Common Information
TASK 71-00-02-400-015-B00 (A5-PPBU) - Install The Fire Detection Harnesses, The Nacelle Temperature And Cabin Services Harnesses And The Core Overheat Detector, Installation-015
General
Transportation covers/blanks must be removed immediately before the installation of components and tubes.
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 the SPM TASK 70-41-01-400-501 and SPM TASK 70-41-02-400-501.
Special torque data is identified with the symbol * after the torque value.
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 attach parts. Use the correct color of air drying enamel. Refer to 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.
Refer to the V2500 Illustrated Tool and Equipment Manual (ITEM-V2500-1IA) for the illustrations of the special tools given in this procedure.
Do not remove the special plastic caps from the electrical connectors until immediately before they are installed. This will give protection from unwanted fluids and materials.
