TM 5-5420-278-24&P0018 000018 00-2PREVENTIVE MAINTENANCE CHECKS AND SERVICES (Contd)CORROSION PREVENTION AND CONTROL (CPC)a. Corrosion prevention and control (CPC) of Army materiel is a continuing concern. It is importantthat corrosion problems are reported so they can be corrected and improvements can be made to preventfuture problems.b. While corrosion is typically associated with rusting of metals, it can also include deterioration ofother materials, such as rubber and plastic. Unusual cracking, softening, swelling, or breaking of thesematerials may be a corrosion problem.c. If a corrosion problem is identified, it can be reported using Standard Form 368, Product QualityDeficiency Report. Use of key words such as corrosion, rust, deterioration, or cracking will ensure that theinformation is identified as a CPC problem.d. The form should be submitted to the address specified in DA Pam 738-750.SPECIAL INSTRUCTIONSPreventive maintenance is not limited to performing the checks and services listed in the PMCS table.a. Keep it clean. Dirt, grease, oil, and debris get in the way and may cover up a serious problem.Clean work area as needed. Use Skysol-100 on all metal surfaces. Use soap and water to clean rubber orplastic material.b. Bolts, nuts, and screws. Check them all for obvious loose, missing, bent, or broken condition.Look for chipped paint, bare metal, or rust around bolt heads; check and tighten where necessary.c. Fluid lines. Look for wear, damage, and leaks. Make sure clamps and fittings are tight. Wet spotsand stains around a fitting or connector can mean a leak. If a leak comes from a loose connector, tightenit. If something is broken or worn out, refer to the appropriate maintenance work package (WP) task andrepair or replace it.d. Data plates. Check all data plates. If any plate is worn, broken, painted over, missing hardware,or unreadable, it must be replaced. (Refer to WP 0085 00.)LEAKSa. It is necessary to know how fluid leaks affect equipment operation and readiness. The followingdefinitions for types/classes of leakage shall be observed.Class ISeepage of fluid (as indicated by wetness or discoloration) not great enough to formdrops.Class IILeakage of fluid great enough to form drops but not enough to cause drops to drip fromitem being checked/inspected.Class IIILeakage of fluid great enough to form drops that fall from the item beingchecked/inspected.b. Identify and report any sign of leakage, and perform all maintenance and repair; refer to Ramp BayPump System Maintenance (WP 0031 00).c. Under emergency conditions where use of the IRB pump system is necessary to complete themission, consideration must be given to the fluid capacity and the leak classification. Class III leaks mustbe reported to the maintenance supervisor immediately.PAINTINGPaint touch-up of the IRB should be performed as needed during PMCS. Refer to painting instructions(WP 0076 00).
