SECTION IINTRODUCTION

1. Scope

This manual lists spares and repair parts; special tools;special test, measurement, and diagnostic equipment(TMDE), and other special support equipment requiredfor performance of organizational maintenance of theSM-442A/GRC. It authorizes the requisitioning and issueof spares and repair parts as indicated by the source andmaintenance codes.

2. General

This Repair Parts and Special Tools List is divided intothe following sections:

a. Section II. Repair Parts List. A list of sparesand repair parts authorized for use in the performance ofmaintenance. The list also includes parts which must beremoved for replacement of the authorized parts. Partslists are composed of functional groups in numericsequence, with the parts in each group listed in figureand item number sequence.

b. Section III. Special Tools List. Not applicable.c. Section IV. National Stock Number arid Part

Number Index. A list, in National item identificationnumber (NIIN) sequence, of all National stock numbers(NSN) appearing in the listings, followed by a list, inalphameric sequence, of all part numbers appearing inthe listings. National stock numbers and part numbersare cross-referenced to each illustration figure and itemnumber 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 called 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 areentered in the first and second positions of the UniformSMR Code format as follows:

Code DefinitionPA - Item procured and stocked for anticipated or known

usage.

Code DefinitionXD - A support item that is not stocked. When required,

item will be procured through normal supplychannels.

NOTECannibalization or salvage may beused as a source of supply for anyitems source coded above exceptthose codes XA and aircraft supportitems as restricted by AR 700-42.

(2) Maintenance code. Maintenance codesare assigned to indicate the levels of maintenanceauthorized to USE and REPAIR support items. Themaintenance codes are entered in the third and fourthpositions of the Uniform SMR Code format as follows:

(a) The maintenance code entered in the thirdposition will indicate the lowest maintenance levelauthorized to remove, replace, and use the support item.The maintenance code entered in the third position willindicate one of the following levels of maintenance:Code Application/ExplanationO - 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 berepaired and identifies the lowest maintenance level withthe capability to perform complete repair (i.e., allauthorized maintenance functions). This position willcontain one of the following maintenance codes:Code Application/ExplanationH - The lowest maintenance level capable of complete

repair of the support item is the general supportlevel.

Z - Nonreparable. No repair is authorized.(3) Recoverability code. Recoverability codes

are assigned to support items to indicate the dispositionaction on unserviceable items. The recoverability code isentered in the fifth position of the Uniform SMR Codeformat as follows: RecoverabilityCode DefinitionZ - Nonreparable item. When unserviceable, condemn

and dispose at the level indicated in position 3.H - Reparable item. When uneconomically reparable,

condemn and dispose at the general supportlevel.

c. National Stock Number. Indicates the National

stock number assigned to the item and will be used forrequisitioning purposes.

d. Part Number. Indicates the primary numberused by the manufacturer (individual, company, firm,corporation, or Government activity), which controls thedesign and characteristics of the item by means of itsengineering drawings, specifications, standards, andinspection requirements to identify an item or range ofitems.

NOTEWhen a stock numbered item isrequisitioned, the repair part receivedmay have a different part numberthan the part being replaced.

e. Federal Supply Code for Manufacturer (FSCM).The FSCM is a 5-digit numeric code listed in SB 708-42which is used to identify the manufacturer, distributor, orGovernment agency, etc.

f Description. Indicates the Federal item nameand, if required, a minimum description to identify theitem.

g. Unit of Measure( U/M). Indicates the standard ofthe basic quantity of the listed item as used in performingthe actual maintenance function. This measure isexpressed by a two-character alphabetical abbreviation(e.g., ea, in, pr, etc). When the unit of measure differsfrom the unit of issue, the lowest unit of issue that willsatisfy the required units of measure will berequisitioned.

h. Quantity Incorporated in Unit. Indicates thequantity of the item used in the breakout shown on theillustration figure, which is prepared for a functionalgroup, subfunctional group, or an assembly.

4. Special Information

a. The following publications pertain to theSM442A/GRC and its components:TM 11-5820-467-15, Antenna Group AN/GRA-50TM 11-5820-467-24P, Antenna Group AN/GRA-50TM 11-5820-520-12, Radio Sets AN/GRC-106 andAN/GRC-106A

TM 11-5965-222-14P, Dynamic Loudspeaker LS166/UTM 11-5965-260-24P, Headset, Electrical H-140A/UTM 11-6625-847-12, Simulator, Radio FrequencySM-442A/GRC

b. The illustrations in this manual are identical tothose published in TM 11-6625-847-40P. Only thoseparts assigned the third position SMR maintenance code"C" or "O" are listed in the tabular listing; therefore, theremay be a break in the item number sequence. Onlyillustrations containing organizational authorized itemsappear in this manual.

5. How to Locate Repair Parts

a. When National stock number or part number isunknown.

(1) First. Using the table of contents,determine the functional group within which the itembelongs. This is necessary since illustrations areprepared for functional groups and listings are dividedinto the same groups.

(2) Second. Find the illustration covering thefunctional group to which the item belongs.

(3) Third. Identify the item on the illustrationand note the illustration figure and item number of theitem.

(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 isknown.

(1) First. Using the Index of National StockNumbers and Part Numbers, find the pertinent Nationalstock number or part number. This index is in NIINsequence followed by a list of part numbers inalphameric sequence, cross-referenced to the illustrationfigure number and item number.

(2) Second. After finding the figure and itemnumber, locate the figure and item number in the repairparts list.

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:
