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.

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.
