TAGGING PARTS - CONTINUED
If you need to identify a loose wire, look for identifying numbers stamped on a permanent metal tag, near the end of the
wire. Compare this number to the wire numbers on the electrical system schematic.
Identify hydraulic, fuel, coolant, and oil lines whenever you are taking off more than one line at the same time. Mark tags
with the points to which lines and hoses must be connected. For example, "bulkhead adapter to scarifier cylinder tube and
adapter" might be written on the tag for a hydraulic hose. If it is not obvious which end of a line goes where, tag each end
of the line.
Identify other parts as necessary by name and installed location.
Use a low-wattage soldering gun when soldering electrical wires, connectors, terminal lugs, and
receptacles. A high-wattage soldering gun may damage parts by overheating them.
Solder connections must be bright and clean before soldering. Take off dirt and grease with cleaning compound and small
stiff fiber brush. Solder (item 18, appendix C) must be nonacid type. Use rosin flux (item 9, appendix C). All wires, parts,
and soldering gun must be pretinned for good connection and maximum transfer of heat.
To prevent overheating damage to electrical parts when soldering and unsoldering connections, hold bare wire, lead, or
terminal lug close to soldering point with long roundnose pliers. Pliers act as a heat sink, absorbing excess heat. Clean all
solder joints with an acid swabbing brush and cleaning compound, after soldering, to get a bright clean surface.
HEAT SHRINKABLE TUBING
Heat shrinkable tubing (item 27, appendix C) is used to insulate soldered and crimped electrical connections as follows:
Cut desired length of new tubing twice the diameter of the connection to be covered.
Slide tubing onto wire and out of the way before making connection.
After making electrical connections, slide tubing into place over it.
Do not touch heat shrinkable tubing for at least 30 seconds after heating. Hot tubing can burn
