d. Removing Seals. Be sure all traces of oil, gaskets, and sealants are removed from components. When

possible, use wood or plastic probes and scrapers to prevent damage to machined surfaces.

Do not use tape to close off fuel or oil openings. Sticky surface of tape can mix with fuel and

oil and cause engine malfunctions.

e. Parts Protection. To keep dust, dirt, moisture, and other objects out of internal parts of systems or

components, cap or tape over all open tubes, hoses, fittings, air lines and component openings as soon as part is

removed. Wrap all removed parts in clean paper or dip parts in preservation oil.

2-22. GENERAL CLEANING INSTRUCTIONS.

Drycleaning Solvent (P-D-680) is TOXIC and flammable. Wear protective goggles, face

shield, and gloves; use only in a well-ventilated area; avoid contact with skin, eyes, and

clothes, and do not breathe vapors. Keep away from heat or flame. Never smoke when

using solvent. The flashpoint for Type II Drycleaning Solvent is 140 degrees F (60 degrees

C) and Type III Drycleaning Solvent is 200 degrees F (93 degrees C). Failure to do so may

result in injury or death to personnel.

If personnel become dizzy while using cleaning solvent, immediately get fresh air and

medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts

eyes, immediately flush eyes with water and get immediate medical attention.

Never use fuel to clean parts. Fuel is highly flammable. Serious injury to personnel could

result if fuel ignites during cleaning.

a. Cleaning Solvents. Use only approved cleaning solvents to clean parts. Drycleaning solvent, P-D-680, is

commonly used. Always work in a well-ventilated area.

Compressed air used for cleaning purposes will not exceed 30 psi (207 kPa). Use only with

effective chip guarding and personal protective equipment (goggles/shield, gloves, etc). Failure

to comply may result in injury to personnel.

b. Removing Deposits. Soak parts in dry cleaning solvent, and wash away deposits by flushing or spraying.

When necessary, brush with a soft bristle brush (not wire) moistened in solvent. Use compressed air to dry parts,

except bearings, after cleaning. Bearings must drip and air dry.

c. Tools. Do not use wire brushes, abrasive wheels, or compounds to clean parts unless specifically approved in

the detailed procedures. Parts may be scratched or altered, and may weaken a highly stressed part.
