Operation 14 — How to Reassemble Exhaust and Inlet Duct Access Panels
1. On a straight up exhaust configuration 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 bolting 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 underneath the overhang of the duct transition piece.
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 panel.
6. Reassemble the exhaust plenum forward flex seals gaskets and clamp bars between the exhaust
hood frame and plenum. See Figure HGP-R.8.
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 inlet ple-
num access panel located in the lower right hand section of the plenum, looking with air flow.
Coat bolts with anti-seize compound, install access panel and bolt in place.
Operation 15 — How to Assemble Turbine Compartment Roof, Side Panels and Doors
1. Reassemble lagging side panel vertical beams if they were removed at disassembly.
2. Attach four eyebolts to threaded receptacles on the roof. Rig the roof (include chainfall in rigging)
for lifting.
3. Apply new gasketing or caulking to roof section.
