Common Information

TASK 72-00-40-420-007-A00 HP System Module - Install The Components, Electrical Harnesses, Tubes, And Brackets To The HPT, Installation-010

General

This TASK gives the procedure to install the components, electrical harnesses, tubes and brackets to the HP turbine module. Refer to the TASKS which follow for other related procedures.

TASK 72-00-40-420-004 (INSTALLATION-007) - Install the initial components, the air off-take ducts and tubes to the HP system module.

TASK 72-00-40-420-005 (INSTALLATION-008) - Install the components, the ducts, the electrical harnesses and the tubes to the HP compressor case vertical splitline.

TASK 72-00-40-420-006 (INSTALLATION-009 CONFIG-001) - Install and connect the components, the electrical harnesses and the tubes to the front of the HP compressor case.

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 the 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 the SPM TASK 70-41-00-400-501, SPM TASK 70-41-01-400-501, SPM TASK 70-41-02-400-501 and SPM TASK 70-41-02-410-510.

Special torque data is identified with the symbol * after the torque value. Assembly tolerances are included in this procedure.

If the cotter pin holes do not align within the torque range a different nut must be used. Do not loosen the nut or tighten the nut more than the maximum torque to align the holes.

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.

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

After assembly, apply CoMat 07-038 AIR DRYING ENAMEL to damaged surface protection, joint flanges and attach parts. Use the correct color of air drying enamel. Refer to the SPM TASK 70-38-21-380-501.

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.

Transportation covers/blanks must be removed immediately before installation of the components.

Do not remove the special plastic caps from the electrical connections until immediately before installation. This will give protection from unwanted fluids and materials. For the data on the connection of the electrical connectors refer to the SPM TASK 70-43-00-400-501.

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

For safety cable data and procedures refer to the SPM TASK 70-42-08-400-501.

    4. SUBTASK 72-00-40-420-135 Electrical Harness Installation Procedure

    1. Refer to Figure

    2. During the installation procedure make sure the harnesses are held temporarily along their different lengths. Always install the datum clip positions when you install each electrical connector. This will give correct installation of the different harnesses, prevent too much strain on the electrical connectors and give the necessary drip loops (the drip loop makes sure moisture or fluids do not go in to the electrical connector).

    3. Because of the differences between the harness diameters, the specified clip could be too large or too small. You can use a clip from a range of six clips that have the same part numbers. If the harness diameter is between two of the clips in the range, use the larger clip. When you do this use CoMat 02-148 ADHESIVE TAPE (ELECTRICAL) to increase the harness diameter.

    4. For the data on the electrical connectors refer to SPM TASK 70-43-00-400-501 and SPM TASK 70-43-01-400-501.
