(11) Filling instructions for the Shimmy Damper
(a) Install the NLG Strut Assy vertically in the Tool P/N 58986A0000–01 Assembly rig.
(b) Apply the silicon oil (AK500000) to the Tool P/N 59502A0000–01 filler. Make sure that there is no
locked air in the filler.
(c) Install the filler to the lower filling port of the steering cuff (2–80).
(d) Apply 0.4–0.5 MPa (52–72.5 psi) compressed air to the filler.
(e) Fill the complete silicon oil volume of the filler to the lower filling port.
(f) Install the hexagon head bolt (1–720) and the washer (1–730) to the bleeding port. Torque
the hexagon head bolt (1–720) to 2 +1 Nm (1.47 +0.74 lbf.ft).

Depending on your company procedures etc you would have to get Agusta and local regulator approval to carry out this procedure as a maintenance task.
