5. Align.

To adjust specified variable elements of an item to bring about optimum or desired

performance.

6. Calibrate.

To determine and cause corrections to be made or to be adjusted on instruments of

test, measuring, and diagnostic equipment used in precision measurement. Consists

of comparisons of two instruments, one of which is a certified standard of known

accuracy, to detect and adjust any discrepancy in the accuracy of the instrument being

compared.

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 a manner to allow

the proper functioning of an equipment or system.

8. Replace.

To remove an unserviceable item and install a serviceable counterpart in its place. A

"Replace" is authorized by the MAC and is shown as the third position code of the

Source, Maintenance, and Recoverability (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.

NOTE

The following definitions are applicable to the "repair' maintenance function:

Services - Inspect, test, service, adjust, align, calibrate, and/or replace.

Fault location/troubleshooting - The process of investigating and detecting the

cause of equipment malfunctioning; the act of isolating a fault within a system

or Unit under Test (UUT).

Disassembly/assembly - The step by step breakdown (taking apart) of a

spare/functional group coded item to the level of its least component, that is

assigned an SMR code for the level of maintenance under consideration (i.e.

identified as maintenance significant).

Actions - Welding, grinding, riveting, straightening, facing, machining, and or

resurfacing.

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. Overhaul is normally the highest degree of

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 (e.g., hours/miles) considered in classifying Army

equipment/components.
