General
This TASK gives the procedure to install the components and the air off take ducts on the HP compressor/diffuser case assembly. Refer to the TASKS which follow for other related procedures:
TASK 72-00-40-420-005-A00 (INSTALLATION-008, CONFIG-001) or TASK 72-00-40-420-005-B00 (INSTALLATION-008, CONFIG-002). Install the components, the ducts, the electrical harnesses and the tubes on to the HP compressor case vertical split line.
TASK 72-00-40-420-006-A00 (INSTALLATION-009, CONFIG-001) or TASK 72-00-40-420-006-B00 (INSTALLATION-009, CONFIG-002). Install and connect the components, the electrical harnesses and the tubes on to the front of the HP compressor case.
TASK 72-00-40-420-007-A00 (INSTALLATION-010, CONFIG-001) or TASK 72-00-40-420-007-B00. Install the components, the electrical harnesses and the tubes on to the HP turbine.
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.
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.
For standard torque data and procedures refer to SPM TASK 70-41-01-400-501.
Special torque data is identified with the symbol * after the torque value.
Assembly tolerances are included in this procedure.
For lockwire data and procedures refer to SPM TASK 70-42-05-400-501.
Safety the threaded fasteners in this TASK with CoMat 02-274 SAFETY CABLE KIT or CoMat 02-275 SAFETY CABLE KIT for the ATA Chapter/Section/Subjects which follow:
For safety cable data and procedures refer to SPM TASK 70-42-08-400-501.
Refer to the V2500 Illustrated Tool and Equipment Manual (ITE-V2500-1IA) for the illustrations of the special tools used in this procedure.
Transportation covers/blanks must not be removed until immediately before installation of the components.
Do not remove the special plastic caps from electrical connections or tube connections which are not applicable in this procedure. This will give protection from unwanted material.
Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-077 APPROVED ENGINE OILS unless other lubricants are referred to in this procedure.
After assembly apply CoMat 07-038 AIR DRYING ENAMEL damaged surface protection, joint flanges and attach parts. Use the correct color of air drying enamel. Refer to SPM TASK 70-38-21-380-501.

Refer to Figure.
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 of fluids do not go in to the electrical connector.
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.
