TM 9-2330-371-14&P
SPECIAL INSTRUCTIONS - CONTINUED
Bolts, Nuts, and Screws. Check that they are not loose, missing, bent or broken. You can't try them
all with a tool, of course, but look for chipped paint, bare metal, or rust around bolt heads. Have
organizational maintenance tighten.
Welds. Look for loose or chipped paint, rust, or gaps where parts are welded together. If you find a
bad weld, report it to organizational maintenance.
Electric Wires and Connectors. Look for cracked or broken insulation, bare wires, and loose or
broken connectors. Have loose connectors tightened and make sure the wires are in good condition.
Hoses and Fluid Lines. Look for wear, damage, and leaks. Make sure clamps and fittings are tight.
Wet spots show leaks, of course, but a stain around a fitting or connector can mean a leak. If a leak
comes from a loose fitting or connector, tighten it. If something is broken or worn out, either correct it
or report it to organizational maintenance (refer to Maintenance Allocation Chart).
It is necessary for YOU to know how fluid leaks affect 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 status of your
equipment. Learn and be familiar with them and REMEMBER When in doubt, notify your supervisor.
LEAKAGE DEFINITIONS FOR OPERATOR/CREW PMCS
Seepage of fluid (as indicated by wetness or discolora-
Class I
tion) not great enough to form drops.
Leakage of fluid great enough to form drops, but not
Class II
enough to cause drops to drip from the item being
checked/inspected.
Leakage of fluid great enough to form drops that fall
Class III
from the item being checked/inspected.
CAUTION
Equipment operation is allowable with minor leakages (Class I or II). Of course,
consideration must be given to the fluid capacity in the item/system being
checked/inspected. When operating with Class I or II leaks, continue to check fluid
levels as required on your PMCS. Class Ill leaks should be reported to your supervisor or
organizational maintenance.
