CAUTION : USE 2 WRENCHES TO REMOVE OR INSTALL THE TUBE COUPLING
_______ NUTS. ONE WRENCH TO HOLD THE UNION AND ONE TO LOOSEN OR TIGHTEN THE COUPLING NUT. THIS WILL PREVENT DAMAGE TO THE HARDWARE.
 1 Install the PCR line to the PCR port. Torque coupling nut to
_ between 180 and 200 lbf.in (2.03 and 2.26 m.daN).
 (k) Do a wet motoring check for 5 seconds (Ref. TASK 71-00-00-710-002) or until you see sprayed preservation fluid coming out of the engine exhaust nozzle. Move the ENG MASTER control switch to OFF and motor for 2 minutes.
 NOTE : A minimum of 20 quarts (19 liters) of oil mixture is
____ required for preservation motoring.
 (l) Stop the engine motoring. Let the engine coast down.

 (m) Turn the fan rotor:

 WARNING : DO NOT TURN THE FAN ROTOR BY HAND UNLESS YOU ARE
_______ WEARING HEAVY PROTECTIVE GLOVES. MAKE SURE YOU WILL NOT SLIP WHEN YOU TURN THE FAN ROTOR. INJURY TO PERSONS CAN BE CAUSED.
 1 Pull the fan rotor through a minimum of 2 complete turns if it
_
 did not turn during motoring.

 (n) Remove the temporary oil supply line from the fuel pump inlet tube.

 (o) Make sure that the gasket is clean and serviceable (Ref. TASK 70-21-00-918-002).

 (p) Install the 4 washers, and the 4 bolts which attach the fuel inlet tube to the fuel manifold duct.

 (q) TORQUE the bolts to between 65 and 85 lbf.in (0.73 and 0.96 m.daN).

 (r) Ensure VBV doors are closed (Ref. TASK 75-31-20-820-001).

 (s) Install vapor barrier film (Material No. CP2160) on all open areas.

 (t) Install caps or plugs on all open engine areas, such as struts, pipes and accessory pads.

 (u) Put desiccant bags (Material No. CP2098) on either side of the engine. Do not permit the desiccant to touch the engine surfaces.

 NOTE : Replace the desiccant at regular times based on
____ atmospheric and weather conditions. Put the desiccant in the engine so that it will give adequate protection. Install it so that you will have to move a minimum amount of engine protective covers.
 (v) Put COVER - FITTED BARE QEC'D ENGINE SHIPPING (856A2930G01/GO2) over all of the engine. Make sure it is tight.

 (w) Put a tag on the engine to show the engine has been preserved.

 (2) Non-operable Engine Preservation.
 (a) Drain the fuel system as follows. Collect the fuel in a satisfactory container.
 1 Disconnect the filter upstream (inlet) pressure sensing tube
_ from the fuel filter housing (this is the lower sensing tube connected to the fuel filter differential pressure switch at its other end). Let the fuel to drain from the disconnected port.
 2 Disconnect the fuel supply line. Install a cap on the fuel
_
 pump inlet tube.

 3 Remove the fuel filter drain plug. Let the fuel to drain from
_
 the filter.

 4 Remove the fuel pump drain plug. Let the fuel drain from the
_
 pump.

 5 Remove the fuel filter element. Discard the element (Ref. TASK
_
 73-11-10-000-003).

 (b) Preserve the engine as follows:
 CAUTION : DO NOT USE SILICONE BASE OILS IN THE FUEL SYSTEM.
_______ DAMAGE TO THE ENGINE CAN BE CAUSED.

 F EEFF : ALL E E ECES Remove the PBP port plug from the fuel pump. Connect an oilpressurizing cart that contains fuel system corrosion preventive oil (Material No. CP5066) to the boost discharge pressure (PBP) port on the fuel pump. TORQUE the connector to between 45 and 55 lbf.in (0.50 and 0.62 m.daN)

Pump filtered (10 micron) oil into the fuel pump until it flows out of the fuel filter inlet pressure port and filter housing. Continue to pump the oil into the fuel pump until the oil that flows out does not have fuel mixed with it.
Connect the tube to the fuel filter inlet pressure port. TORQUE the coupling nut to between 45 and 55 lbf.in (0.50 and
 0.62 m.daN).
Install a new fuel filter element. Install the bowl cover and drain plug. TORQUE the drain plug to between 45 and 55 lbf.in
 (0.50 and 0.62 m.daN).
Remove the fuel pump discharge (PHP) port plug.
Pump filtered (10 micron) oil into the PBP port until it flows out of the PHP port. Continue to pump the oil into the PBP port until the oil that flows out does not have fuel mixed with it.
