G 1. SCOPE
This appendix gives lubrication requirements for the M998 series vehicles which are the responsibility of the
G-2. GENERAL LUBRICATION REQUIREMENTS
Maintaining Lubricant Levels. Lubricant levels must be checked as specified in the PMCS (Chapter
2, Section 2) and Table G-l, Lubrication. Steps must be taken to replenish and maintain lubricant levels.
Drycleaning solvent P-D-680 is TOXIC and flammable. Wear protective goggles and gloves,
use only in well-ventilated area, avoid contact with skin, eyes, and clothes, and do not
breathe vapors. Keep away from heat and flame. Never smoke when using solvent. The
flashpoint for type I drycleaning solvent is 100°F (38°C), and for type II, is 138°F (50°C).
Failure to do so may result in injury or death to personnel.
If personnel become dizzy while using cleaning solvent, immediately get fresh air and
medical help. If solvent contacts skin or clothes, flush with cold water. If solvent contacts
eyes, immediately flush eyes with water and get medical attention.
Cleaning Fittings Before Lubrication. Clean parts with drycleaning solvent P-D-680 or equivalent.
Dry before lubricating. Dotted arrow points indicate lubrication on both sides of the equipment.
Lubrication After Fording. If fording operation occurs, lubricate all fittings below fording depth and
check submerged gear boxes for presence of water.
Lubrication After High-Pressure Washing . After a thorough washing, lubricate all grease fittings and
oil can points outside and underneath vehicle.
Localized Views. A reference to the appropriate localized view is given after most lubrication entries.
