TASK 72-00-02-030-802
1 . General.
A.This procedure gives instructions to continue the disassembly of the propulsor. This procedure removes the external configuration hardware. Refer to Figure 501.
B.This procedure starts with the propulsor module assembly (propulsor) (30-020 , 72-00-00) (SIN 0010C) in the horizontal position. The propulsor can be installed in the 11C3044   engine module adapter assembly, attached to the customer overhead rail system, or supported by the 11C3281   pedestals, at the equivalent disassembly status of TASK 72-00-02-030-801 (72-00-02, DISASSEMBLY 001) .
C.Modules that you remove can have external hardware that you will remove at the module disassembly level.
D.Before you do this procedure, read the Assembly and Disassembly Techniques section. Refer to TASK 70-10-00-800-009 (ASSEMBLY AND DISASSEMBLY TECHNIQUES) .
E.Install protective covers/plugs on tubes and hoses to prevent damage and contamination.
F.Make sure that you obey all site safety and environmental controls or personal injury can occur.
