Major Inspection — Reassembly Procedures
Operation 15 — How to Install Inlet Transition Piece Duct and Elbow
1. Check the integrity of the inlet transition duct, inlet elbow and the inlet trash screen.
2. Install new gasket on the inlet transition piece. Rig and lift the transition duct into position on the
inlet plenum.
3. Coat bolting with Fel Pro C-102 anti-seize compound, install bolts and tighten.
4. Install new gaskets on the inlet duct elbow. Rig and lift the inlet elbow into position between the
transition duct and silencing duct.
5. Coat bolts with anti-seize compound, install bolts and tighten.
Operation 16 — How to Reassemble Exhaust and Inlet Plenum Access Panels
1. Spread the exhaust plenum frame using a length of 4 in. pipe or timber and a 10 ton mechanical
jack sufficiently to allow clearance to install the access panel.
2. Assemble new gasket, lift and position the panel into the plenum opening. Coat bolts with Fel
Pro C-102 anti-seize compound, install bolts but do not tighten.
3. Assemble new gasket to the exhaust duct transition piece forward panel. Lift and guide the panel
into position.
Note: Comealongs will be required to help guide and position the panel into
location beneath the overhang of the transition duct.
4. Coat bolts with Fel Pro C-102 anti-seize compound. Install bolts and tighten. Remove the rigging.
5. Tighten the bolts on the exhaust plenum forward panel.
6. Reassemble the forward and aft flex seal plates, gaskets and clamp bars between the exhaust hood
frame and plenum. See Figure MI-R.3.
7. Reinstall the 11th stage extraction piping and compressor bleed valve to the exhaust plenum pan-
el. Reconnect all tubing runs and piping runs to the 11th stage piping and bleed valve.
8. Inspect the inlet plenum for cleanliness and/or foreign objects. Install new gasket on the access
panel located in lower right hand corner of the plenum, looking with air flow. Coat bolts with
anti-seize compound and bolt panel in place.
Operation 17 — How to Recheck Turbine to Load Gear and Turbine to Accessory Gear
Alignment
1. The turbine to load gear and turbine to accessory gear alignment should be rechecked using the
same procedures detailed in disassembly operation 1 in this section.
2. If alignment is within limits (refer to the Basic Alignment Instructions (Field) in the Reference
Drawing section of this Service Manual), no realignment is required, remove the alignment
equipment and fixture.
