CORROSION PREVENTION AND CONTROL (CPC)
Corrosion prevention and control of Army materiel is a continuing concern. It is important that any corrosion
problems with this item be reported so that the problem can be corrected and improvements can be made to
prevent the problem in future items.
Corrosion specifically occurs with metals. It is an electrochemical process that causes the degradation of
metals. It is commonly caused by exposure to moisture, acids, bases, or salts. An example is the rusting of
iron. Corrosion damage in metals can be seen, depending on the metal, as tarnishing, pitting, fogging, surface
Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation
(oxygen), solvation (solvents), or photolytic (light, typically ultraviolet) processes. The most common
exposures are excessive heat or light. Damage from these processes will appear as cracking, softening,
swelling, and/or breaking.
SF Form 368, Product Quality Deficiency Report should be submitted to the address specified in
DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual.
ARMY OIL ANALYSIS PROGRAM (AOAP)
The M917 Dump Truck Body is not enrolled in the AOAP. Hardtime intervals apply.
It is necessary to know how fluid leakage affects the status of the M917 Dump Truck Body. The following
types/classes of leakage are defined to enable the operator to be able to determine the status of the M917
Dump Truck Body equipment should a leak occur. It is essential that operators learn to identify the type/class
of leak by definition and, when in doubt, notify their supervisor.
Equipment operation is allowed with minor leakage (Class I or II).
Consideration must be given to fluid capacity in the item/system
being checked/inspected. When in doubt, notify your supervisor.
Failure to comply may result in damage to equipment.
When operating with Class I or II leaks, continue to check fluid levels as required in PMCS table. Class III
leaks will be reported immediately to your supervisor.
1. Class I Seepage of fluid (as indicated by wetness or discoloration) not great enough to form drops.
2. Class II Leakage of fluid great enough to form drops but not enough to cause drops to drip from item
3. Class III Leakage of fluid great enough to form drops that fall from item being checked/inspected.
