TM 9-6115-660-13&P
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 fall from the item being checked/inspected.
2-2.6 Operation of Power Plant/Power Unit with Minor Leaks.
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.
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 materiel is of continuing concern. It is important that any
corrosion problems with the power plant or power unit be reposed 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
"racking" 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. Figures 2-2, 2-3, and 2-3.1 show the order in which you are t perform your
before operation PMCS. Figure 2-2 is for the AN/MJQ-37 and AN/MJQ-38, figure 2-3 is for PU-798 and PU-799, and
figure 2-3.1 is for PU-798A and PU-799A. The number callouts on figures 2-2, 2-3, and 2-3.1 correspond t the numbers in
the Item No. column of table 2-2. Callouts on figure 2-2 for one Power Plant generator set apply to both of the Power Plant
generator sets.
