newton-meters). 2) Without loosening, tighten the bolts again until the torque is kept.
(f)
Lubricate the threads of the bolts that attach the right TVCA duct to the TVCA valve.
(g)
Install the right TVCA duct to the TVCA valve with the bolts. 1) Tighten the bolts to 85-95 pound-inches (9.6-10.7 newton-meters).
2) Without loosening, tighten the bolts again until the torque is kept.
(h)
Lubricate the threads of the bolt that attaches the link rod end to the bracket.
(i)
Install the link rod end to the bracket with the bolt and the nut. 1) Tighten the bolt to 36-40 pound-inches (4.1-4.5
newton-meters).
(j)
Lubricate the threads of the adapter for the air signal tube with antigalling compound.
(k)
Connect the air signal tube to the adapter. 1) Hold the adapter and tighten the tube nut to 200-225 pound-inches (22.6-25.4 newton-meters).
2) Safety the tube nut with lockwire or safety cable and safety cable ferrule.

TURBINE VANE COOLING AIR VALVE AND TURBINE VANE AND BLADE COOLING AIR
_____________________________________________________________________
VALVE SOLENOID - REMOVAL/INSTALLATION
_____________________________________
1. General_______
A. This procedure is for engines with the Phase 3 changes. For engines
without the Phase 3 changes, do this procedure: HPC Secondary Flow
Control Valve and Turbine Vane and Blade Cooling Air Valve Solenoid
Removal/Installation (AMM 75-33-03/401).
B. This procedure gives the instructions for the removal and the
installation of the solenoid for the Turbine Vane Cooling Air (TVCA)
valve and the Turbine Vane and Blade Cooling Air (TVBCA) valve. The
solenoid for the TVCA valve and the TVBCA valve will be referred to as
the solenoid for this procedure.
C. The solenoid is installed on the aft face of the intermediate case at the 10 o'clock position.
D. You can get access to the solenoid through the left thrust reverser.
