REPLACEMENT PARTS LIST
7.1 UNIT NUMBERING METHOD
The method of numbering used throughout the unit is assigning reference
designations (electrical symbol numbers) to identify: assemblies,
subassemblies, modules within a subassembly, and discrete components.
An example of the unit numbering method used is as follows:
Subassembly Designation A1
R1 Class and No. of Item
Identify from right to left as:
First (1) resistor (R) of
first (1) subassembly (A)
On the main chassis schematic, components which are an integral part of
the main chassis have no subassembly designations.
7.2 REFERENCE DESIGNATION PREFIX
The use of partial reference designations are used on the equipment and on
the manual illustrations. This partial reference designation consists of the
component type letter(s) and the identifying component number. The
complete reference designation may be obtained by placing the proper
prefix before the partial reference designation. Reference designation
prefixes are included on the drawings and illustrations in the figure titles
(in parenthesis).
7.2.1 PROVISIONING NOTE - INCONSISTENCIES
IN PART NUMBERING CONVENTIONS
The internal computer applications at the factory
have undergone upgrades
to better serve our customers. With this upgrade came alterations to the
numbering scheme for parts reporting to an end item. Due to these
alterations, minor inconsistencies may exist between identifying parts
numbers found on drawings, piece parts, or other documentation. No form
fit and function specifications have been altered due to this change in the
numbering scheme.
The inconsistencies take two forms. New part number conventions
mandate the use of three-digit suffixes for part numbers used within
computer applications. Part numbers having single-digit suffixes have
been altered by the addition of leading zeroes. Therefore, a piece part with
an identifying number having a suffix of “-2” may be represented in a
computer-generated document with a part number having a suffix of
“-002”. Also the new part numbering convention requires that the base
portion of a part number be made up of six digits. Part numbers with base
portions with less than six digits are expressed with leading zeroes to meet
