A. Installation of the Oil Tank Drain Tube and Hose.
(1) Remove the protective covers from the manifold module, the oil tank, the drain tube, and the drain hose.
(2) Connect the oil tank drain hose (25) to the oil tank. Do not torque the coupling at this time.
(3) Connect the oil tank drain tube (30) to the hose (25) and the manifold module. Do not torque the coupling at this time.
(4) Attach the tube (30) to the top fan case bracket with the clamp (5), the screw (10), and the washer (15).
(5) Attach the tube (30) to the lower fan case bracket with the clamp (5), the screw (10), the washer (15), and the nut (20).
(6) Attach the tube (30) to the fan case drain tube (35) with the clamp (5), the screw (10), the washer (15), and the nut (20).
(7) Make sure that the oil tank hose (25) and the oil tank drain tube (30) are aligned correctly on the engine.
(8) TORQUE the nuts (20) to between 25 and 20 lbf.in (0.28 and 0.23 m.daN )
.
(9) TORQUE all the couplings to between 250 and 200 lbf.in (2.83 and 2.26 m.daN ).
