ITEM Column. The item number is the number assigned to the item as it appears in the figure referenced in
the adjacent figure number column.
The Usable on Code title appears in the lower right corner of column (5), Description. Usable on codes are
shown in the right-hand margin of the description column. Identification of the usable on codes used in the
Fabrication Instructions. Bulk materials required to manufacture items are listed in the bulk material
functional group of this RPSTL. Part numbers for bulk material are also referenced in the Description
Column of the line item entry for the item to be manufactured/fabricated. Detailed fabrication instructions
for items source coded to be manufactured or fabricated are found in this TM.
Index Numbers. Items that have the word BULK in the figure column will have an index number shown in
the item number column. This index number is a cross-reference between the NSN / P/N index work
packages and the bulk material list in the repair parts list work package.
Illustration List. The illustrations in this RPSTL contain unit authorized items. Illustrations published in this
TM that contain unit authorized items also appear in this RPSTL. The tabular list in the repair parts list work
package contains only those parts coded O in the third position of the SMR code, therefore, there may be
a break in the item number sequence.
HOW TO LOCATE REPAIR PARTS
1. When National Stock Number or Part Number is Not Known.
First. Using the table of contents, determine the assembly group or sub-functional group to which the item
belongs. This is necessary since the figures are prepared for functional groups and sub-assembly groups,
and lists are divided into the same groups.
Second. Find the item covering the figure covering the functional group or sub-functional group to which
the item belongs.
Third. Identify the item on the figure and note the number(s).
Fourth. Look in the repair parts list work packages for the figure and item numbers. The NSNs and part
numbers are on the same line as the associated item numbers.
2. When NSN is Known.
First. If you have the NSN, look in the STOCK NUMBER column of the NSN index work package. The
NSN is arranged in NIIN sequence. Note the figure and item number next to the NSN.
Second. Turn to the figure and locate the item number. Verify that it is the one you are looking for.
