General

This TASK gives the procedure to install the No. 2 and No. 3 bearing oil feed tubes, the NF electrical harness and the P2.5CM tube.

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 70-41-02-410-501 .

To identify, lubricate and install seal rings, refer to the SPM TASK 70-44-01-400-501.

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.

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 procedure.

The No.1 strut, which is the top position strut of the fan frame, is identified by the five pressure tubes on the No. 1 strut leading edge.

NOTE

To identify the consumable materials refer to the PCI.
