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.

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.
AMSOIL PRODUCT AVAILABILITY
