Overhaul. Normally, the highest degree of maintenance performed by the Army in order to minimize time and

assure that work in process is consistent with quality and economy of operation. It consists of that maintenance necessary

to restore an item to completely serviceable/operational condition as prescribed by main- tenance standards in technical

publications for each item of equipment. Overhaul normally does not return an item to like new, zero mileage, or zero hour

condition.

k. Rebuild. Consists of restoring equipment as nearly as possible to like-new condition in accordance with

original manufacturing standards. Rebuild is the highest degree of material maintenance applied to Army equipment.

Rebuild reduces to zero the hours the equipment, or component thereof, has been in use.

Column Entries

a. 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 lists the noun names of components, assemblies,

subassemblies, and modules on which maintenance is authorized.

c. Column 3. -Maintenance- Functions. Column 3 lists the functions to be performed on the item listed in

column 2.

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

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 man-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:

C - Operator/Crew

O - Organizational

F - Direct Support

L - General Support

D - Depot i
