NOTE When a stock numbered item is requisitioned, the item received may have a different part number than the part being replaced. e. Federal Supply Code for Manufacturer (,. The FSCM is a 5-digit numeric code listed in SB 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. Items that are included in kits and sets are listed below the name of the kit or set with the quantity of each item in the kit or set indicated in the quantity incorporated in unit column. In the Special Tools List, the initial basis of issue (BOI) appears as the last line in the entry for each special tool, special TMI)E, and other special support equipment. 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., 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 "V" appearing in this column in lieu of a quantity indicates that no specific quantity is applicable, (e.g., shims, spacers, etc.).

12 4. Special Information a. Usable on codes are shown in the description column. Vehicle items not updated by PIP Kit 5 and other product improvement changes are identified in the RPSTL as "O" items. Those that have been updated by PIP Kit 5 and other product improvement changes are identified as "N" items. Uncoded items are common to both improved and unimproved vehicles. b. Usable on codes are shown in the description column. Vehicle items not updated by Modification Kits and and other product improvement changes are identified in the RPSTL as "O-N" items. Those that have been updated by the above modification kits and product improvement changes are identified as "N-A" items. Uncoded items are common to all vehicles. c. Detailed manufacturing instructions for items source coded to be manufactured or fabricated are found in TM maintenance manual.

The illustrations in this manual are identical to those published in the higher level of maintenance manuals, e.g. -34P and -35P. 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. Determine if repair part is a component of the Hull (Part I) or a component of Armament or Turret (Part II). Then, using the

13 table of contents, determine the functional subgroup within which the repair part belongs. This is necessary since illustrations are prepared for functional subgroups, and listings are divided into the same groups. (2) Second. Find the illustration covering the subgroup 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 Part is Known: (1) First. Determine if part is a Hull component (Part I) or an Armament and Turret component (Part II). Using the Index of National Stock Numbers and Part Numbers, find the pertinent national stock number or part number. This index is in ascending NIIN (last nine numerals) sequence, followed by a list of part numbers in ascending alpha-numeric 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. Hull components are in Part I and Armament and Turret components are in Part II. 6. Abbreviations. The abbreviations used in this publication are common in trade practice and MIL-STD-12, Military standard abbreviations for use on drawings, specifications, standards and in technical documents.
