4-9. GENERAL PMCS PROCEDURES AND CONDITIONS (CONT).
(3) Lube oil filters. Oil filters shall bc serviced/cleancd/changed as applicable when they are known to be
contaminated, or clogged; service is recommended by AOAP laboratory analysis; or at prescribed hard time intervals.
(4) Hydraulic systems (other than brake systems) may have class III leakage and not be cause for deadlining.
Components, such as actuating cylinders, are designed to allow a certain amount of fluid to pass by the ram seal to
lubricate the seal and ram. This could be interpreted as a class III leak. The decision as to whether or not the vehicle
should be deadlined is based upon good mechanical knowledge and common sense.
(5) Corrosion prevention and control (CPC). It is important that any corrosion problem with this vehicle be
reported so that the problem can be corrected and improvements can bc made to prevent the problem in other
vehicles. Corrosion should be reported using Standard Form 368, Product Quality Deficiency Report (QDR). Use
keywords such as corrosion, rust, deterioration, or cracking to ensure that the information is identified as a CPC
problem. Send Std Form 368 to Commander, U.S. Army TACOM, Attn: AMSTA-QRD, Warren, MI 48397-5000.
Drycleaning solvent (P-D-680) is TOXIC and flammable. Wear protective goggles and gloves; use
only in a well-ventilated area; avoid contact with skin, eyes, and clothes and do not breathe vapors.
Keep away from heal of flame. Never smoke when using solvent; the flash point for type I
drycleaning solvent is 100°F (38°C) and for type II is 140°F (60°C). Failure to do so may result in
injury or death to personnel.
If personnel become dizzy while using cleaning solvent, immediately get fresh air and medical help.
If solvent contacts skin or clothes, flush with cold water. If solvent contacts eyes, immediately flush
eyes with water and get immediate medical attention.
b. Cleanliness. Dirt, grease, oil, and debris can cover and hide serious problems. Use drycleaning solvent
c. Bolts, Nuts, and Screws. Check bolts, nuts and, screws for obvious looscncss, missing, bent, or broken
condition. Look for chipped paint, bare metal, or rust around bolt heads. If any part seems loose, tighten.
d. Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If bad welds arc found,
notify direct support maintenance.
e. ELectric Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Tighten loose connectors and make sure wires arc in good shape. If bad wires or connectors are round,
replace as necessary.
f. Hydraulic Lines and Fittings. Look for wear, damage, and leaks and make sure clamps and fittings arc tight.
Wet spots show leaks, and a slain around a connector or fitting can mean a leak. If a loose fitting or connector causes
a leak, tighten it.
g. Damage is defined as: any conditions that affect safety or render the vehicle unusable for mission requirements.
h. Always perform PMCS in the same order until it becomes a habit. Once practiced, it will be easy to spot
If something does not work, refer to troubleshooting instructions in Chapter 3 and this chapter.
