g. If anything looks wrong and you cannot fix it, write it on your DA Form 2404. IMMEDIATELY
report it to your supervisor.
h. When you perform PMCS you will always need a rag (Item 8, App. E). One rag is required, but more
are recommended. Following are checks that are common to the entire engine assembly:
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 on all metal surfaces.
Use soap and water when you clean rubber or plastic material.
Rust and Corrosion. Check engine assembly components for rust and corrosion. If any bare
metal or corrosion exists, clean, and apply a thin coat of oil (Item 6, App. E). Report it to your
Bolts, Nuts, and Screws. Check them for obvious looseness, missing, bent, or broken
condition. You cannot check 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 that is loose, tighten it.
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
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,
3-9. CLEANING AGENTS.

tract. Skin and eye protections are required when working in contact

warning can result in injury or death to personnel.
