Common Information

TASK 72-41-30-440-008-B00 HPC Front Case And Vane Assembly - Install The Variable Inlet Guide Vane And The Stage 3 To 5 Connectors, Assembly-008

General

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 70-41-01-400-501 and SPM TASK 70-41-00-400-501.

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

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

To identify, lubricate and install seal rings, refer to SPM TASK 70-64-02-640-501.

For lockwire data and procedures refer to SPM TASK 70-42-05-400-501.

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

The number for each raDiameterl 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 front case.

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.

As long as REJECT IF MORE THAN columns do not include reject values, NEW PART DIMENSIONS do not have to be measured before assembly, as there are no reject-if criteria. Values are only valid for new parts, not for worn parts.

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 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 procedure to install the variable inlet guide vane and stage 3 to 5 connectors. The subsequent TASK gives the procedure to assemble the HP compressor front cases.

Install the HP Compressor Stage 4 and 5 Rotor Path Rings and Stage 6 Rotor Ring Segments by TASK 72-41-30-440-001-C00 (ASSEMBLY-001).

Measure and then Machine the Stage 6 Stator Vanes and the Stage 4, 5 and 6 Rotor Path Rings by TASK 72-41-30-440-002-B00 (ASSEMBLY-002).

Install the Variable Inlet Guide Vanes by TASK 72-41-30-440-003-B00 (ASSEMBLY-003).

Install the Stage 3 Stator Vanes by TASK 72-41-30-440-004-B00 (ASSEMBLY-004).

Install the Stage 4 Stator Vanes by TASK 72-41-30-440-005-B00 (ASSEMBLY-005).

Install the Stage 5 Stator Vanes by TASK 72-41-30-440-006-B00 (ASSEMBLY-006).

Install the Stage 6 Stator Vanes by TASK 72-41-30-440-007-B00 (ASSEMBLY-007).

Measure the HP Compressor Front Cases by TASK 72-41-30-440-009-B00 (ASSEMBLY-009).

Disassemble the HP Compressor Front Cases by TASK 72-41-30-440-010-B00 (ASSEMBLY-010).

Check and Set VSV System with Optimised Build and Setting Clearances - SBE 72-0400 by TASK 72-41-30-440-011-B00 (ASSEMBLY-011).
