Common Information

TASK 72-32-70-440-001-A00 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, SPM TASK 70-41-00-400-501 and SPM 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.

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

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

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.

Refer to Figure for a view of the booster stage bleed valve and actuating mechanism, Pre SBE 72-0133.

Refer to Figure for a view of the booster stage bleed valve and actuating mechanism, SBE 72-0133.

This TASK gives the procedure to assemble the booster stage bleed valve and actuating mechanism.

NOTE

To identify the consumable material refer to the PCI.

NOTE

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