Synthetic Heavy-Duty Extreme Pressure Grease
NLGI #1 and #2 (Lithium Complex
- Moly Fortified)
Extreme-pressure, moly-fortified. Provides
outstanding protection for four wheel drive steering knuckles,
spring shackles and other components operating in high-load,
low-speed conditions.
PRODUCT DESCRIPTION
AMSOIL GHD Extreme Pressure grease is qualified
against the highest grease standard, NLGI GC (wheel bearing)
and LB (chassis), and is designed for heavy duty applications.
This grease is composed of synthetic base oils and lithium-complex
thickeners that provide 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, good low temperature torque
values and good low temperature pumping capabilities. The
GHD 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.
The presence of moly provides an extra
measure of protection in shock loading situations common
in both construction and agricultural use. During heavy
shock loading, the lubricant film between metal surfaces
can be temporarily ruptured, but moly remains intact to
prevent metal to metal contact which could cause equipment
damage. Moly also assists in dirty environments or when
proper re-greasing intervals are not followed.
AMSOIL's top performing lithium complex
thickener system provides excellent water resistance as
identified by the ASTM D-1264 water washout test. Therefore,
even in wet conditions a lubricant film remains present
to protect equipment against wear while the corrosion inhibitors
prevent rust. AMSOIL GHD grease adheres to metal and is
shear stable during severe mechanical activity. These features
mean the grease does not thin during operation, but rather
it maintains its consistency and stays in place to provide
good lubrication.
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
GH EP Moly Greases are 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, thrust bearings, 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 GH greases are suitable for use up to 325º F. When
operating at elevated temperatures, frequent regreasing
may be required.
AMSOIL GH Lithium Complex Grease is 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 the GL 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.
