FLUID LEAKAGE
00012
N OT E
Notify Field Level Maintenance of any leaks the operator cannot fix.
It is necessary for you to know how fluid leakage affects the status of the 120M Motor Grader. Following are types/
classes of leakage you need to know to be able to determine the status of the 120M Motor Grader. Learn these
leakage definitions and remember - when in doubt, notify your supervisor. Equipment operation is allowed with
minor leakage (Class I or II). Consideration must be given to 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 in the PMCS.
Class III leaks should be reported immediately to 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 the item being checked/inspected.
Class III
Leakage of fluid great enough to form drops that fall from the item being
checked/inspected.
GENERAL LUBRICATION PROCEDURES
00012
N OT E
Refer to Lubrication Order (LO 5-3805-293-13).
1. Recommended intervals are based on normal conditions of operation, temperature, and humidity. When
operating under extreme conditions, lubricants should always be changed more frequently. When in doubt,
notify your supervisor.
2. Keep all lubricants in a closed container and store in a clean, dry place away from extreme heat or cold. Keep
container covers clean and do not allow dust, dirt, or other foreign material to mix with lubricants. Keep all
lubrication equipment clean and ready for use.
3. Maintain a good record of all lubrication performed and report any problems noted during lubrication. Refer to
DA PAM 750-8 for maintenance forms and procedures to record and report any findings.
4. Keep all external parts of equipment not requiring lubrication free of lubricants. Before lubrication, wipe
lubrication fittings with a clean Rag, Wiping (WP 0032, Item 17). After lubrication, wipe off excess oil or grease
to prevent accumulation of foreign matter.
5. Refer to FM 9-207 for lubrication instructions in cold weather.
6. Refer to AR 70-12 for use of standardized lubricants.
