NOTE : At some positions, manifold hinge brackets or engine plumbing
____ brackets are installed with the fuel nozzle. It is necessary to remove these brackets for removal of the fuel nozzle. Identify the bolts and brackets by position number and keep the bolts and the brackets for each nozzle position together to ease the installation of the fuel nozzle.
(2) Cut and remove the lockwire from the bolts (10, 50) that attach the fuel nozzle(s) to be removed to the combustion case.
(3) Apply a small amount of liquid wrench (Material No. CP2162) to the bolts (10), (50) that attach the fuel nozzle(s) to be removed to the combustion case. Permit the Liquid Wrench to soak for approximately 5 minutes.
(4) Put a container 1 l (0.25 USgal) below the fuel nozzle(s) to be removed to catch any fuel leakage.
(5) To remove the fuel nozzles, start at the steps shown on the following reference table:
