7. Remove/Install - To remove and install the same item when required to perform service or other

maintenance functions. Install may be the act of emplacing, seating, or fixing into position a spare, repair

part, or module (component or assembly) in such a manner to allow the proper functioning of equipment

or system.

8. Replace - To remove an unserviceable item and install a serviceable counterpart in its place.

"Replace" is authorized by the MAC and assigned maintenance level is shown as the 3rd position code of

the SMR code.

9. Repair - The application of maintenance services, including fault location/troubleshooting, removal/-

installation, and disassembly/assembly procedures, and maintenance actions to identify troubles and

restore serviceability to an item by correcting specific damage, fault, malfunction, or failure in a part,

subassembly, module (component or assembly), end item, or system.

10. Overhaul - That maintenance effort (service/action) prescribed to restore an item to a completely

serviceable/operational condition as required by maintenance standards in appropriate technical

publications (i.e., DMWR). Overhaul is normally the highest degree of material maintenance performed

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

11. 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.

Columns In The MAC Table 1.

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

maintenance significant components, assemblies, subassemblies, and modules with the next higher

assembly. End item group number shall be "00."

2. Column 2, Component/Assembly, contains the names of components, assemblies, subassemblies,

and modules for which maintenance is authorized.

3. Column 3, Maintenance Functions, lists the functions to be performed on the item listed in Column 2.

4. Column 4, Maintenance Level, specifies each level of maintenance authorized to perform each

function listed in Column 3, by indicating work time required (expressed as man-hours in whole hours or

decimals) in the appropriate sub-column. If the number or complexity of the tasks within the listed

maintenance function varies at different maintenance levels, appropriate work-time figures will be shown

for each level. 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

operating conditions. This time includes preparation time (including any necessary disassembly/-

assembly time), troubleshooting/fault location time, and quality assurance time in addition to the time

required to perform the specific tasks identified for the maintenance functions authorized in the MAC.

5. Column 5, Tools and Test Equipment, specifies, by code, required tool and test equipment

requirements.

6. Column 6, Remarks, when applicable, contains a letter code, in alphabetical order.

Explanation of Columns In Table 2. Tool and Test Equipment Requirements

1. Column 1, Reference Code correlates with a code used in the MAC, Column 5.

2. Column 2, Maintenance Level is the lowest level of maintenance authorized to use the tool or test

equipment.
