1. Use marker tags to identify all electrical wires, fuel, oil, coolant, and hydraulic lines, and any other parts that
may be hard to identify or replace later. Fasten tags to parts during removal by wrapping wire fasteners around
or through parts and twisting ends together. Position tags to be out of the way during cleaning, inspection, and
repair. Mark tags with a pencil, pen, or marker.
2. Whenever possible, identify electrical wires with the number of the terminal or wire to which they connect. If no
markings can be found, tag both wires, or wire and terminal, and use the same identifying mark for both. If you
cannot tag a wire because it must fit through a small hole or you cannot reach it, write down a description of the
wire and the point to which it connects, or draw a simple diagram on paper. Be sure to write down enough
information so you can properly connect the wires during assembly. If you need to identify a loose wire, look for
an identifying number near the end of the wire, stamped on a permanent metal tag. Compare that number to
wire numbers on the appropriate electrical schematic.
3. Identify fuel, oil, coolant, and hydraulic lines when you are taking off more than one line at the same time. Mark
tags with points to which lines and hoses must be connected. If it is not obvious which end of a line goes
where, tag each end of the line.
4. Identify and tag other parts by name and installed location as required.
LINES AND PORTS
To keep dirt from contaminating fluid systems when removing and installing fuel, oil, coolant, and hydraulic lines,
perform these steps:
a. Clean fittings and surrounding area before disconnecting lines.
b. Cover, cap, plug, or tape lines and ports after disconnecting lines. When these specialized covers are not
available, use plastic bags and rubber bands, clean rags, duct tape, or other similar materials to prevent
dirt from entering system.
Ensure new and used parts are clean before installing.
d. Replace all removed tiedown straps.
e. Wait to remove covers, caps, plugs, or tape from lines and ports until just before installing lines.
To prevent injury, personnel must wear protective eye covering and gloves.
When servicing equipment, performing maintenance, or disposing of materials such as
engine coolant, hydraulic fluid, lubricants, battery acids or batteries, and CARC paint,
consult your unit/local hazardous waste disposal center or safety office for local regulatory
guidance. If further information is needed, please contact the Army Environmental Hotline
Dispose of contaminated drained fluids in accordance with the Standard Operating Procedures (SOP) of your unit.
