Common Information

TASK 71-00-02-400-007-A00 (A1-PPBU) - Install The Drains Mast And The LP Compressor/Intermediate Case Module Drains, Installation-007

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 70-41-00-400-501 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 OILSunless other lubricants are referred to in the procedure.

Transportation covers/blanks must be removed immediately before installation of the components.

For lockwire data and procedures refer to the SPM TASK 70-42-05-400-501.

After assembly apply CoMat 07-032 ENAMEL, POLYURETHANE, AIR-DRYING, TWO-PART, GREY to any damaged surface protection, joint flanges and attach parts. Use the correct color of the air drying enamel. Refer to the SPM TASK 70-38-07-380-501.

Loosely assemble the tubes together and the clip positions during the installation procedure. This will give flexibility and movement and not put strain on the tubes. Where access allows, fully torque the tube nuts and then the clip positions when all the tubes are connected and installed. Torque the nuts securing the tubes at the bifurcation panel after all the tubes have been installed. Refer to each specific step for the torque values and procedure at the point of application.

Torque the tube nuts and clips so that the tubes are free of preload and have a minimum clearance of 0.25 in. (6.4 mm) with adjacent components and structure. A minimum clearance of 0.02 in. (0.5 mm) is permitted between clip positions 0950 and 0951, between the gearbox and the air starter drain tube (221) and IDG drain tube (229). A minimum clearance of 0.06 in. (1.5 mm) is permitted between the gearbox and the FMU drain tube (225) on the collector plate assembly. Refer to the SPM TASK 70-42-01-400-501 to tighten tube end connectors. Make sure that the tubes always have support to prevent unwanted strain.

NOTE

To identify the consumable materials refer to the PCI.
