A. | Match-drill the thrust channels (84116, 84118) to the aft fan case, if they are new as follows: |
(1) | Match-drill the thrust channels (84116, 84118) to the aft fan case, if they are new as follows. Refer to Figure 1002. |
CAUTION: |
|
(a) | Put the thrust channel (84116, 84118) on the outer diameter of the aft fan case (84100) as follows: |
1 | Align the thrust channel (84116, 84118) to the aft fan case. Use the undersized pilot hole in the aft fan case and the undersized hole in the thrust channel to align. |
2 | Install a 0.240 inch (6.10 mm) stepped pin into the pilot hole in the thrust channel (84116, 84118) and the pilot hole in the aft fan case from one end to the opposite end. |
NOTE: |
|
NOTE: |
|
NOTE: |
|
3 | Keep a gap of 0.0000-0.0100 inch (0.000-0.254 mm) between the bottom surface of the lip on the end to the opposite end on the thrust reverser channel (84116, 84118). |
4 | Use a non-abrasive scissor clamp to secure the thrust channel (84116, 84118) to the aft fan case. |
5 | Attach a scissor clamp every 15 inches (381.0 mm). |

CAUTION: |
|
CAUTION: |
|
(b) | Match-drill through the thrust channel (01-060) (SIN 84116) and (01-070) (SIN 84118), and the aft fan case (01-035) (SIN 84100). Drill at the hole adjacent to the pilot holes in the thrust channel (01-060) (SIN 84116) and (01-070) (SIN 84118), and the aft fan case (01-035) (SIN 84100). Use a 0.243 inch (6.17 mm) diameter drill bit. Make sure that the drill stays level so the screws (01-090) (SIN 84424) are against the thrust channel and the aft fan case (01-035) (SIN 84100) in the correct position. |
(c) | Install an avdel pin, a slave bolt, washer, and self-locking nut, or equivalent through the match-drilled hole and tighten into position. This will hold the thrust channel (84116, 84118) in the correct position in relation to the aft fan case (84100). |

Subtask 72-21-00-440-736 |
(4) | Apply C01-176 RTV to the gap between the OGVs as follows: |
(a) | Immediately use a spatula or a wooden depressor to smooth the C01-176 RTV. Remove all excess C01-176 RTV and make a smooth surface that is flush to the surface. The C01-176 RTV must not extend onto the OGVs more than the filled gap. |
(b) | Make sure the C01-176 RTV is smooth, and without lines, bubbles, and voids. |
(c) | The C01-176 RTV should be thick enough to fill the gap and provide good coverage. |
NOTE: |
|
(d) | After you apply the C01-176 RTV to five gaps between the OGVs, remove the C10-021 tape from the inside diameter gap where the RTV was applied first. Carefully smooth any RTV that changed when removing the tape. |
(e) | Continue to apply the C01-176 RTV between the OGV gaps until you have filled the gap between the 48 OGVs. |
(5) | Let the C01-176 RTV to dry a minimum 2 hours. |
(6) | Remove the C10-021 tape from the backside of the OGVs gap. |
(7) | Keep removing the tape only if the C01-176 RTVRTV is not damaged when removing the tape. |

(8) | Wipe off unwanted C01-159 RTV primer from the inboard and the outboard edges of the OGVs with a clean C10-182 cloth as follows: |
WARNING: |
|
(a) | Remove unwanted C01-159 RTV primer that remains around the inboard and the outboard surfaces of the primer with C04-035 isopropyl alcohol or C04-003 acetone. |

Y. | Clean the inside and outside diameter of the stator case assembly as follows: |
WARNING: |
|
(1) | Remove all loose debris with clean, dry compressed air. |
WARNING: |
|
(2) | Use a C10-182 cloth moist with C04-035 isopropyl alcohol to clean the stator case assembly. |
Subtask 72-21-00-210-005 |
Z. | Inspect the stator case assembly. Refer to TASK 72-00-01-200-801 (72-00-01, INSPECTION 001) and do as follows: |
(1) | Look for tape that has not been removed, and remove all tape from the stator case assembly. |
(2) | Look at the aft acoustic panels (01-510) (SIN 83504), (01-520) (SIN 83505), (01-530) (SIN 83506), (01-660) (SIN 8350A), (01-670) (SIN 8350B), (SIN 8350C) and (SIN 8350D), and the acoustic liner (01-500) (SIN 83503) or (01-501) (SIN 83503) on the aft fan case (01-035) (SIN 84100) for chips, scratches, or poorly matched paint. |
(3) | Look at the RTV beads for voids and a smooth change from one surface to the next surface. |
(4) | Do an inspection of the abradable shroud on the fan containment case (01-010) (SIN 83500) or (01-011) (SIN 83500) or (01-012) (SIN 83500) for voids and damage. |
(5) | Look for scratched or nicked areas on the inner surfaces of the stator case assembly. |
(6) | Look at the trench filler areas on the abradable panels of the fan containment case for exposed fibers. |
(7) | Do random torque checks as follows: |
(a) | Check the torque on the aft fan case yoke (yoke) (84803) self-locking nuts (84141) as follows: |
1 | Apply torque 69 to 81 lb ft. (94 to 110 Nm) to all the engine mount self-locking nuts on OGVs 1, 2, and 48. |
2 | Check the torque again on all self-locking nuts (84841) on OGVs 1, 2, and 48, if there are self-locking nuts not sufficiently torqued. |
(b) | Check the torque on the aft fan case yoke self-locking nuts (84840) as follows: |
1 | Apply torque 125 to 145 lb ft. (169 to 197 Nm) to all the engine mount self-locking nuts on OGVs 1, 2, and 48. |
2 | Check the torque again on all self-locking nuts (84841) on OGVs 1, 2, and 48, if there are self-locking nuts not sufficiently torqued. |
(c) | Check the torque on the OGVs 3-47 (8400A, 8400C, 8400D, 8400E, 8400F, 8400G, 8400H, 8400K) self-locking nuts (84143, 84144) as follows: |
1 | Apply torque 368 to 432 lb in. (41.6 to 48.8 Nm) to all self-locking nuts (84143, 84144) on the OGVs 3-47. |
2 | Check the torque again on all self-locking nuts (84843, 84144) on OGVs 3-47, if there are self-locking nuts not sufficiently torqued. |
(d) | Check the torque on the aft fan case to the fan containment case assembly (01-010) (SIN 83500) or (01-011) (SIN 83500) or (01-012) (SIN 83500) split line self-locking nuts (01-040) (SIN 83540) as follows: |
1 | Apply torque 201.6 to 258.4 lb in. (22.78 to 29.22 Nm) to all the split line self-locking nuts. |
2 | Check the torque again on all split line self-locking nuts (83540), if there are self-locking nuts not sufficiently torqued. |
