PRODUCT
DESCRIPTION
AMSOIL GH Series Heavy Duty EP grease is composed
of synthetic base oils and lithium-complex thickeners that provides the
film strength, shear resistance, and mechanical stability critical to
high load protection. This combination excels in high and low operating
temperature ranges by providing excellent oxidation stability, high
temperature dropping points and good low temperature torque values and
pumping capabilities. AMSOIL Heavy Duty EP Grease is compounded with
oxidation and corrosion inhibitors, effective oil soluble EP additives
and molybdenum disulfide (moly) solid EP additives for all around
protection in severe conditions.
AMSOIL Heavy Duty EP Grease is formulated
with a top performing lithium complex thickener system that provides
excellent water resistance as identified by the ASTM D-1264 water
washout test. AMSOIL Heavy Duty EP Grease adheres to metal and is shear
stable during severe mechanical activity, maintaining consistency and
providing superior lubrication protection.

APPLICATION
RECOMMENDATION
AMSOIL GH Greases in grades
#1 and #2 are
recommended for use in manual or automatic lubricating systems. NLGI #1
(GHB) greases have better mobility and are the preferred choice for
colder applications, for automatic lubrication systems with long pumping
runs, and for gear box applications (where recommended by manufacturer).
NLGI #2 (GHD) is the preferred choice for medium to high ambient
temperatures, sleeve type bushings, high shock loading environments,
high water environments, and is the primary choice for wheel bearings.
The correct consistency grade of AMSOIL
Heavy Duty EP Grease is recommended for use in heavy and light duty
applications found in manufacturing plants, automotive applications,
agricultural equipment and construction equipment. These include, but
are not limited to, roller bearings, plain bearings, gears, bushings,
wheel bearings, chassis lubrication, universal joints, ball joints,
tie-rod ends, steering knuckles, and heavily loaded pivot pins on mining
and off road equipment such as power shovels, draglines, wheel and back
hoe loaders, excavators and bulldozers. AMSOIL Heavy Duty EP Greases are
suitable for use up to 325º F. When operating at elevated temperatures,
frequent regreasing may be required.
AMSOIL Heavy Duty EP Greases are
compatible with many other types of grease. However, it is recommended
that when changing greases, the equipment be cleaned of the old grease
when possible or flushed with a liberal amount of AMSOIL Heavy Duty EP
Grease while the mechanism is in operation. Closely monitor the system
for any inconsistencies. Any grease compatibility questions should be
referred to your AMSOIL representative or AMSOIL INC.
APPLICATION
MAINTENANCE
Maintaining a clean work environment is
important when equipment greasing is performed. Wipe grease fittings
clean prior to injecting grease to prevent contaminant ingestion.
Maintain bearing housings one-third to one-half full of grease. Do not
over-grease as excessive heat buildup can result. Supplement standard
grease maintenance by periodically cleaning and packing housings with
fresh grease on an established maintenance schedule.
