Appendix H. 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 assemblies 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:
