3 . Procedure.
Subtask 72-00-01-420-001
A.Prepare the fan stator module (00103). Refer to Figure 403 and as follows:
(1)If the fan stator module is installed on the 11C3004   shipping stand, transfer it to the 11C4490   fan case separation dolly as follows:
(a)Before the fan stator module removal, make sure that the 11C3004   shipping stand is in the pallet vertical (engine horizontal) orientation.
(b)If necessary, remove the safety pins for the shipping braces to be removed from the center support and main base. Return the shipping braces to their storage location on the 11C3004   shipping stand.
(c)If installed, remove the fan stator module cover.
(d)Shift the “C” valve handle to the “UP” position to fully raise the center support. Once the center support is fully raised, shift the “C” valve to the “OFF” position.
(e)Remove the safety pins to disconnect the four turnbuckle braces between the OGV support ring and the center support.
(f)Remove the locking pin from the fan mounting plate and rotate the fan stator module to the designated “LOAD” position. Install the locking pin again.
(g)Identify the two cut-outs in the fan mounting ring at the 3:00 o'clock and 9 o'clock positions. The 11C4490   fan case separation dolly will be installed at these locations. Remove any fasteners between the fan case and the fan mounting ring with the span of these cut-outs only.
(h)Slide the 11C4490   fan case separation dolly up to the fan case so that their brackets with holes are on the AFT side of the fan case flange.
(i)Adjust the jacklegs on the 11C4490   fan case separation dolly as necessary to achieve hole alignment.
(j)Attach the 11C4490   fan case separation dolly to the fan stator case. Refer to Figure 401 and as follows:
1Use the jacking caster legs of the 11C4490   fan case separation dolly to align the support bracket of the 11C4490   fan case separation dolly with the fan stator case flanges.
2Attach the left and right support brackets to the forward and aft flanges of the fan stator module.
(k)Make sure that the 11C4490   fan case separation dolly supports the weight of the fan stator module.
(l)Remove the fasteners that hold the fan stator module to the fan mounting ring.
(m)Pull the fan stator module forward or push the 11C3004   shipping stand aft to slowly separate the fan stator module from the 11C3004   shipping stand.
(2)Put an 11C4514   fan case protective mat in the lower fan case area at the 6:00 o'clock location to prevent damage to the inside surfaces of the fan stator module. Refer to Figure 404.
CAUTION:
DO NOT SCRATCH THE ACOUSTIC PANELS OR THE FAN CASE ABRADABLE SURFACE. DAMAGE TO THE PARTS CAN OCCUR.
(3)Install the 11C3331   protectors, if they are not installed. This will protect the forward edge of the acoustic panels. Refer to Figure 403.
WARNING:
ISOPROPYL ALCOHOL IS TOXIC AND FLAMMABLE. USE PERSONAL PROTECTION EQUIPMENT. USE IN A WELL-VENTILATED AREA.
(4)Clean the forward and aft flanges of the fan hub module, and the fan stator module, with C04-035  isopropyl alcohol. Refer to Figure 405.
(5)Remove any tape that is around the fan hub module.
(6)Make sure that all nut plates are installed on the fan hub module.
(7)If not installed, install the 11C4593   surface cooler cover.

(4)Slowly push the propulsor into the fan stator module as follows:
(a)Use visual indicators to make sure that the propulsor and fan stator module are in close alignment. Make adjustments as necessary to attach the two modules correctly.
(b)Make sure that the OGV boltholes are aligned with the boltholes in the aft flange of the fan hub frame.
(c)Make sure that all tools or foreign objects are removed from inside the fan case. Make sure that the drain lines at the 12:00 o'clock position are clear of the mating flanges.
(d)Push the modules together until the bolts (30-070 , 72-00-00) (SIN 84021) can be started into the fan hub frame flanges by hand a minimum of 0.25 inch (6.4 mm) before wrenches are used.
(e)Temporarily install several bolts (30-070 , 72-00-00) (SIN 84021) to hold the flanges together. They will be removed and install again in a later step.

(8)Make sure that the booster acoustic panel leading edge has a step of not more than 0.005 inches (0.127 mm) above the splitter. Refer to Figure 409 (sheet 8 through sheet 12) and do as follows:
(a)Arrange a gauge block/slip gauge that is 0.005 inches |(0.127 mm) on the surface of the booster splitter upstream of the leading edge of the inner acoustic liner. Slide another gauge block/slip gauge of 0.01 inches (0.25 mm) in thickness or more above the 0.005 inches (0.127 mm) gauge block/slip gauge towards the inner acoustic liner. If the gauge block/slip gauge of 0.01 inches (0.25 mm) faces resistance at the leading edge of the acoustic liner, then the step is more than 0.005 inches (0.127 mm). If the gauge block/slip gauge of 0.01 inches (0.25 mm) crosses the leading edge of the acoustic liner, then the step is equal or less than 0.005 inches (0.127 mm). Refer to Figure 409 (sheet 10).
(b)If the step is more than 0.005 inches (0.127 mm), do the steps to remove and install the booster inner acoustic liners again.
(c)Do this step measurement at least at three locations between the bolts and at all 4 bolt locations for each inner acoustic liner. Refer to Figure 409 (sheet 11 and sheet 12).
NOTE:
Step measurement is not required if the inner acoustic liner leading edge is seated below the booster splitter. This condition is acceptable.

Q.A.Alternative Procedure. Install the fan platforms (20-120 , 72-00-00) (SIN 83005) or (20-121 , 72-00-00) (SIN 83005). Refer to Figure 417 and do as follows:
NOTE:
Two people are necessary to install the fan platforms. One person carefully applies pressure to two fan blades at the 6:00 o'clock position to separate the blades as much as possible, while the other person inserts the fan platform between the blades.
(1)Do a visual inspection of the inside of each fan platform for foreign objects.
(2)Slowly turn the fan blades until the No. 1 fan blade is at the 6:00 o'clock position. Manually push on the root of the fan blades to turn the fan disk.
(3)Refer to the fan platform plot sheet and install fan platform No. 1, between the No. 1 and No. 2 fan blades.
(4)Install the number No. 2 fan platform between the No. 2 and No. 3 fan blades.
(5)Continue to install the fan platforms in numerical order until all 18 fan platforms are installed.

R.Install the aft support spinner ring (20-100 , 72-00-00) as follows. Refer to Figure 417.
CAUTION:
MAKE SURE THAT THE OFFSET HOLE ON THE AFT SUPPORT SPINNER RING ALIGNS WITH THE OFFSET HOLE ON THE FAN ROTOR DISK POST. DAMAGE TO ENGINE HARDWARE CAN OCCUR.
(1)Assemble the aft support spinner ring to the fan hub disk until the 1-1 mark on the aft support spinner ring matches with the 1-1 mark on the fan rotor disk post.
(2)Make sure that the offset hole on the aft support spinner ring aligns with the offset hole on the fan rotor disk post.
(3)Lubricate the threads and mating surfaces of the 18 bolts (83021) with C02-058  graphite.
(4)Install the 18 bolts (83021) and torque them to 79-93 lb in. (8.9-10.5 N.m) in a criss-cross pattern.
(5)Torque bolts (83021) again to 106-124 lb in. (12-14 N.m) in a criss-cross pattern.
(6)Loosen the bolts (83021) one half turn, then torque them again to 106-124 lb in. (12-14 N.m) in a criss-cross pattern.
(7)Do a 360 degrees torque check to make sure that all bolts (83021) are 106-124 lb in. (12-14 N.m).
