2.2.5 Leakage Definitions. You must know how fluid leakage affects the status of your equipment. The
following are definitions of the types/classes of leakage you need to know to be able to determine the sta-
tus of your equipment. Learn and be familiar with them. When in doubt, notify your supervisor.
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 the item
Leakage of fluid great enough to form drops that fall from the item being checked/inspected.
2.2.6 Operation of Generator Set 150 kW with Minor Leaks.
Equipment operation is allowable with minor leakage (Class I or ii) of
any fluid except fuel. Fluid capacity must be considered before decid-
ing to continue operation of the equipment with minor leaks. When
operating with Class I or ii leaks, fluid level must be checked more
often than required by the PMCS table. Parts without fluid will stop
working and/or cause equipment damage.
Consider the equipments capacity for the fluid that is leaking. If the capacity is small, the fluid level
may soon become too low for continued operation. If in doubt, notify your supervisor.
Check the fluid level more often than required in the PMCS table. Add fluid as needed.
2.2.7 Corrosion Prevention and Control (CPC). CPC of Army material is of continuing concern. It is
important that any corrosion problems with the equipment be reported so that the problem can be cor-
rected and improvements can be made to prevent the problem in future items. While corrosion is typically
associated with rusting of metals, it can also include deterioration of other materials, such as rubber and
plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem.
If a corrosion problem is identified, it can be reported using Standard Form 368, Product Quality Defi-
ciency Report. Use of key words such as corrosion, rust, deterioration, or cracking will ensure that
the information is identified as a CPC problem, The form should be submitted to the address specified in
DA Pam 738-750.
2.2.8 Order in Which PMCS Will be Done. Figure 2-5 shows the order in which you are to perform
your PMCS. The number callouts on figure 2-5 correspond to the numbers in the Item No. column of
table 2-4, for Before PMCS.
