APPLICATION OF ADHESIVES AND SEALING COMPOUNDS
WARNING
Adhesives and sealing compounds can burn easily, can give off harmful vapors, and are harmful to skin and
clothing. To avoid injury or death, keep away from open fire and use in a well-ventilated area. If adhesive or
sealing compound contacts skin or clothing, wash immediately with soap and water.
1.
General. Adhesives are recommended in some tasks to ensure and strengthen seals. Sealing compounds are used to seal
parts against moisture. The following information describes their correct use and application.
2.
Adhesive. Adhesive provides a seal against leakage and a resistance to loosening when used in the assembly of
threaded, slip-fitted or press-fitting parts. Always use grade of adhesive specified and never use when other retaining
means are provided, such as lockwires, lock washers, lockplates, and fasteners.
3.
Sealing Compound.
a.
Anytime a seal is broken, the part must be thoroughly cleaned to remove any remaining sealing compound and
dirt.
b.
Thoroughly clean surface before applying sealing compound.
c.
When applying sealing compound, ensure that the area is completely covered. Press sealing compound into and
around parts as necessary.
d.
Sealing compound will set in 15-30 minutes depending on temperature and humidity.
STANDARD TOOL REQUIREMENTS
1.
The following are general practices regarding the use of tools:
a.
Always use the proper tool kit and tools for the procedure being performed.
b.
Ensure that tools are clean and lubricated to reduce wear and to prevent rust.
c.
Keep track of tools. Do not be careless with them.
d.
Return tools to toolbox when finished with repair or maintenance.
e.
Return toolboxes and tools to tool storage when not in use.
f.
Inventory tools before and after each use.
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.
TAGGING WIRES AND HOSES
1.
Use marker tags (Item 31, WP 0235 00) to identify all electrical wires, fuel, oil, and coolant 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 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.
