A. Installation of the Oil Tank Drain Hose
(1) Remove the protective covers from the oil tank, the drain tube and the drain hose.
(2) Connect the drain hose (25) to the oil tank. Do not torque the coupling nut at this time.
(3) Connect the oil tank drain hose (25) to the drain tube (20). Do not torque the coupling nut at this time.
(4) If removed, attach the tube (20) to the fan case channel with the clamp (5) and the bolt (10).
(5) Make sure that the oil tank drain hose (25) is aligned correctly on the engine.
(6) TORQUE the bolt (10) on the fan case channel to between 20 and 25 lbf.in (0.22 and 0.28 m.daN).
(7) TORQUE the nuts (15) to between 20 and 25 lbf.in (0.22 and 0.28 m.daN).
(8) Torque the hose coupling nuts. CAUTION : USE A SECOND WRENCH TO HOLD THE FITTINGS WHEN YOU
_______ LOOSEN/TIGHTEN THE TUBE COUPLING NUTS. THIS PREVENTS DAMAGE TO THE TUBES.
(a) TORQUE the hose (25) coupling nuts to between 200 and 250 lbf.in
(2.26 and 2.82 m.daN).
