Procedure

 S 424-030-N00
 (1)  
Install the PS3 air filter:

 (a)  
Remove the protection caps from the PS3 air filter (3) and all open line ends.

 (b)  
For the right PS3 air filter (3), do the steps that follow: 1) Lubricate the threads of the bolts (4) with engine oil. 2) Attach the PS3 air filter (3) to the flange J bracket with

 the bolts (4). a) Tighten the bolts (4) to 36-40 pound-inches (4.1-4.5 newton-meters).

 (c)  
For the left PS3 air filter (3), do the steps that follow: 1) Lubricate the threads of the bolts (5) with engine oil. 2) Attach the PS3 air filter (3) to the flange J bracket with

 the bolts (5). a) Tighten the bolts (5) to 36-40 pound-inches (4.1-4.5 newton-meters).

 (d)
Lubricate the tube nuts (2) with the antigalling compound.

 (e)  
Connect the tube nuts (2) to the PS3 air filter (3). 1) Tighten the tube nuts (2) to 200-225 pound-inches (22.6-25.4 newton-meters). 2) Safety the forward tube nuts (2) to the hex adapters with

 lockwire or safety cable and safety cable ferrule. 3) For the upper PS3 air filter (3), safety the rear tube nut
 (2) to the head of the PS3 air filter (3) with lockwire or safety cable and safety cable ferrule.

HPC SECONDARY FLOW CONTROL VALVE AND TURBINE VANE AND BLADE COOLING
___________________________________________________________________
 AIR VALVE SOLENOID - REMOVAL/INSTALLATION

_________________________________________
 1.  General_______
 A.  This procedure is for engines without the Phase 3 changes. For engines
 with the Phase 3 changes, do this procedure: Turbine Vane Cooling Air
 Valve and Turbine Vane and Blade Cooling Air Valve Solenoid
 Removal/Installation (AMM 75-24-17/401).

 B.  This procedure gives the instructions for the removal and installation of the solenoid for the High Pressure Compressor (HPC) secondary flow control valve and the turbine vane and blade cooling air valve. The solenoid for the HPC secondary flow control valve and the turbine vane and blade cooling air 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.
