Tube Assembly (Oil Pump Return to Oil
Cooler - Forward).
Install the Tube Assemblies (Forward Reduction Gearbox
Scavenge). Place a new packing (5) in the groove (6) on the
screen (1), place the screen in the gearbox (7), and align the
screw holes in the screen and gearbox.
Then put one new
packing (8) on each tube (2 and 9). Now place the tubes (2)
in place on the engine, line up the tubes (2 and 9) (while
placing the hole in the bracket (10) over the nut (11), and
screw the couplings (12 and 13) together (fig. 1-38).
Put one new packing (14) on each tube (2 and 3), and put a new
packing (15) in the groove of the flange on the tube (3).
Then put the tube (3) in place on the engine, line the tubes
up (2 and 3), and screw the couplings together (16 and 17)
(fig. 1-38).
Install the screws (4) through the tube into the gearbox and
torque them between 100 - 110 inch-pounds. Tighten the tube
couplings (12 and 13, 16 and 17) (fig. 1-38).
