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.
PERFORMANCE FEATURES
- Moly Fortified for added EP
protection
- Adhesive and Shear Stable - prevents
squeeze out
- High dropping point (exceeds
500ºF)
- Excellent water-washout
resistance
- Oxidation and corrosion
inhibited
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.
