TASK 75-24-49-440-101-B00 LPT ACC Air Ducts And Tubes - Assemble The Support Assemblies To The Tubes And Ducts, Assembly-001 - SBE 75-0001

General

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

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

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

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

WARNING

DO NOT GET ANTI-SEIZE PASTE ON YOUR SKIN WHEN YOU LUBRICATE THREADS AND ABUTMENT FACES OF NUTS AND BOLTS. WEAR PROTECTIVE GLOVES.

Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-129A ANTI-SEIZE PASTE, unless other lubricants are referred to in the procedure.

To identify, lubricate and install seal rings, refer to SPM TASK 70-44-01-400-501.

After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and attach parts. Use the correct color of the air drying enamel. Refer to SPM TASK 70-63-02-380-501.

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.

Refer to Figure for a view of the LP turbine ACC assembly.

NOTE

The support assemblies of PRE SBE 75-0001 and SBE 75-0001 configurations are interchangeable. For SBE 75-0001 configuration, refer to Assembly-001 TASK 75-24-49-440-101-A00.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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