STANDARD TOOL REQUIREMENTS CONTINUED

2. Some maintenance tasks may require special or fabricated tools. The "Initial Setup" of the procedure will
specify any special or fabricated tools needed to perform that procedure. Use these special tools only for the
maintenance procedures for which they are designed or called out. If you are unfamiliar with a required tool,
see your supervisor.
APPLYING TORQUE
00019
1. When tightening fasteners, use torque value as specified in Torque Limits (WP 0131).
2. If a unique torque value is required, it will be provided in a procedural step in the task.
TAGGING INSTRUCTIONS
00019
1. Use marker tags to identify all electrical wires, fuel, oil, coolant, and hydraulic lines, and any other parts which
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 description of the
wire and the point to which it connects, or draw a simple diagram on paper. Be sure to write down enough infor-
mation for you to 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 the 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
00019
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.
c.
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.
