Common Information

TASK 72-32-70-440-001-B00 LPC Bleed Valve And Actuating System - Assemble, Assembly-001

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.

For standard torque data and procedures refer to the SPM TASK 70-64-02-640-501 and SPM TASK 70-41-02-400-501.

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

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

To identify and install key washer, refer to the SPM TASK 70-42-03-400-501.

Refer to Figure. or the view of the booster stage valve and actuating mechanism.

The abbreviation Intf 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.

NOTE

To identify the consumable materials refer to the PCI.

NOTE

Special tools are identified in the procedure by the tool primary number.
