ADJUST INJECTOR RACK CONTROL LEVER - Continued
Verify the adjustment of the control lever (Figure 5, Item 5) is not too tight.
The first engineer returns the throttle control arm (Figure 4, Item 1) to idle position.
The second engineer observes the injector control rack (Figure 5, Item 4).
If the injector rack reaches the limit of its downward rotation before the throttle arm is
at full fuel position, the adjustment is too tight.
The first engineer slowly moves the throttle arm (Figure 4, Item 1) from idle to full fuel position.
Loosen lock nut (Figure 5, Item 1).
Loosen adjusting screw (Figure 5, Item 2) slightly.
Tighten lock nut (Figure 5, Item 1) and verify adjustment again. Repeat this step until adjustment
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 hold the adjusting screw (Figure 5, Item 2) steady, use a torque wrench and crowfoot attachment to
torque lock nut (Figure 5, Item 1) to 24 to 35 in. lb (2.7 to 3.9 Nm).
On the left cylinder bank (Figure 6, Item 2), remove the cotter pin (Figure 6, Item 5) and clevis pin
(Figure 6, Item 3).
