the lock nut and maintain the
position of the adjusting screw, it will be necessary to use a crowfoot attachment. When
using an adaptor, refer to the Torque Limits work package (WP 0174) for adaptor formula
to calculate the applied torque.
While holding the adjusting screw (Figure 7, Item 1) steady, use a torque wrench and crowfoot adaptor to
torque lock nut (Figure 7, Item 2) to 24 to 35 in. lb (2.7 to 3.9 N·m).
The first soldier returns the throttle arm (Figure 4, Item 1) to the idle position.
On the left cylinder bank (Figure 8, Item 2), install fuel rod (Figure 8, Item 1) into clevis lever
(Figure 8, Item 4) with clevis pin (Figure 8, Item 3) and cotter pin (Figure 8, Item 5).
Figure 8. Left Cylinder Head.
The first soldier slowly moves the throttle control arm (Figure 4, Item 1) to the full fuel position while the
second soldier observes the movement of the fuel rods (Figure 9, Items 2 and 5) in both cylinder banks.
The left and right fuel rods should move smoothly, uniformly and should not bind or bend
when throttle control arm is moved from the idle to the full fuel position. The injector rack
should rotate downward with gentle pressure and return to original position when pressure
Check the drag on both pins (Figure 9, Items 7 and 9) and adjust the number one right until drag is equal
to the number one left.
