TAILPIPE EXTENSION -REMOVAL/INSTALLATION
General
A. The tailpipe extension forward mounting flange is attached to the engine, the thrust reverser is attached to the tailpipe extension aft mounting flange. Forty two bolts are used at each flange. The reverser is normally removed and installed at the tailpipe extension aft mounting flange and the tailpipe extension then removed from the engine. However, the extension with reverser attached may be removed as a unit if desired.
2. Equipment and Materials

A. Antiseize Compound -Ease-Off 990, Texacone Corp., Dallas 8, Texas, or equivalent
B. Cart Assembly - F80101 or equivalent
C. Sling Assembly - F80110-1 or equivalent
D. Thrust Reverser Isolation Valve Ground Lock Cap and Pin Assembly - F80109-3 or F80109-9 or equivalent
3. Prepare for Removal
A. Check that thrust reverser deflector doors are stowed and locked.
B. Deactivate thrust reverser hydraulic system by installing ground locks on both thrust reverser isolation valves.

per 78-32-101.
4. Remove Tailpipe Extension
A. Disconnect push-pull cable at quick disconnect (Fig. 401).
