A. Inspect each seal ring assembly (30) to be installed for damage.
Subtask 73-11-40-420-054
B. Installation of the fuel nozzle:
NOTE : The fuel nozzles are given position numbers in a clockwise (CW)
____ sequence when you look at them from the aft of the engine. Position number 1 is at 12 o'clock.
(1) Remove the protective caps from the nozzles, fuel lines and combustion case pads.
R (2) Apply a thin layer of vaseline (Material No. CP5070) on the O-ring R (140) for the drain shroud and on the O-ring (150) for the fuel R nozzle.

(3) Install the new o-ring (140) on the drain shroud.
(4) Install the new o-ring (150) on the nozzle.
(5) Apply a thin layer of vaseline (Material No. CP5070) to the tip of the fuel nozzle.
(6) Install the seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40), seal (40) into the seal ring assembly (30) on the and flange of the fuel nozzle. Align the holes in the flange of the seal ring assembly (30) with the holes in the flange of the nozzle.
R
R (7) Installation of the nozzle.
CAUTION : DO NOT USE FORCE TO INSTALL THE NOZZLE IN THE COMBUSTION
_______ CASE. YOU MAY CAUSE DAMAGE TO THE COMBUSTION CHAMBER INNER OR OUTER FERRULES OR TO THE TIP OF THE NOZZLE.
NOTE : Install standard flow, wide spray angle fuel nozzles in
____ positions 7, 8, 14 and 15 above and below the igniter plugs. These nozzles should have a natural band color.
(a) Put the nozzle into the combustion case pad with the tip forward.
(b) Turn the nozzle counterclockwise while you push it down onto the combustion case pad.
R (8) Move the nozzle aft to engage the tip of the nozzle in the combustor swirl cup.
R (9) Apply a thin layer of graphite grease (Material No. CP2101) or Never Seez, Pure Nickel, Special (Material No. CP2619) to the threads and friction surfaces of the bolts (10) and (50) that attach the nozzles to the combustion case.
R (10) Move the hinge bracket (20) into the correct position, if necessary.
R (11) Put the brackets (60), (70), (80), (90), (100), (110), (800) into position on top of the fuel nozzle, if necessary.

R (12) Install the bolts to attach the fuel nozzle, seal ring assembly (30) and brackets (20), (60), (70), (80), (90), (100), (110), as necessary, to the combustion case.
NOTE : Make sure you use the correct length bolts (10) at positions____ where there are brackets and that the brackets are installed in the correct position on top of the fuel nozzle.
R (13) TORQUE the bolts (10) and (50) to between 110 and 120 lbf.in (1.24 and 1.35 m.daN).
R (14) Wirelock the bolts (10, 50) with lockwire 0.032 in. (0.8 mm) dia (Material No. CP8001) or lockwire 0.032 in. (0.8 mm) dia (Material No. CP8002).
R (15) Apply a small amount of fuel system preventative (Material No. CP5066) on the nut to ferrule interface surfaces of the fuel nozzle, fuel supply tube, and drain tube.
R (16) Connect the fuel supply tube to the nozzle. TORQUE the coupling nut to between 120 and 135 lbf.in (1.35 and 1.52 m.daN).
R (17) Wirelock the fuel tube coupling nut to the tab on the nozzle with lockwire 0.032 in. (0.8 mm) dia (Material No. CP8001) or lockwire 0.032 in. (0.8 mm) dia (Material No. CP8002).
R (18) Connect the drain shroud to the nozzle. Tighten the drain shroud using soft-jawed connector pliers until the shroud nut bottoms out.
NOTE : When the shroud nut is bottomed out, no more than two full____ threads should be exposed on the fuel nozzle.
R (19) Connect the drain tube to the fuel nozzle drain shroud. TORQUE the coupling nut to between 135 and 150 lbf.in (1.52 and 1.69 m.daN).
