ORGANIZATIONAL PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION - CONT
(Sheet 3 of 9)
GENERAL PMCS PROCEDURES
Always perform PMCS in the same order so it gets to be a habit. Once you've had some practice, you'll spot anything wrong in a hurry. If any deficiency is discov-
ered, perform the appropriate troubleshooting task in Section IV of Chapter 2 of this manual. If any component or system is not serviceable, or if the given service
does not correct the deficiency, notify your supervisor.
Before performing preventive maintenance, read all the checks required for the applicable interval and prepare all tools needed to make all checks. Have several clean
rags (Item 16, Appendix C) handy. Perform ALL inspections at the applicable interval.
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 detergent (Item 18,
Appendix C) and water when you clean.
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 8,
Appendix C). Report it to your supervisor.
Bolts, Nuts, and Screws. Check bolts, nuts, and screws for obvious looseness, missing, bent or broken condition. Look for chipped paint, bare metal, or rust
around bolt heads. If you find one you think 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 or broken insulation, bare wires, and loose or broken connectors. Tighten loose connectors and ensure that
the wires are in good condition.
Fluid Hoses and 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 fit-
ting 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, correct it if authorized by
the Maintenance Allocation Chart (Appendix B). If not authorized, notify your supervisor.
Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your machine. The following are definitions of the types/classes of leak-
age you need to know to be able to determine the status of your machine. Learn and be familiar with them, and remember -- when in doubt, notify your super-
Leakage Definitions for Organizational PMCS
Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
Leakage of fluid great enough to form drops, but not enough to cause drops to drip from
item being checked/inspected.
Leakage of fluid great enough to form drops that fall from item being checked/inspected.
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 machine and/or components.
