B-2. MAINTENANCE FUNCTIONS. (CONT)

j. Overhaul. That maintenance effort (service/action) necessary to restore an item to a

completely serviceable/operational condition as prescribed by maintenance standards (i.e.,

DMWR) in appropriate technical publications. Overhaul is normally the highest degree of mainte-

nance performed by the Army. Overhaul does not normally return an item to like-new condition.

k. Rebuild. Consists of those services/actions necessary for the restoration of unserviceable

equipment to a like-new condition in accordance with original manufacturing standards. Rebuild is the

highest degree of material maintenance applied to Army equipment. The rebuild operation includes

the act of returning to zero those age measurements (hours, miles, etc) considered in classifying

Army equipment/components.

B-3. COLUMN ENTRIES.

a. Column 1, Group Number. Column 1 lists group numbers, the purpose of which is to identify

components, assemblies, subassemblies, and modules with the next higher assembly.

b. Column 2, Component/Assembly. Column 2 contains the noun names of components,

assemblies, subassemblies, and modules for which maintenance is authorized.

c. Column 3, Maintenance Functions. Column 3 lists the functions to be performed on the item

listed in column 2. When items are listed without maintenance functions, it is solely for purpose of

having the group numbers in the MAC and RPSTL coincide.

d. Column 4, Maintenance Category. Column 4 specifies, by the listing of a "worktime" figure in

the appropriate subcolumn(s), the lowest level of maintenance authorized to perform the function

listed in column 3. This figure represents the active time required to perform that maintenance

function at the indicated category of maintenance. If the number or complexity of the tasks within the

listed maintenance function vary at different maintenance categories, appropriate worktime figures

will be shown for each category. The number of task-hours specified by the worktime figure

represents the average time required to restore an item (assembly, subassembly, component,

module, end item, or system) to a serviceable condition under typical field operating conditions. This

time includes preparation time, troubleshooting time, and quality assurance/quality control time in

addition to the time required to perform the specific tasks identified for the maintenance functions

authorized in the maintenance allocation chart. Subcolumns of column 4 are as follows:

- Operator/Crew

- Organizational

- Direct Support

- General Support

- Depot

e. Column 5, Tools and Equipment. Column 5 specifies by code, those common tool sets (not

individual tools) and special tools, test, and support equipment required to perform the designated

function.

f. Column 6, Remarks. Column 6 contains an alphabetic code which leads to the remark in

section IV, Remarks, which is pertinent to the item opposite the particular code.
