TASK 72-00-32-450-007 LPC/Intermediate Case Module Components - Install The Air Modulating Valve, Installation-014

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.

Lubricate all threads and abutment faces of nuts and bolts with CoMat 10-039 ENGINE OIL, unless other lubricants are referred to in the procedure.

Do not remove the special plastic caps from the electrical connectors and receptacles until immediately before they are connected. This will give protection from unwanted fluids or materials.

During the installation procedure make sure that the harnesses are held temporarily along their different lengths. This is to prevent too much strain on the harnesses, cables and electrical connectors.

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

For the torque tightening procedures, refer to the SPM TASK 70-41-00-400-501 and TASK 70-41-01-400-501.

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

Special torque data is identified with the symbol * after the torque value.

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.

Safety the threaded fasteners in the ATA Chapter/Section/Subject 71-51-41 as applicable with CoMat 02-274 SAFETY CABLE KIT or CoMat 02-275 SAFETY CABLE KIT.

NOTE

To identify the consumable materials refer to the PCI.
SBE 70-0813 : Announcement of introduction of safety cable as a preferred method to lockwire.
