PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)
LUBRICATION
The only component of the CK requiring scheduled lubrication is the generator set. Refer to LO
9-6115-642-12 and TM 9-6115-642-10 for lubrication procedures. The container winches, door
hinges, and corner jacks should be lubricated as necessary in accordance with the PMCS
tables.
CLEANING
Proper cleaning of the CK and its components is an integral part of maintenance. It helps
prevent possible problems in the future, so make it a habit to clean the CK and its components
whenever necessary. Refer to TM 10-7310-281-13&P for proper cleaning procedures for the
MBUs.
The generator set can be continuously operated at any time from no load up to and including
rated load. At light loads (less than 25% of set rating), an oily residue (unburned fuel oil) may
be noticed in the exhaust outlet and around connection joints in the exhaust system. This
residue is caused by the inability of the fuel injection system to consistently meter the small
amounts of fuel required to operate the generator with a light load. While this condition does not
indicate a defect in the fuel system, the oily residue could affect engine performance and create
a cosmetic problem on and around the generator set. Operation at rated load will burn off the
oily residue in a short time, depending upon the amount present. The muffler may also need to
be removed and cleaned if excessive buildup occurs. Increasing the electrical load on the set
can prevent this oily residue.
SPECIAL INSTRUCTIONS
It is necessary for you to know how fluid leakage affects the status of the CK. Following are
types/classes of leakage you need to know to be able to determine the status of the CK. Learn
these leakage definitions and remember – when in doubt, notify your supervisor.
Class I: Seepage of fluid (as indicated by wetness or discoloration) not great enough to form
drops.
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.
Equipment with minor fluid leaks (Class I or II) may be operated and is considered fully mission
capable (refer to DA PAM 738-750). Of course, you must consider the 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 by the PMCS
tables. Class III leaks should be immediately reported to your supervisor.
