3 . Procedure.
Subtask 72-21-00-440-617
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:
BE CAREFUL WHEN YOU CLAMP. YOU COULD SCORE OR SCRATCH THE AFT FAN CASE OR THE THRUST REVERSER CHANEL.
(a)Put the thrust channel (84116, 84118) on the outer diameter of the aft fan case (84100) as follows:
1Align 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.
2Install 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:
Large diameter of stepped pin has to be left to right.
NOTE:
The diameter of the stepped pin must be no more than 0.002 inch (0.05 mm) smaller than the pilot holes in the thrust channel (84116, 84118) and the aft fan case.
NOTE:
The two axial tabs on the thrust channel (84116, 84118) must be tight against the aft edge of the aft fan case (84100) for correct axial position.
3Keep 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).
4Use a non-abrasive scissor clamp to secure the thrust channel (84116, 84118) to the aft fan case.
5Attach a scissor clamp every 15 inches (381.0 mm).
6The holes in each thrust channel (84116, 84118) must align with the pilot hole in the aft fan case.
CAUTION:
THE PILOT HOLE IN THE UPPER SEAL RETAINER FITTING IS LARGER THAN THE PILOT HOLE IN THE AFT FAN CASE. BE SURE THAT THESE TWO HOLES ARE CONCENTRIC BEFORE YOU MATCH-DRILL. IF THEY ARE NOT CONCENTRIC, THE UPPER SEAL RETAINER CAN HAVE A POSITION THAT IS NOT CORRECT.
CAUTION:
THE DRILL MUST STAY LEVEL TO PREVENT THE DRILLED HOLE FROM ANGLING UP OR DOWN.
(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).
(d)Do this procedure again for the remaining holes in the thrust channel (84116).
(e)Install a new 0.2500 inch (6.350 mm) diameter spiral fluted reamer in a drill gun.
WARNING:
MAKE SURE THAT THE REAMER IS COMPLETELY VERTICAL TO PREVENT DAMAGE OR INJURY.
(f)Make sure that the drill gun is in the correct position and locked.
(g)Start the drill gun and set the controls to the slowest speed and feed settings.
WARNING:
REFER TO THE PRODUCT LABEL AND THE MANUFACTURER'S (MATERIAL) SAFETY DATA SHEET FOR INSTRUCTIONS ON THE HAZARDS, STORAGE, SAFE HANDLING AND PROPER USE OF THIS PRODUCT.
(h)Ream through the thrust channel (84116, 84118) and the aft fan case (84100). Use C02-047  lubricant when you ream.
NOTE:
If the reamer becomes clogged, a new 0.2400 inch (6.096 mm) diameter intermediate reamer with a bush or equivalent can be used at each bolthole.
(i)After the reamer goes through the thrust channel (84116, 84118) and the aft fan case (84100), slowly remove it, but do not turn off the drill gun.
(j)Turn off the drill gun after you remove the reamer from the hole.
(k)Chamfer and deburr the aft fan case (84100) and the thrust channels (84116, 84118) drilled holes.
(l)Remove all raised material and sharp edges. Refer to TASK 70-42-00-350-002 (BLENDING AND REMOVAL OF HIGH METAL PROCEDURES).
(m)Do the procedure again for the remaining holes in the thrust channel (84116, 84118) and the aft fan case.

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.
2Check 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:
1Apply torque 368 to 432 lb in. (41.6 to 48.8 Nm) to all self-locking nuts (84143, 84144) on the OGVs 3-47.
2Check 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:
1Apply torque 201.6 to 258.4 lb in. (22.78 to 29.22 Nm) to all the split line self-locking nuts.
2Check the torque again on all split line self-locking nuts (83540), if there are self-locking nuts not sufficiently torqued.
