Leakage
Class
Leakage Definition
Class II
Leakage of fluid great enough to form drops, but not enough to cause drops to drip from
the item being checked/inspected.
Class III
Leakage of fluid great enough to form drops that drip from the item being
checked/inspected.
2.2.6. Operation of Generator Set with Minor Leaks.
a. Consider the equipment's 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.
b. 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
corrected 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 Deficiency 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 2-2 shows the order in which you are to perform
your PMCS. The number callouts on Figure 2-2 correspond to the numbers in the Item No. column of
Table 2-2, for "Before" PMCS.
2.2.9. Warnings, Cautions, and Notes. Always observe WARNINGS, CAUTIONS, and NOTES
appearing in your PMCS table. Warnings and cautions appear before applicable procedures. You must
observe WARNINGS to prevent serious injury or death to yourself and others. You must observe
CAUTIONS to prevent your equipment from being damaged. You must observe NOTES to ensure
procedures are performed properly.
CAUTION
Equipment operation is allowable with minor leakage
(Class I or II) of any fluid except fuel. Fluid capacity
must be considered before deciding 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.
