TASK 72-00-00-200-016 Engine General - Examine (Borescope) The HPT Stage 1 Duct Segments, Inspection-016

General

This TASK gives the procedure for the borescope inspection of the stage 1 HPT duct segments. This TASK recommends the use of a flexible borescope to inspect the stage 1 HPT duct segments. A rigid borescope will not permit you to see sufficient detail to inspect the duct segments to the limits in this TASK.

NOTE

To identify the consumable materials, refer to the PCI.

NOTE

Special tools are identified in the procedure by the tool primary number.

Procedure

    1. SUBTASK 72-00-00-020-077 Install a Flexible Borescope to Examine the Stage 1 HPT Duct Segments through the T1/2L or T1/2R Ports

    1. Refer to Figure and Figure.

      2. Get access to the stage 1 HPT duct segments through the T1/2L and the T1/2R ports.

      1. Remove the lockwire and the bolts HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-160) which hold the plugs.

      2. Put the IAE 1P16184 Puller puller 1 off into the center hole of the plug.

      3. Remove the plug HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-140) from the port with the puller.

      4. Remove the gasket HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-120) from the plug HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-140).

      5. Remove the plug HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-140) from the puller.

      6. Do Step through Step for the other plug HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-140).

    3. NOTE

      When the borescope is in approximately 12 in. (0.30 m), withdraw the borescope to make sure there is a minimum of resistance. If there is resistance, remove the borescope and rotate the rotor for better position. If there is little or no resistance, continue the borescope installation.

      Put a flexible borescope into the T1/2R port. Twist and push the borescope in until you can see the duct segments.

    4. Continue to install the borescope around the circumference until you can see the borescope at the entrance point. If the borescope cannot go all the way around, slowly retract the borecope to see all the duct segments for heavy wear of the parent metal, burning and missing material.

    5. If the borescope did not go all around the circumference, use port T1/2L and do the borescope installation procedure again to inspect the duct segments that remain.

    2. SUBTASK 72-00-00-420-084 Close the Borescope Inspection Ports after the Borescope Inspection is Completed

    1. Refer to Figure.

    2. Remove the borescope.

      3. For the T1/T2 and the T1/2R port proceed as follows:

      1. Put the gasket HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-120) 1 off in the case recess.

      2. Replace the gasket if the seal is not above the case surface.

      3. Put the gasket on the plug HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-140) and install it in the case.

      5. Install the bolts HP Turbine (HPT) Rotor And Stator Assembly (72-45-00, 01-160).

      6. Torque the bolts to 75 to 85 lbf.in (8.48 to 9.60 Nm).

      7. Safety the bolts with CoMat 02-141 LOCKWIRE.
