OVERVIEW
The Parts List section identifies all part numbers and the cor-
responding location of all spared subsystem components.
ORGANIZATION
PARTS LISTS
Each item number in the part number listing corresponds to an
item number in the related illustration. All the parts in a given
subsystem of the machine will be located in the same illustration
or in a series of associated illustrations.
ELECTRICAL CONNECTORS AND FASTENERS
This section contains the illustrations and descriptions of the
plugs, jacks, and fasteners used in the machine. A part number
listing of the connectors is included.
COMMON HARDWARE
The common hardware is listed in alphabetical order by the letter
or letters used to identify each item in the part number listing and
in the illustrations. Dimensions are in millimeters unless otherwise
identified.
PART NUMBER INDEX
This index lists all the spared parts in the machine in numerical
order. Each number is followed by a reference to the parts list on
which the part may be found.

USE OF THE TERM "ASSEMBLY"
The term "assembly" will be used for items in the part number
listing that include other itemized parts in the part number listing.
When the word "assembly" is found in the part number listing,
there will be a corresponding item number on the illustrations
followed by a bracket and a listing of the contents of the as-
sembly.
BRACKETS
A bracket is used when an assembly or kit is spared, but is not
shown in the illustration. The item number of the assembly or kit
precedes the bracket; the item numbers of the piece parts follow
the bracket.
The notation "WTTag" in the parts description indicates that the
part configuration has been updated. Check the change Tag
index in the General Information section of the Service Data for
the name and purpose of the modification.
In some cases, a part or assembly may be spared in two versions:
with the Tag and without the Tag. In those cases, use whichever
part is appropriate for the configuration of the machine on which
the part is to be installed. If the machine does not havea particular
Tag and the only replacement part available is listed as " WTTag,"
install the Tag kit or all of the piece parts. The Change Tag Index
tells you which kit or piece parts you need.
Whenever you install a Tag kit or all the piece parts lhat make up
a Tag, mark the appropriate number on the Tag matrix.
