Figure CI–R.11. Outer Combustion Casing Alignment Pin.
3. Two alignment pins (see Figure CI-R.11) may be installed into the compressor discharge casing
at or near the bolt holes nearest to adjacent chambers in the number 5 position.
4. Assemble the number 5 outer casing to the compressor casing using the alignment pins.
5. Adjust the location of the outer casing until the alignment marks made during disassembly are
matched. Tighten two bolts to ensure the location remains fixed.
6. Coat all bolt threads with a light coating of Fel Pro C-102 anti-seize compound, install the bolts
and torque the bolts to the correct values. Remove the alignment pins and install the last two bolts
and torque them to the correct values.
7. Repeat steps 1 through 5 for combustion casings 4, 6, 3, 7, 2, 8, 9, 1 and 10, working from bottom
casing to top casing.
Operation 4 — How to Install the Outer Crossfire Tubes, Packing Rings, Sealing Rings and Split
Washers
1. Insert packing rings in the cavities of adjacent outer casing bosses. Do not compress.
2. Insert sealing rings into bosses but do not compress packing rings. Two bolts may be installed
in each ring to locate rings.
3. Check outer surface of outer crossfire tube to be sure there are no nicks or burrs present. Insert
outer tube through the packing rings until it is roughly centered between the two casing bosses.
4. Remove the bolts installed at step 2 above and install the split rings on each sealing ring. Apply
a thin coat of Fel Pro C–102 to the bolt threads. Install all the bolts through the split washers and
sealing rings into the threaded holes in the bosses.
