General
Fig/item numbers in parentheses in the procedure agree with those used in the EIPC. Only the primary Fig/item numbers are used. For the service bulletin alpha variants refer to the EIPC.
For all the parts identified in a different ATA Chapter/Section/Subject, the applicable ATA Chapter/Section/Subject comes before the Fig/item number.
For standard torque data and procedures, refer to SPM TASK 70-41-00-400-501 and SPM TASK 70-41-02-400-501.
To identify, lubricate and install seal rings, refer to SPM TASK 70-64-02-640-501.
Special torque data are included in the procedure.
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.
To install lockwire, refer to SPM TASK 70-42-05-400-501.
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.
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 the 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.
