Extreme-pressure, moly-fortified. Provides outstanding protection for four wheel drive steering knuckles, spring shackles, heavy equipment pivot joints and other components operating in high-load, low-speed conditions. NLGI #1 is preferred for cold temperatures and auto pumping systems. Offers excellent water washout resistance.
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 Heavy Duty EP Grease in grade #1 is recommended
for use in manual or automatic lubricating systems. NLGI #1 (GHB) grease has
better mobility and is the preferred choice for colder applications, automatic
lubrication systems with long pumping runs and other applications (where recommended
by manufacturer).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
#1 and #2 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.
AMSOIL PRODUCT AVAILABILITY
AMSOIL GH Series Greases are available in 14-oz.
