(1) Make sure that the sleeve locking nut (110) is loosened and remove
the two bolts (130) which attach the end fitting (120) to the LPT
frame.
(2) Put the oil supply tube (40) and the damping oil tube (70) in
position.
(3) Connect the damping oil tube (70) to the nipple (90) of the No. 5 bearing support and to the oil supply tube (40). Tighten the coupling nuts by hand.
(4) Connect the oil supply tube (40) to the nipple (50) and to the oil
supply tube (140). Tighten the coupling nuts by hand.
(5) Lubricate the threads of the bolts (130) with graphite grease
(Material No. CP2101).
(6) Attach the end fitting (120) to the LPT frame with bolts (130).
