TASK 72-32-00-430-005 LPC/Intermediate Case Module - Install The No. 1 Bearing Support Assembly, Assembly-005

General

This TASK gives the procedure to install the No. 1 Bearing Support Assembly. For the other parts of the LP Compressor/Intermediate Case Module, refer to TASK 72-32-00-430-000 (ASSEMBLY-000).

Fig/item numbers in parentheses in the procedure agree with those used in the IPC. Only the primary Fig/item numbers are used. For 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.

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

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

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

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 procedure. 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.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

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