Synthetic Heavy-Duty Grease NLGI #1 (GHB)
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. cartridges, 35-lb. pails, 120-lb. kegs and 400-lb. drums.
AMSOIL Industrial Lubricants are stocked in Superior, Wisconsin and in select regional
distribution centers throughout the United States and Canada. AMSOIL will stock additional quantities of lubricants
or special order products based on customer requests and regional demands.
