Common Information

TASK 72-32-00-030-004-C00 LPC/Intermediate Case Module - Remove The Panel Rubber Seals, Middle Liner Panel, And Rear Liner Panels, Disassembly-004

General

This TASK gives the procedure to remove the middle liner panel, the rear liner panels and panel rubber seals.

Fig/item numbers in parentheses in the procedure agree with those used in the IPC. Only the primary numbers are used. For the service bulletin alpha variants refer to the IPC.

Apply the approved penetrating oil before the removal of threaded parts. Let the parts soak before removal. For the approved oils and procedures, refer to the SPM TASK 70-64-00-640-501.

The number for each radial location must be identified in a clockwise direction. These start at the engine top position when you look from the rear of the engine, unless stated differently in the procedure.

The No. 1 strut, which is the top position strut of the fan frame assembly, is identified by the five pressure tubes on the No.1 strut leading edge.

Procedure

    1. SUBTASK 72-32-00-030-157 Remove the Middle Liner Panel and the Rear Liner Panels from the Fan Case

    1. Refer to Figure and Figure.

    2. Make sure that the fan frame and the fan case assembly is installed horizontally on the turnover stand refer to TASK 72-32-00-030-003-B00 (DISASSEMBLY-003, CONFIG-002).

    3. Make sure that the work mat is in position in the fan case. Refer to TASK 72-32-00-030-003-B00 (DISASSEMBLY-003, CONFIG-002).

      4. Remove the middle liner panel and the 10 rear liner panels from the fan case.

      1. Remove the 38 screws (02-820) which attach the middle liner panel and the nine rear panels to the fan case.

      2. Remove the middle liner panel and the nine rear panels from the fan case.

      3. Remove the four screws (02-825) which attach the rear liner panel to the fan case.

      4. Remove the rear liner panel from the fan case.

    2. SUBTASK 72-32-00-030-225-A00 Remove the Panel Rubber Seals (Pre SBE 72-0156)
