INTRODUCTION
1. Scope
Code
Definition
This manual lists spares and repair parts; special
tools; special test, measurement, and diagnostic
equipment (TMDE), and other special support
equipment required for performance of organizational, direct support, and general support maintenance of the AN/ARC-102. It authorizes the requisitioning and issue of spares and repair parts as
indicated by the source and maintenance codes.
PA– Item procured and stocked for anticipated or
known usage.
NOTE
Cannibalization or salvage may be used as
a source of ‘supply for any items source
coded above except those coded XA and
aircraft support items as restricted by AR
700-42.
2. General
(2) Maintenance code. Maintenance codes are
assigned to indicate the levels of maintenance
authorized to USE and REPAIR support items. The
maintenance codes are entered in the third and
fourth positions of the Uniform SMR Code format as
follows:
(a} The maintenance code entered in the
third position will indicate the lowest maintenance
level authorized to remove, replace, and use the support item. The maintenance code entered in the
third position will indicate one of the following
levels of maintenance:
This Repair Parts and Special Tools List is divided
into the following sections
a. Section II. Repair Parts List. A list of spares
and repair parts authorized for use in the performance of maintenance. The list also includes parts
which must be removed for replacement of the
authorized parts. Parts lists are composed of functional groups in numeric sequence, with the parts in
each group listed in figure and item number
sequence.
b. Section III. Special Tools List. Not applicable.
c. Section IV. National Stock Number and Part
Number Index. A list, in National item identification number (NIIN) sequence, of all National stock
numbers (NSN) appearing in the listings, followed
by a list, in alphameric sequence, of all part numbers
appearing in the listings. National stock numbers
and part numbers are cross-referenced to each illustration figure and item number appearance.
3. Explanation of Columns
a. Illustration. This column is divided as follows:
(1) Figure number. Indicates the figure number of the illustration on which the item is shown.
(2) Item number. The number used to identify
item tailed out in the illustration.
b. Source, Maintenance, and Recoverability
(SMR) Codes.
(1) Source code. Source codes indicate the manner of acquiring support items for maintenance,
repair, or overhaul of end items. Source codes are
entered in the first and second positions of the Uniform SMR Code format as follows:
Code
Application/Explanation
O – Support item is removed, replaced, used at the
organizational level.
(b) The maintenance code entered in the
fourth position indicates whether the item is to be
repaired and identifies the lowest maintenance level
with the capability to perform complete repair (i. e.,
all authorized maintenance functions). This position
will contain one of the following maintenance codes:
Code
Application/Explanation
H– The lowest maintenance level capable of complete repair of the support item is the general
support level.
Z– Nonreparable. No repair is authorized.
(3) Recoverability code. Recoverability codes
are assigned to support items to indicate the disposition action on unserviceable items. The recoverability code is entered in the fifth position of the
Uniform SMR Code format as follows:
1
TM 11-5821-240-20P
Recoverability
codes
4. Special Information
Definition
Z– Nonreparable item. When unserviceable, condemn and dispose at the level indicated in position 3.
D– Reparable item. When beyond lower level
repair capability, return to depot. Condemnation and disposal not authorized below depot
level.
c. National Stock Number. Indicates the National
stock number assigned to the item and will be used
for requisitioning purposes.
d. Part Number. Indicates the primary number
used by the manufacturer (individual, company,
firm, corporation, or Government activity), which
controls the design and characteristics of the item
by means of its engineering drawings, specifications, standards, and inspection requirements to
identify an item or range of items.
NOTE
When a stock numbered item is requisitioned, the repair part received may have a
different part number than the part being
replaced.
e. Federal Supply Code for Manufacturer
(FSCM). The FSCM is a 5-digit numeric code listed
in SB 708-42 which is used to identify the manufacturer, distributor, or Government agency, etc.
f. Description. Indicates the Federal item name
and, if required, a minimum description to identify
the item.
g. Unit of Measure (U/M). Indicates the standard
of the basic quantity of the listed item as used in
performing the actual maintenance function. This
measure is expressed by a two-character alphabetical abbreviation (e.g., ea, in, pr, etc). When the unit
of measure differs from the unit of issue, the lowest
unit of issue that will satisfy the required units of
measure will be requisitioned.
h. Quantity Incorporated in Unit. Indicates the
quantity of the item used in the breakout shown on
the illustration figure, which is prepared for a functional group, subfunctional group, or an assembly.
a. The following publication pertains to the
AN/ARC-102 and its component
TM 11-5821-248-12, Radio Set AN/ARC-102
b. The illustrations in this manual are identical to
those published in TM 11-5821-248-34P. Only those
parts assigned the third position SMR maintenance
code “C” or “O’ are listed in the tabular listing;
therefore, there may be a break in the item number
sequence. Only illustrations containing organizational authorized items appear in this manual.
5. How to Locate Repair Parts
a. When National stock number or part number is
unknown.
(1) First. Using the table of contents, determine the functional group within which the item
belongs. This is necessary since illustrations are
prepared for functional groups and listings are
divided into the same groups.
(2) Second. Find the illustration covering the
functional group to which the item belongs.
(3) Third Identify the item on the illustration
and note the illustration figure and item number of
the item.
(4) Fourth. Using the Repair Parts Listing,
find the figure and item number noted on the illustration.
b. When National stock number or part number
is known.
(1) First. Using the Index of National Stock
Numbers and Part Numbers, find the pertinent
National stock number or part number. This index is
in NIIN sequence followed by a list of part numbers
in alphameric sequence, cross-referenced to the
illustration figure number and item number.
(2) Second. After finding the figure and item
number, locate the figure and item number in repair
parts list.

This fine document...
Was brought to you by me:
Liberated Manuals -- free army and government manuals
Why do I do it? I am tired of sleazy CD-ROM sellers, who take publicly
available information, slap “watermarks” and other junk on it, and sell it.
Those masters of search engine manipulation make sure that their sites that
sell free information, come up first in search engines. They did not create it...
They did not even scan it... Why should they get your money? Why are not
letting you give those free manuals to your friends?
I am setting this document FREE. This document was made by the US
Government and is NOT protected by Copyright. Feel free to share,
republish, sell and so on.
I am not asking you for donations, fees or handouts. If you can, please
provide a link to liberatedmanuals.com, so that free manuals come up first in
search engines:
