GENERAL MAINTENANCE PROCEDURE - Continued
Welds: Look for loose or chipped paint, rust, or gaps where parts are welded together. If a damaged weld
is discovered, have it repaired.
Electric Wires and Connectors: Look for cracked or broken insulation, bare wires, and loose or broken
connectors. Tighten loose connectors, and ensure wires are in good working condition.
Hydraulic Lines and Fittings: Look for signs of wear, damage, and leaks. Ensure clamps and fittings are
tight. Wet spots as well as stains around fittings and connectors can indicate leaks.
FLUID LEAKAGE
It is necessary to know how fluid leakage affects the status of fuel, oil, coolant, and the hydraulic systems.
NOTE
Equipment operation is allowable with minor leakage (Class I or Class II). Fluid capacity
must be considered when inspecting an item or system. If leakage class is questionable,
notify the supervisor. When operating with Class I or Class II leaks, continue to check fluid
levels as required in the PMCS. Class III leaks should be repaired per applicable
procedure.
Class I: Seepage of fluid (as indicated by wetness or discoloration) not sufficient enough to form drops.
Class II: Leakage of fluid sufficient enough to form drops, but not sufficient enough to cause drops to drip
from item being inspected.
Class III: Leakage of fluid sufficient enough to form drops that fall from the item being inspected.
ARMY OIL ANALYSIS PROGRAM (AOAP)
Engine, transmission, and hydraulic oil and filter replacement are governed by AOAP program. If there is no
AOAP lab available, oil and filter changes will be conducted according to the PMCS table.
LUBRICATION INSTRUCTIONS
During adverse weather or unusually dusty conditions, lubrication servicing may be required on a daily
basis.
After fording operations, lubricate all lubrication points below fording line.
All lubrication instructions are mandatory.
