Release the captain's tiller (3) and let it go to the center without manual aid. Make sure the conditions that follow occur:
(a)
The tiller goes to the center in less than 4 seconds.
(b)
The steering collar (41) is less than |1 1/2 degrees from the center.
(c)
If the nose landing gear is more than |1-1/2 degrees from the center, do the steps that follow: 1) Adjust the tension in the cables NWSA and NWSB until the
nose landing gear is less than |1-1/2 degrees from the center (the tension of the cables must be in the limits shown in Table 502).
NOTE: Adjust one cable, then the other, in small
____
increments.
2) Remove the pressure from the left hydraulic system (AMM 29-11-00/201).
3) Put the nose landing gear to a position less than |1/4 degrees from the center. Make sure the rig pins NS1, NS2, NS3, and NS5 have a free fit.
4) Pressurize the left hydraulic system (AMM 29-11-00/201).
(d) If you adjusted the cables with step (a), make sure the rig pins NS1 through NS5 have a free fit. The nose landing gear must be less than |1/4 degree from the center when you do this.
