Drum For Preferred Customer and Dealer wholesale pricing please email info@fourseasonsynthetic.com 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.
