TM 5-4320-200-1 3&P
If the pump does not perform as required, refer to Chapter 3, Section II, Troubleshooting.
If anything looks wrong and you can’t fix it, write it on your DA Form 2404. IMMEDIATELY, report
it to your supervisor.
When you do your PMCS, you will always need a rag or two. Following are checks that are common
to the entire pump:
—
Keep It Clean. Dirt, grease, oil, and debris only get in the way and may cover up a serious
problem. Clean as you work and as needed. Use dry cleaning solvent (SD-2) on all metal surfaces. Use soap
and water when you clean rubber or plastic material. Upholstery can be cleaned with soap and water and
a clean, damp cloth.
Rust and Corrosion. Check pump body and frame for rust and corrosion. If any bare metal or
corrosion exists, clean, and apply a thin coat of oil. Report it to your supervisor.
Bolts, Nuts, and Screws. Check them all for obvious looseness, missing, bent, or broken
condition. You can’t try them all with a tool, but look for chipped paint, bare metal, or rust around bolt heads.
If you find a bolt, nut, or screw you think is loose, tighten it or report it to your supervisor.
Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you
find a bad weld, report it to your supervisor.
Electric Wires and Connectors, Look for cracked, frayed, or broken insulation, bare wires, and
loose or broken connectors. Tighten loose connectors. Report any damaged wires to your supervisor.
Hoses and Fluid Lines. Look for wear, damage, and leaks, and make sure clamps and fittings
are tight. Wet spots show leaks, but a stain around a fitting or connector can also mean a leak. If a leak comes
from a loose fitting or connector, tighten it. If something is broken or worn out, report it to your supervisor.
When you check for “operating condition,” you look at the component to see if it’s serviceable.
2-3. CLEANING AGENTS.
2-4
DO NOT use diesel fuel, gasoline, or benzene (benzol) for cleaning.
DO NOT SMOKE when using cleaning solvent. NEVER USE IT NEAR AN OPEN
FLAME. Be sure there is a fire extinguisher nearby and use cleaning solvent only in
well-ventilated places. Flash point of solvent is 138°F (60°C).
USE CAUTION when using cleaning solvents. Cleaning solvents evaporate quickly and
can irritate exposed skin if solvents contact skin. In cold weather, contact of exposed skin
with cleaning solvents can cause frostbite.
