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.

NOTE:
For field configuration only. SB 75-0011 removes the tube (01-040, 75-11-30) (SIN 63708) but keeps the connection with the tube (01-030A, 75-11-30) (SIN 63703) open. SB 75-0027 repairs this with the installation of the cap. This procedure removes this cap.
NOTE:

P.Remove the upper and lower exhaust gas temperature (EGT) harnesses from the propulsor. Refer to Figure 520 and do as follows:
CAUTION:
DO NOT APPLY SIDE-LOADS TO THE THERMOCOUPLE CABLE PIGTAIL LEADS WHEN YOU REMOVE THEM. THE EGT THERMOCOUPLE PROBE STUDS CAN RESULT IN DAMAGE.
CAUTION:
BEFORE YOU REMOVE THE THERMOCOUPLE HARNESS CONNECTOR NUTS FROM THE EGT PROBE, PUT A SMALL AMOUNT OF PENETRATING OIL ON THE ENDS OF THE EGT PROBE STUDS AND ON THE THREADS OF THE HARNESS CONNECTOR NUTS, OR THE EGT PROBE STUDS CAN RESULT IN DAMAGE.
(1)Apply a small amount of C02-053  penetrating oil at the ends of the EGT probe studs and on the threads of the harness connector nut.
(2)Remove the upper EGT harness (upper harness) as follows:
(a)Remove the upper harness nuts from the EGT probes.
(b)Remove the bolts that attach the upper harness to the support bracket on the LPT supply air duct.
(c)Remove the bolts that attach the tabs on the upper harness to the support brackets.
(d)Remove the upper harness.
WARNING:
REFER TO THE PRODUCT LABEL AND THE MANUFACTURER’S (MATERIAL) SAFETY DATA SHEET (SDS) FOR INSTRUCTIONS ON THE HAZARDS, STORAGE, SAFE HANDLING AND PROPER USE OF THIS PRODUCT.
(3)Clean the threaded surfaces that received penetrating oil with a cotton swab or brush soaked with C04-035  isopropyl alcohol and let them air-dry before re-assembly.
NOTE:
The EGT probe has two different stud diameters for the thermocouple lead connectors. The thermocouple cable lead connector nuts are captive nuts and part of the thermocouple cable leads.
(4)Do Subtask 72-00-02-030-578 (paragraph 3.Q.(1) thru paragraph 3.Q.(3)) again for the lower EGT harness (lower harness).
