INTRODUCTION

Page 5 May 05/2009
 

(1)  
If a part number is known and it is required to locate the part, find the part number in the Numerical Index, section 71-00-00, and note the section, figure and item number in which it is used.

Locate the figure and identify the item number on the text page facing the illustration.

(2)  
If the part number is not known, but the system or general area on the engine is, it may be possible to locate the applicable figure from the alphabetical listing of installations in the Installation Index, 71-00-00, or from the sequential listing in Figure 1-1, 71-00-02.

D.  Use of Assembly Procedures
(1)
Assembly procedures assume engine is supported on floor pedestals, PWA80004, or overhead sling, B71027.

(2)  
Use of locating jig, B71032, is recommended to ensure correct alignment of ducts and tubing, and adequate wire bundle lengths prior to installation of engine to strut.

(3)  
Each area of work or procedural sequence is illustrated with the instructions and parts list on the facing page. Parts are listed immediately following the procedural step in which they are installed.

(4)  
Vendor codes are listed for vendor parts in the parts list nomenclature. A list of vendors, their codes and addresses is provided in paragraph 6.

(5)
Special torque requirements are specified where applicable. When torque values are not specified, standard torque tables will apply.

(6)  
Consumable materials, such as lubricants, sealants and tapes specified in buildup procedures are listed in the 71-00-00 with specification or vendor source and areas where they are used.

E.  Terms Used In Procedure
(1)  
AR -Parts with AR (AS REQUIRED) in the QTY (quantity) column can be used as required.

(2)  
DEL -Parts with DEL (DELETED) in the UC (usage code) column, and a dash in the QTY (quantity) column should not be used or reinstalled.

(3)  
OPT -Parts with OPT (OPTIONAL) in the nomenclature column, OPT in the UC (usage code) column, and a dash in the QTY (quantity) column, are optional and interchangeable with the same item number listed with a quantity. Part numbers listed with a quantity are preferred, and should be used if available.

(4)  
REF -Parts with REF (REFERENCE) in the UC (usage code) column and a dash in the QTY (quantity) column have been previously called out.

(5)  
REPLD BY -Parts with REPLD BY (REPLACED BY) in the nomenclature column, LTD (LIMITED) in the UC (usage code) column, and a dash in the QTY (quantity) column have been installed on production engines and supplied with early QEC kits. These parts should no longer be used or ordered for a new QEC kit installation. Parts having the same item number with a quantity are improved versions or are necessary due to basic engine changes and are supplied in later QEC kits.
