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

Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-077 APPROVED ENGINE OILS, unless other lubricants are referred to in the procedures.

Discard all tab washers removed in this procedures.

To identify and install tab washers, refer to SPM TASK 70-42-03-400-501.

For standard torque data and procedures, refer to the SPM TASK 70-41-00-400-501, SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-400-501.

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

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

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

NOTE

To identify the consumable materials refer to the PCI.

Procedure

    1. SUBTASK 72-00-32-210-093 Make Sure of the LPC Bleed Valve Actuating Master, Slave Actuators and the Brackets

    1. Make sure that the actuators and the brackets are removed from the fan frame. If they are installed, remove them. Refer to TASK 72-00-40-020-002-A00 (REMOVAL-002, CONFIG-001).

    2. SUBTASK 72-00-32-210-094 Replace the Tab Washers

    1. Refer to Figure, Figure and Figure.

      2. Remove the rear rod end bearings from the right and left rod assemblies.

      1. Bend back the tabs on each tab washer to release the jam nut ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-180) and ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-480).

      2. Loosen each jam nut.

      3. Remove the rear rod end bearing and the jam nut from each rod assembly.

    3. Remove the rear tab washers ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-170) and ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-470) from right and left rod assemblies. Discard the tab washers.

      4. Install the rear rod end bearings ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-190) and ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-490) to the right and left rods ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-200) and ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-500).

      1. NOTE

        Set the installation length of the rod end bearing approximately 1.00 in. (25.4 mm).
        Do not bend the tabs of the rear washers.
        Tighten the nuts lightly.

        Install the jam nuts ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-180) and ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-480) and the new rear tab washers ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-170) and ENGINE-BLEED VALVE ACTUATING ROD ASSEMBLY (72-32-75, 01-470) to the right and left bearings with the nuts.
