GENERAL PMCS PROCEDURES (Con't).
Keep It Clean. Dirt, grease, oil, and debris get in the way and may cover
up a serious problem. Clean as you work and as needed. Use dry cleaning solvent (tem 16,
Appendix D) on all metal surfaces. Use detergent (Item 3, Appendix D) and water when you
clean rubber, plastic, and painted surfaces.
Rust and Corrosion. Check metal parts for rust and corrosion. If any
bare metal or corrosion exists, clean and apply a light coat of lubricating oil (Item 13,
Appendix D). Report it to your supervisor.
Bolts, Nuts, and Screws. Check bolts, nuts, and screws 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 one you think is loose, tighten
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 or broken insulation,
bare wires, and loose or broken connectors. Tighten loose connectors and ensure that the
wires are in good condition.
Hoses and Fluid Lines. Look for wear, damage, and signs of leaks.
Ensure that clamps and fittings are tight. Wet spots indicate 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.
Fluid Leakage. It is necessary for you to know how fluid leakage affects
the status of your truck. The following are definitions of the types/classes of leakage you
need to know to be able to determine the status of your truck. Learn and be familiar with
them, and remember - when in doubt, notify your supervisor.
Operation is allowable with Class I and Class II leakage. WHEN IN
DOUBT, NOTIFY YOUR SUPERVISOR. When operating with Class I or
Class II leaks, check fluid levels more frequently. Class III leaks must
be reported immediately to your supervisor. Failure to do this will
result in damage to vehicle and/or components.
