Appendix C. Parts Listing
This parts listing contains reference drawings and a corresponding index for all field replaceable parts.
The index provides the part number, the quantity required (units), and a description of the part.
Listed below is additional information about the parts assembly index.
SIMILAR ASSEMBLIES: If two assemblies contain a
majority of identical parts, they are broken down on the
same list. Common parts are shown by one index
number. Parts specific to one or the other of the assem-
blies are listed separately and identified by description.
AR: (As Required) in the Units column indicates that the
quantity is not the same for all machines.
NP: (Non-Procurable) in the Units column indicates that
the part is non-procurable and that the individual parts or
the next higher assembly should be ordered.
NR: (Not Recommended) in the Units column indicates
that the part is procurable but not recommended for field
replacement, and that the next higher assembly should
be ordered.
R: (Restricted) in the Units column indicates that the part
has a restricted availability.
INDENTURE: The indenture is marked by a series of
dots located before the parts description. The indenture
indicates the relationship of a part to the next higher
assembly. For example:
Indenture Relationship of Parts
(No dot) MAIN ASSEMBLY
(One dot) Detail parts of a main assembly
(One dot) Subassembly of the main assembly
(Two dots) Detail part of a one-dot subassembly
(Two dots) Subassembly of a one-dot subas-
sembly
(Three dots) Detail part of a two-dot subas-
sembly
