TAGGING WIRES AND HOSES - Continued
Whenever possible, identify electrical wires with the number of the terminal or wire to which it connects. 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 the 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 will be able to properly connect the wires during assembly. If you need to identify a loose
wire, look for identifying number near end of the wire, stamped on a permanent metal tag. Compare the number
to wire numbers on the appropriate electrical schematic.
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.
Identify and tag other parts as required by name and installed location.
LINES AND PORTS
To keep dirt from contaminating fluid systems when removing and installing fuel, oil, coolant, and hydraulic
lines, perform the following steps:
Clean fittings and surrounding area before disconnecting lines.
Cover, cap, plug, or tape lines and ports after disconnecting lines. When these are not available, use
plastic bags and rubber bands, clean rags, duct tape, or other similar materials to prevent dirt from
Ensure that new and used parts are clean before installing.
Replace all clamps and tiedown straps.
Wait to remove cover, cap, plug, or tape from lines and ports until just before installing lines.
When servicing this vehicle, performing maintenance, or disposing of materials such as
engine coolant, hydraulic fluid, lubricants, battery acids, or batteries, 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 at 1-800-872-3845.
Dispose of contaminated drained fluids IAW Standard Operating Procedures (SOP) of your unit.
