GENERAL PMCS PROCEDURES - CONTINUED
f.
Hydraulic Hoses and Lines. Look for wear, damage, and signs of leaks. Ensure that clamps and fittings are tight.
Wet spots indicate leaks, but a stain around a fitting or connector can also mean a leak. If a leak comes from a
loose fitting or connector, tighten it. If something is broken or worn out, correct it if authorized by the Maintenance
Allocation Chart (WP 0304 00). If not authorized, notify your supervisor.
g.
Fluid Leakage. It is necessary for you to know how fluid leakage affects the status of your truck. The following
are definitions of the types/classes of leakage you need to know to be able to determine the status of your truck.
Learn and be familiar with them, and remember - when in doubt, notify your supervisor.
Leakage Definitions For PMCS
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
item being checked/inspected.
Class III
Leakage of fluid great enough to form drops that fall from item being checked/inspected.
CAUTION
Operation is allowable with Class I and Class II leakage. WHEN IN DOUBT, NOTIFY YOUR SUPERVI-
SOR. When operating with Class I or Class II leaks, check fluid levels more frequently. Class III leaks must
be reported immediately to your supervisor. Failure to do this will result in damage to vehicle and/or compo-
nents.
