identified with an asterisk in the allowance column.
(2) The quantitative allowances for organizational level of maintenance represents one initial prescribed load for
a 15-day period for the number of equipments supported. Units authorized additional prescribed loads will multiply the
number of prescribed loads authorized by the quantity of the repair parts reflected in the appropriate density column to
obtain the total quantity of repair parts authorized.
(3) Organizational units providing maintenance for more than 100 of these equipments shall determine the total
quantity of parts required by: First, divide the number of equipments supported by 100 by moving the decimal two spaces
left; second, multiply the result by the quantity in the 51-100 density column. Example, authorized allowance for 51-100
equipments is 40; for 150 equipments, multiply 40 by 1.50 or 60 parts required.
(4) Subsequent changes to allowances will be limited as follows: No change in the range of items is authorized.
If additional items are considered necessary, recommendations should be forwarded to U. S. Army Mobility Equipment
Command for exception or revision to the allowance list. Revision to the range of items authorized will be made by the
U.S. Army Mobility Equipment Command based on engineering experience, demand data, or TAERS information.
g. Thirty-Day DS Maintenance Allowances.
(1) The allowance column is divided into three subcolumns. Indicated in each subcolumn, opposite the first
appearance of each item, is the total quantity of items authorized for the number of equipments supported. Subsequent
appearances of the same item will have the letters "REF" in the applicable allowance column. To locate the referenced
item, locate the FSN or reference number in the index. The earliest figure and item number is the referenced item.
Items authorized for use as required but not for initial stockage are identified with an asterisk in the allowance column.
(2) The quantitative allowance for DS level of maintenance will represent initial stockage for a 30-day period for
the number of equipments supported.
(3) To determine allowances when supporting more than 100 of these equipments: First, divide the number of
equipments supported by 100 by moving the decimal two places left; second, multiply the result by the quantity in the 51
- 100 density column. Example, authorized allowance for 51-100 equipments is 40; for 150 equipments multiply 40 by
1.50 or 50 parts required.
h. One-Year Allowance Per 100 Equipments/Contingency Planning Purposes. This column indicates opposite the
first appearance of each item the total quantity required for distribution and contingency planning purposes. Subsequent
appearances of the same item will have the letters "REF" in this column. The range of items indicates total quantities of
all authorized items required to provide for adequate support of 100 equipments for one year.
i. 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. Indicates the callout number used to reference the item on the illustration.
D-4. Special Information
a. Repair parts mortality has been based on hours operation per year.
b. Parts which require manufacture or assembly of a category higher than that authorized for installation will indicate
in the source column the higher category.
c. The same illustrations are used to illustrate the repair parts and special tools listed in both organizational
maintenance section and direct support section.
D-5. How to Locate Repair Parts
a. When the Federal Stock Number or Reference Number is Unknown:
(1) First. Using the table of contents, determine the assembly group within which the repair part belongs. This is
necessary since illustrations are prepared for assembly groups, and listings are divided into the same groups.
(2) Second. Find the illustration covering the assembly group to which the repair part belongs.
