CORROSION PREVENTION AND CONTROL (CPC)
CPC of Army material 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 residue, and/or
Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation (oxygen),
solvation (solvents), or photolytic (light, typically UV) 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 738-750,
Functional User Manual for the Army Maintenance Management System (TAMMS).
Oil Filter Statement. Oil filters shall be serviced/cleaned/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.
This MTRCS is not enrolled in the AOAP. HARDTIME INTERVALS APPLY.
Warranty Hardtime Statement. For equipment under manufacturer's warranty, hardtime oil service intervals shall be
followed. Intervals shall be shortened if lubricants are known to be contaminated or if operation is under adverse
conditions (such as longer-than-usual operating hours, extended idling periods, extreme dust).
FLUID LEAKAGE
It is necessary for you to know how fluid leakage affects the status of the MTRCS. Following are types/classes of
leakage you need to know to be able to determine the status of the MTRCS. Learn these leakage definitions and
remember when in doubt, notify your 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.
When operating with Class I or II leaks, continue to check fluid levels as required in the PMCS.
Class III leaks should 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 being
checked/inspected.
(3) Class III Leakage of fluid great enough to form drops that fall from item being checked/inspected.
INSPECTION
As an operator of the MTRCS, you must remain constantly alert to signs of malfunction or approaching failure. Many
troubles can be avoided by taking appropriate response to minimal maintenance needs in a timely manner.
Before, during, and after operation of the MTRCS, perform inspections to make sure all items are in good working
condition. Maintain an awareness to make sure items are correctly assembled, stowed properly, and secure. Look for
items that may be indicating excessive wear, leakage, corrosion, or improper lubrication. Correct any problems you
find, or notify Service Maintenance so that the problem can be scheduled for maintenance and correction.
