That maintenance effort (services/actions) 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
maintenance 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

c. Column 3, Maintenance Functions.
Column 3 lists the functions to be performed on the
item listed in column 2. (For detailed explanation of these functions, see para. B-2.)
d. Column 4. Maintenance Level.
Column 4 specifies, by the listing of a “work time” figure
in the appropriate subcolumn(s), the lowest level of maintenance authorized to perform the func-

function at the indicated level of maintenance. If the number or complexity of the tasks within the
listed maintenance function vary at different maintenance levels, appropriate “work time” figures
will be shown for each level. The number of man-hours specified by the “work time” 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 operation 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. The symbol designations for the various
