2-2.6 Operation of Power Unit/Power Plant 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 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 re-
quired 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 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 figure shows a typical configuration having one generator set. Keep in mind that the
power plant consists of two PU-803 units and PMCS must be performed on each PU-803. The number
callouts on figure 2-2 correspond to the numbers in the Item No. column of table 2-2, for “BEFORE”
PMCS.
