sleeve and the combustion liner to one of the primary fuel nozzle cups.
7. The detector and cover can then be mounted on the support.
Operation 7 — How to Install the Primary Fuel Nozzle/End Cover Assemblies
1. Insert a new Flexitallic gasket inside the rabbet on each combustion outer casing.
2. Check to insure that the five floating collars on the cap and liner assembly are free to move.
3. Lightly coat the end cover bolt threads with Fel Pro C102 anti-seize compound.
4. Install three eyebolts in the No. 5 end cover and rig so that the cover will hang in the proper
orientation and level during installation into the combustion can.
5. Lift cover and rig a side cable to pull sideways under the compressor.
6. Lower cover and draw over to align with combustion casing.
7. Adjust position until end cover alignment pins slide into their holes.
8. Slide cover axially keeping it square with combustion casing until the rabbet on the end cover
is engaged. Nozzle tip engagement with floating collars is 0.375 inch before the nozzle cover
meets the combustion case.
9. Draw cover up to gasket with three equally spaced bolts if necessary.
10. Install the rest of the cover bolts. Tighten in a criss–cross sequence and remove slings and eye-
bolts.
11. Proceed to install the rest of the covers ending with the top cover.
Operation 8 — How to Install the Secondary Fuel Nozzles
1. Insert a new gasket in the groove of secondary nozzle.
CAUTION
The fuel nozzles are precision machined parts. Do not al-
low them to hit any part of the turbine.
