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.
