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 Grease in grade #2 is
recommended for use in manual or automatic lubricating systems. 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.
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
AMSOIL GHD Grease is available in 14-oz. cartridges and
16-oz. tubs.
