INTRODUCTION

TM 11-6625-1576-24P

1. Scope.

This manual lists repair parts required for performance of organizational and general support maintenance of the AN/URM-180 and the AN/URM-184A.

2. General.

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

a. Section II. Repair Parts List. A list of 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 ascending numerical 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 ascending numerical sequence, of all National stock numbers appearing in the listings, followed by a list, in alphanumeric 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.

The following provides an explanation of columns found in the tabular listings:

a. Illustration.

This column is divided as

follows:

(1) Figure number. Indicates the figure number of the illustration in which the item is shown.

(2) Item number. The number used to identify

each item called out in the illustration.

b. Source,

Maintenance,

and Recoverability

Codes (SMR).

(1) Source code. Source codes are assigned to

support items to 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

Definition

PA – Item procured and stocked for anticipated or

known usage.

XD – A support item that is not stocked. When

Code

Definition

required, item will be procured through normal supply channels.

AH – Item to be assembled at general support

maintenance level.

NOTE

Cannibalization or salvage may be used as a source of supply for any items sourcecoded above, except those coded XA, XD, and aircraft support items as restricted by AR 700-42.

(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:

Code

Application/Explanation

O – Support item is removed, replaced, used at the

organizational level.

H – Support item is removed, replaced, used at the

general support 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:

Recoverability

Code

general support level.

c. National Stock Number.

National stock number assigned 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 requirements, to identify an item or range of items.

When a 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. When the part to be used differs between serial numbers of the same model, the effective serial numbers are shown as the last line of the description.

g. Unit of Measure (U/M). Indicates the standard of the basic quantity of the listed item as used in performing the actual maintenance func-

tion. 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 assembly.

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 repair part 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 repair part belongs.

(3) Third. Identify

the repair part on the illustration and note the illustration figure and item number of the repair part.

(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 ascending NSN sequence, followed by a list of part numbers in ascending alphanumeric 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 the repair parts list.

6. Abbreviations.
