Common Information

TASK 72-41-20-440-006-C01 HPC Rear Cases And Vanes Assembly - Machine The Stator Vane Tips And The Rotor Path Ring Liners (Encapsulating Method) - SBE 72-0561 (SelectOne Production Standard), Assembly-006

General

This task gives the procedure for machine the stator vane tips and the rotor path ring liners only for engines, which have SBE 72-0561 (SelectOne Production Standard) incorporated.

Fig/item numbers in parentheses in the procedure 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.

For standard torque data and procedures refer to 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 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 approved engine oil unless other lubricants are referred to in the procedure.

After assembly apply CoMat 07-038 AIR DRYING ENAMEL to any damaged surface protection, joint flanges and parts used to attach. 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 sectional view of the HP compressor rear cases and vanes.

Make sure all the flange faces and tool faces that touch are very clean.

This TASK gives the procedures to machine the stator vane tips and the rotor path ring liners.

For other parts of the HP compressor rear cases and vanes assembly refer to TASK 72-41-20-440-000 (ASSEMBLY-000).
