For all parts identified in a different Chapter/Section/Subject, the applicable Chapter/Section/Subject comes before the Fig/item number.

Transportation covers/blanks must be removed immediately before installation of the components.

For the torque tightening procedures, refer to the SPM TASK 70-41-00-400-501 and SPM TASK 70-41-01-400-501.

Special torque data and assembly tolerances are included in this procedure.

Special torque data is identified with the symbol * after the torque value.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

Make sure that the circuit breaker(s) is (are) open, safetied and tagged.

Procedure

    1. SUBTASK 71-00-02-110-001 Clean the Seals

      WARNING

      CLEANING FLUID IS CLASSIFIED AS A HAZARDOUS MATERIAL WHICH CAN CAUSE INJURY OR ILLNESS IF NOT PROPERLY USED. THIS PRODUCT MUST BE USED ONLY IN ACCORDANCE WITH THE MANUFACTURER'S SPECIFIC HEALTH AND SAFETY RECOMMENDATIONS. PRIOR TO USE OF THIS PRODUCT, CAREFULLY READ THE APPLICABLE "MATERIAL SAFETY DATA SHEET" AND OBEY ALL LISTED SAFETY AND HEALTH PRECAUTIONS.

    1. Clean the surface of the E-seals with a clean cloth made moist with CoMat 01-076 METHYL ETHYL KETONE.

    2. SUBTASK 71-00-02-220-001 Visually Inspect the Seals

    1. Inspect the seals for signs of oxidization, carbon flakes and foreign substances left on the seal from contact with the mating flanges.

    2. Inspect the surface and the edges of the seal for dents, pitting, cracks, scratches and distortion.

    3. If any substance cannot be removed from the seals or if damage exists, the seal should be replaced.

    3. SUBTASK 71-00-02-420-151 Install the Thermal Anti-Ice (TAI) Valve

    1. Refer to Fig. 72-00-02-990-501.

      2. Install the Valve ENGINE-AIR INTAKE ANTI ICE VALVE (30-21-51,01-010).

      1. Remove the blanking caps from the electrical connectors.

      2. Remove the blanking plugs from the disconnected line ends.

      3. Put the anti-ice valve ENGINE-AIR INTAKE ANTI ICE VALVE (30-21-51,01-010) between the forward duct and the nozzle duct. Make sure that the flow arrow on the valve points to the nozzle duct and the index mark is aligned with the forward duct.

        4. Attach the anti-ice valve ENGINE-AIR INTAKE ANTI ICE VALVE (30-21-51,01-010) to the ducts:

        1. CAUTION

          MAKE SURE THE SMOOTH CIRCULAR SURFACE OF THE COUPLING IS RADIALLY OUTBOARD FROM THE ENGINE. DO NOT LET THE COUPLING TOUCH THE ENGINE COMPONENTS OR STRUCTURE. DAMAGE TO THE COMPONENTS OR STRUCTURE COULD OCCUR.

          Install the E-seal on the anti-ice valve. Attach the anti-ice valve to the ducts with the couplings.

      5. Torque the couplings to between 70 and 85 lbfin (0.79 and 0.96 m.daN). Lightly hit the coupling perimeters with a fiber hammer. Torque the coupling again to the same torque value and lightly hit the coupling perimeter again. Do this procedure again, then torque to the same value.
