Common Information

TASK 72-41-20-440-005-A00 HPC Rear Cases And Vanes Assembly - Assemble The HPC Stage 11 Stator Vanes To The Cases, Assembly-005

General

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 TASK 70-41-00-400-501, TASK 70-41-01-400-501 and TASK 70-41-02-410-501

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.

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 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.

The Fits and Clearances, NEW PART DIMENSIONS and REJECT IF MORE THAN columns will be used by most operators. This permits the full use of the maximum wear allowance and a reduction in the number of parts which are rejected, is possible.

The column WORN PART DIMENSIONS (Non-select) is included for operators who want to have full interchangeability. If this column is used an increase in the number of parts which are rejected is possible.

After the part has been in service for some time the REJECT IF MORE THAN and WORN PART DIMENSIONS could be changed. The operator must tell IAE and if agreed the manual will be changed.

The abbreviation Intf shows an interference or tight fit. This causes REJECT IF MORE THAN to become REJECT IF LESS THAN.

The abbreviation clear shows a clearance fit.

This TASK gives the procedures to assemble the HP compressor stage 11 case, the vanes, the liners and the stator vane stops. The subsequent TASKS give the procedures to assemble the remaining HP compressor rear cases and vanes.

TASK 72-41-20-440-001-A00 (ASSEMBLY-001, CONFIG-001) Assemble the HP Compressor Stage 7 Cases and Stator Vanes.
