GENERAL MAINTENANCE INSTRUCTIONS - CONTINUED

STANDARD TOOL REQUIREMENTS - CONTINUED

Inventory tools before and after each use.

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

When tightening fasteners, use torque value as specified in Torque Limits, WP 0245 00.

If a unique torque value is required, it will be provided in the procedural step of the task.

TAGGING INSTRUCTIONS

Use marker tags (Item 37, WP 0249 00) 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 fasten-

ers 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.

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 sche-

matic.

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, per-

form the following steps:

Clean fittings and surrounding area before disconnecting lines.

Cover, cap, plug (Item 2, WP 0249 00) or tape lines and ports after disconnecting lines. When these are not avail-

able, use plastic bags and rubber bands, clean rags (Item 29, WP 0249 00), duct tape (Item 39, WP 0249 00) or

other similar materials to prevent dirt from entering system.

Ensure that new and used parts are clean before installing.

Replace all removed tiedown straps.

Wait to remove cover, cap, plug or tape from lines and ports until just before installing lines.
